IOTA Smartphone — The First Blockchain Smartphone

Sirin Labs

Sirin Labs, the company behind a $16,000 luxury Solarin phone, has just announced the new smartphone project based on blockchain technology.

The first blockchain technology smartphone — IOTA smartphone — will be significantly cheaper to its predecessor, priced at $1,000. It is designed for blockchain/cryptocurrency followers, and the feeless IOTA technology will support it.

‘Finney’ is aimed at a niche, crypto orientated audience of early adopters who are expected to be lured by its bulletproof security features.

The smartphone project from Sirin Labs is just a beginning of creating an entire family of ‘Finney’ devices that will be a secure, open-source, electronics for the blockchain era customers.

The phone will be named after the scientist Hal Finney who was the first recipient of a Bitcoin transaction. The new smartphone will be based on an open-source, secure network that will run on a blockless Tangle technology, powered by IOTA.

Sirin Labs

Unlike most smartphones, ‘Finney’ will come with a 256GB internal memory, 16-megapixel camera and impressive security features. Thanks to blockchain technology, the security measures will be more robust than traditional smartphone protection, it also guarantees a much higher memory capacity.

The phone will be equipped with a physical security switch, a behavioural-based intrusion detection system and blockchain-based inference system. So, in theory, the phone will be almost impossible to hack.

The smartphone will be the first product to come from underneath the ‘Finney’ family. There are already plans on building a PC that will be capable of wireless data sharing, battery power and processing power.

Sirin Labs is launching a crowdsale in October 2017 with a hope to raise funds for the network development. It will operate without mining centres and blocks that can clutter and slow down the data transaction process.

By using the default SRN token as a native currency, the network will run on a Sirin operating system, designed on purpose to support blockchain applications, cryptocurrency wallets, with an extremely high level of security. Only SRN token holders will be able to purchase the device.

IOTA is the newest blockchain technology invention, focused on free machine-to-machine payments that fuel IoT. If you don’t own IOTA yet, you can buy it with USD or BTC on Bitfinex.

Once built, the devices will revolutionise the everyday use of blockchain technology and cryptocurrency. Helping the same with the mass adoption of blockchain and cryptocurrency.

The crowdsale details of IOTA smartphone should be released later on this month.

Quantum IOTA

IOTA appears as having a most versatile solution to the challenge of asynchronous trust, avoiding the bitcoin blockchain bottleneck. And as such it is the most attractive platform for the vision of quantum trust building. Its robust validation history will be a collapsed option selected from a superposition of the same. And unlike quantum physics where the superposition generating laws are fixed, in designing a network, the applicable platform law (rule) itself may be a collapsed option from a super position of applicable laws. Reverse engineering should be exponentially difficult. A good quantum simulation can be achieved via the BitFlip protocol.

Уязвимость в коде IOTA или почему курс обвалился на 25%

Многие, наверно, заметили обвал курса IOTA сегодня (08 сентября 2017).

Произошло это после публикации статьи Neha Narula, директора Digital Currency Initiative at the MIT Media Lab (DCI). В статье она рассказала о том, что ещё 14-го июля её коллеги нашли в коде IOTA уязвимость. Об этом было извещено руководство IOTA. Уязвимость была устранена посредством выпуска патча. И уже 7-го августа DCI официально подтвердили отсутствие уязвимости. Только после этого новость была опубликована публично. Сама статья Neha, как на меня, немного “хейтерская”. Думаю, можно было бы и по сдержанней быть.

Кому хочется вникнуть в суть произошедшего могу порекомендовать опубликованную переписку одного из основателей IOTA Foundation Сергей ИВАНЧЕГЛО и команды DCI. Там всё очень подробно и в красках, правда на английском. Ещё интересная статья .

Мой вывод — IOTA “объявила распродажу” сегодня -25% ))) Почему так, да потому, что уже месяц как нет причины сегодняшней новости, а курс упал только только сегодня. Уверен подымется так же стремительно…

Curl disclosure, beyond the headline

As part of an on-going conversation between the IOTA Team and security researchers from Boston University and MIT DCI, the teams published their report on a vulnerability in Curl today. On August 8th, the IOTA Team implemented a safety precaution by switching Curl with Keccak-384 (wrapped as “Kerl”, as a tongue-in-cheek homage to what it was replacing), but no user funds were ever at risk prior to the upgrade.

We greatly appreciate the disclosure made by the researchers as this will further help to bring IOTA into production-readiness and mainstream adoption. We do, however, have some comments to make on the otherwise strongly worded publication by Narula et al.

As many may already know, we have already discussed this at length for months, and the network uses KECCAK-384 for signing purposes.

Regarding the practicality of attacks

The attacks presented in Narula et al.’s paper, while being valid academic criticisms of the latest public version of the Curl hash function, do not represent valid attacks on the IOTA cryptocurrency. Here’s why:

Forging signatures on IOTA payments

The “waste money” and “steal money” attacks primarily rely on Eve being able to goad Alice into signing bundles crafted by Eve and then being faster in getting her bundle confirmed than Alice’s:

Firstly, none of the existing IOTA wallets offer this functionality of signing foreign bundles — Alice would therefore have to be a proficient programmer to manually sign a bundle using existing libraries and naive enough to sign a bundle she did not create.

Secondly, for Eve to be able to generate such a bundle in the first place, Eve would have to know which addresses belong to Alice. Eve can not calculate addresses belonging to Alice from knowing just one of Alice’s addresses, so this attack would require prior seed compromise by Eve (making the entire attack moot) or Alice leaking her address to Eve in the first place.

Thirdly, only one of each of Eve’s bundles can exist on an IOTA node at any given time. Without Eve having better network propagation than Alice or executing a successful eclipse attack against Alice, Eve would not be successful in being able to see her malicious bundle confirmed before Alice’s bundle is confirmed. However, the mesh network characteristics of the IOTA network make such an eclipse attack very hard to implement.

These requirements are exceptionally unlikely to occur in practice, making the presented attack impractical — even less so when combined with the earlier points.

However, the work of Narula et. al. is a valuable addition to the growing work of a number of academics that are reviewing the Tangle network.

Still, systems with few moving parts provide excellent subjects of study for an analysis of this depth. The IOTA Cryptocurrency is not one of those systems and thus context is very important when claiming a practical attack on a system.

Onward and Upwards

The necessity for greater collaboration between academia and the Crypto-Currency community is of paramount importance. Only by working together, leaving any conflict of interest aside, can we build better systems to serve mankind (or the Machine Economy). For an outsider, it can sometimes be difficult to access the academic community and get the necessary support on sensitive subjects. The IOTA Team has previously reached out to several renown cryptographers in this space, many of whom (including researchers from this publication) have been unable to work with us, often due to conflicts of interest.

We have since formed stronger partnerships with several large academic institutions around the world, and will continue to do so. As for Curl, the IOTA Foundation has already subcontracted a team of 5 world-class cryptographers, as well as 3 independent ones to come up with a final design of Curl and then start the long peer-reviewed process, as was always the plan. No change.

The IOTA Team will continue to work diligently (and tirelessly) to make IOTA the first production-ready distributed ledger protocol. When it comes to security, you can never be safe enough. We hope that researchers, whether independent or from academic institutions, will continue to join us on this path to build a protocol that is scalable, sound and secure.

Notes

Before we conclude this post, we would like to correct the following misrepresentations in the researchers’ post:

  • The transaction size is only 1.6KB at rest (not 10kb as stated in the document)
  • The replacement Kerl hash function is unmodified KECCAK-384 that only converts its input and output from/to 243 trits to 48 bytes using basic two’s complement. KECCAK-384 is well vetted and researched.

The IOTA Team


Curl disclosure, beyond the headline was originally published in IOTA on Medium, where people are continuing the conversation by highlighting and responding to this story.

Breaking down the IOTA IRI Source

I decided I wanted to know more about how IOTA works, so I figured the best was is to “Use the Source Luke” and just look at the code. Like most software projects, it is desperately lacking in comments, so I’m going to have to make some guesses at how it works.

The IRI (IOTA Reference Implementation) is written in Java and is hosted on Github as an open source project under the GPLv3 License. The README has a pretty good getting started guide, so that won’t be covered here, I’ll just jump right in.

The Entrypoint

The main function is the entry point and can be found in src/main/java/com/iota/iri/IRI.java

The first thing that happens is parsing the command line arguments as defined in the README.

Next it configures the main business logic classes: Iota, IXI and API and initialises them. It also sets up a shutdown hook that is run when the process exists which seems to just do some cleanup on these classes.

iota = new Iota(configuration);        
ixi = new IXI(iota);
api = new API(iota, ixi);
...
iota.init();
api.init(); ixi.init(configuration.string(Configuration.DefaultConfSettings.IXI_DIR));

Interestingly the main function ends here without handing off to some sort of loop, so I assume that a separate thread or another process is running as a side effect of the init calls, which keeps the process alive. (Looks like this is done by the API Server, see below).

Breaking down the classes

As you can see from the code snippet above, the organisation of the code seems to be: the API depends on IXI and Iota classes, and IXI also depends on Iota, so I’ll break these down in the following order: Iota, IXI, API.

Iota

This class creates and initialises all of the core database and message passing functionality of the IOTA node. It uses ZMQ for message passing (seemingly this is used for analytics, but that is not obvious) and RocksDB to persistently store the transactions in the tangle. Mostly this is just further delegating initialisation to subsystems. It seems that this class just holds a bunch of other objects as public parameters and acts as a “God object” — a singleton that collects all the various services and managers that the rest of the program requires, such as configuration settings etc.

IXI

I think IXI stands for IOTA Execution Interface or something like that. It seems to be setting up a Javascript engine for scripting purposes. It looks like it creates a thread that watches the file system and reloads the scripts into the Javascript context when they change.

The attach method is doing the work of loading the script.

private void attach(Path pathToMain, String moduleName) {
Reader ixiModuleReader;
try {
ixiModuleReader = new FileReader(pathToMain.toFile());
} catch (FileNotFoundException e) {
log.error("Could not load " + pathToMain);
return;
}
log.info("Starting script: " + pathToMain);
Map<String, CallableRequest<AbstractResponse>> ixiMap = new HashMap<>();
Map<String, Runnable> startStop = new HashMap<>();
Bindings bindings = scriptEngine.createBindings();
bindings.put("API", ixiMap);
bindings.put("IXICycle", startStop);
bindings.put("IOTA", iota);
ixiAPI.put(moduleName, ixiMap);
ixiLifetime.put(moduleName, startStop);
try {
scriptEngine.eval(ixiModuleReader, bindings);
} catch (ScriptException e) {
log.error("Script error");
}
try {
ixiModuleReader.close();
} catch (IOException e) {
log.error("Could not close " + pathToMain);
}
}

The Iota object is added to the module’s binding (global scope?) when the script is loaded, along with a map called “API” to register commands (functions) against a command name (presumably from the API class), and a map called “IXICycle” for lifecycle functions which are called when the module has lifecycle changes (only “shutdown” is called at the moment).

private void detach(String moduleName) {
Map<String, Runnable> ixiMap = ixiLifetime.get(moduleName);
if(ixiMap != null) {
Runnable stop = ixiMap.get("shutdown");
if (stop != null) stop.run();
}
ixiLifetime.remove(moduleName);
}

The processCommand method looks up the command in the ixAPI map and calls it if it matches by module name, then subcommand. For example, if you have a module called “foo” loaded with a command “bar” registered in its API function, the command foo bar would execute that. The command is also given a Map<String,Object>which it uses as the argument to the function call.

public AbstractResponse processCommand(final String command, Map<String, Object> request) {
Map<String, CallableRequest<AbstractResponse>> ixiMap;
AbstractResponse res;
String substring;
for (String key: ixiAPI.keySet()) {
substring = command.substring(0, key.length());
if(substring.equals(key)) {
String subCmd = command.substring(key.length()+1);
ixiMap = ixiAPI.get(key);
res = ixiMap.get(subCmd).call(request);
if(res != null) return res;
}
}
return null;
}

Interestingly, the code doesn’t check that the subcommand exists in the API mapping, so passing a command that doesn’t exist could cause an error, maybe that is expected though.

API

This manages the JSON API for the node, utilising the Undertow HTTP server. The full API documentation can be found here.

Messages are sent as a JSON object to the / path of the server with a command key to specify the command to be executed and the remaining keys acting as parameters for the request. These are parsed in the process method to ensure that the required parameters are provided, and that they are the correct format, then the appropriate controller method is called. Mostly this consists of just calling methods on the Iota class’ various public member variables (most notably the Node one).

Any commands that are not recognised are passed to the IXI to be processed.

default: {
AbstractResponse response = ixi.processCommand(command, request);
return response == null ? ErrorResponse.create("Command [" + command + "] is unknown") : response;
}

Other Notable Classes

The above seem to be the main “entrypoints” into the code, with the API class being the core of the business logic to get the Node to do things, but I noted some other important classes.

Node

Handles neighbour connections and messaging parsing/broadcasting. When a new transaction comes in via the API, it is broadcast to the neighbours using the Node class. Additionally, the neighbours will send transactions they receive, which this node then stores and re-broadcasts to its neighbours.

Tangle

Maps interaction such as adding transactions etc to a set of PersistenceProviders. There is a RocksDB, FileBased and ZeroMQ persistence provider. The RocksDB one seems to be the only one that actually provides persistence however, the other two just write out update logs to a file and a ZeroMQ topic.

TipsManager

Creates a thread that scans the Tangle every x seconds to find the current set of Tips (transactions that have no approvers). Marks tips that now have approvers as solid once they are found. Provides methods for selecting random tips (presumably for finding transactions to approve when creating a new transaction).

General Comments

The code is what I would consider “okay”. It utilises a God object instead of Dependency Injection and uses a lot of thread synchronisation instead of utilising serial worker queues and asynchronous code, which would improve the thread safety of the code. It doesn’t seem to use a lot of interfaces or even getter/setter methods, and some methods in the API class are doing too much and could be refactored into method calls on controller classes. There are also some pretty big issues around the imperative nature of the API. For example, the “ attachToTangle” command does the computation required to hash a transaction, but stores the hasher computation(PearlDriver) in a member variable — the “ interruptAttachingToTangle” command then cancels this object’s computation, but if you have called “attachToTangle” again in the meantime then there’s no way to stop the previous hashing computation. Really each hashing computation job should be given an ID that can be referenced in the “interruptAttachingToTangle” command.

Ideally the server would use a RESTful JSON interface instead of this adhoc RPC one.

Next Time

I plan on looking deeper into the node-to-node communication protocol, database layer and the intended purpose of the ZeroMQ server.

Proof-of-Humanity Networks (Honest Bitcoin)

Bitcoin, Ethereum, IOTA and their likes, are all vulnerable to “fake nodes attack” — harm done by nodes that pose as valid traders, and bona fide transactional entities, while in fact they are “empty identities” — nodes that are established by an abuser in order to exploit the singular source of power of the network: nodes count, nodes majority. Bitcoin (and the others) claim to fame is in the notion that the protocol prevents any minority of nodes to take control of the network. Indeed, whether you go with proof of work, or with proof of stake, or with proof of past, or alike — the power lies within a community of nodes. And so, any network in which nodes can be “faked”, where a single manipulator can readily concoct hundred, thousands, and more nodes mimicking a crowd of bonafide traders, is a network that will fall prey to such node inflation abuse.

Say then that to defend any network protocol based on decentralized power, it is necessary to eliminate fake nodes. When it comes to trading money, we need to develop a “proof of humanity”, proof that any participating node is associated with a verified human being. Some humans could have more than one node, but all their nodes will be associated with their singular human being, allowing the protocol to account for that.

What about corporations? They will have to be listed per a human representative. Even today the lion-share of financial fraud is due to fake corporations, and other non-human owners of money, hiding the identities of their human controllers.

One way to accomplish this “proof-of-humanity” (PoH) is to associate every node with a partial bio identifier, which may be hashed or encrypted, and that will serve as a secret key, Kid. One cross verification solution calls for nodes to frequently identify themselves with their GPS coordinates, to allow near-by nodes to challenge their Id upon a specially developed inspection protocol. Id Challengers/Inspectors will be rewarded. The inspection protocol developed by BitMint will not identify the person, only his or her humanity.

An abuser could register a cluster of close-by fake-nodes, that would cross-verify each other. To prevent this, the network will have a rule that in the event that a node is found fake, then all the nodes it verified are declared fake, and all their money holdings is pooled for community purposes. This will make it too risky for an abuser to build a cluster of fake nodes, and will motivate any bonafide node to counter-verify its verifier.

In order not to surrender identity via the bio-key, the network will allow partial data to be used. The early registrants will identify themselves with very little bio data. Later joiners will find in the general ledger that a previous node shared their same partial bio identification data, and then will add some more data for distinction. So gradually later and later joiners will have to surrender more bio data so that each node remains unique. But still even late joiners will surrender only very partial data, and keep their privacy in tact. Securing the humanity of nodes will allow for easing up some power-sharing protocols, and revitalize proof-of-work and proof-of-stake, etc.

The detailed solution proves quite complicated, so partners are welcome! (gideon@BitMint.com).

SatoshiPay phases out Bitcoin, partners with IOTA Foundation

PRESS RELEASE: IOTA

SatoshiPay, a blockchain-based nanopayments company that enables digital transactions on a micro-scale, today announced its partnership with the IOTA Foundation to explore replacing Bitcoin with IOTA as the company’s settlement network.

17 July 2017

Since its 2015 product launch SatoshiPay relied on the Bitcoin network to settle nanopayments. Initially Bitcoin transaction fees were negligible at below €0.01 per transaction of any amount. Due to Bitcoin’s rising popularity in 2017, combined with stalling scalability improvements, the network’s transaction limit regularly gets hit, leading to congestions and fees rising to uneconomical levels.

To sustain its business model based on frequent low-value payments, SatoshiPay is seeking to replace Bitcoin with a much more suitable distributed ledger technology.

SatoshiPay CEO Meinhard Benn said: “We love Bitcoin for its pioneering role in the creation of our industry, but some blockchain networks it inspired have evolved faster than Bitcoin itself, so we decided to move on to superior technology.”

The IOTA network, with its token listed as 8th largest cryptocurrency on coinmarketcap.com at a market cap of €460m, offers zero-fee transactions and does not limit the number of transactions per second, making it unique among cryptocurrencies and an ideal ledger technology for SatoshiPay’s future needs.

The IOTA Foundation and SatoshiPay agreed to work on a proof-of-concept project supported by the IOTA Ecosystem Fund, combining SatoshiPay’s frictionless content payment interface with IOTA’s scalable ledger technology.

The results of the joint proof-of-concept are expected to be presented in August 2017. Users of the upcoming project website will be given free IOTA tokens to try out instant payments for digital content like videos, images or downloads.

While corporates such as Innogy, Canonical, Bosch, Cisco and Microsoft are building IOTA prototypes focussed on the Internet of things, SatoshiPay is the IOTA Foundation’s first partner to build a purely web-based application.

“Working with the IOTA Foundation allows us to explore bleeding edge technology with a clear focus on massive scalability. We couldn’t be more excited and expect plenty of exposure and new opportunities to open up” said Benn.
David Sønstebø, founder IOTA Foundation commented: “SatoshiPay pioneered the micropayment business model, while IOTA supplies the technology that makes it a reality, therefore this collaboration is a natural fit.”

物聯網世界的基石-信任(二)

物聯網世界的基石 — 信任(一)

在上一篇的最後,我認為區塊鏈技術可能是 New Internet的基石。

去談一個New Internet可能會過於巨大,重新聚焦回萬物聯網的影響。

我們來看看萬物聯網的物聯網會有哪些特徵?

  • 低功耗
  • 需要廣泛的互通性(Interoperability)
  • 百億數量級的交易數量
  • 資料正確性

而在前一篇提到所謂New Internet的基石可能是區塊鏈有關的技術。

我這邊沒講就是區塊鏈而是跟區塊鏈有關的技術是有原因的。

現行的區塊鏈極有可能都只是通往未來的過渡,但從現在的參與確實有意義的

以我的技術合夥人Jim所整理的筆記來分類目前的區塊鏈技術

  • Generation 1.0 — Bitcoin and all the clones of it, i.e. Ethereum. [Blockchain with PoW]
  • Generation 2.0 — Peercoin, Ripple, NXT and all the clones of them. [Blockchain with PoS] — includes Ethereum if they switch to PoS one day.
  • Generation 3.0 — Simcoin, RaiBlocks, DAG-based coins, etc. [PoS without blockchain] — can include weird experiments, like eMunie, here too.

我們可以觀察到到了不久的未來,所謂的第三代區塊鏈技術是否還能叫做區塊鏈已經很難說,因為拿掉了”區塊”也拿掉了”鏈”。而更回歸是分散式帳本(Distributed Ledger)的技術。

從設計的角度來看

  • Generation 1.0 is proven to be viable, yet inevitably leading to centralization.
  • Generation 2.0 is in the process of being proved, and we already see difficulties with PoS, like Ripple’s consensus issues.
  • Generation 3.0 is not even technically working yet. It is at the proof-of-concept stage.

這演化就等於是從PoW -> PoS -> without Blockchain

區塊鏈的諸多特性包含

  • Decentralized 去中心化
  • Trustless 去信任
  • Collectively Maintain 集體維護
  • Reliable Database 可靠資料庫
  • Open Source 開放原始碼
  • Anonymity 隱私保護
  • Time Stamp 時間戳記
  • Asymmetric cryptography 非對稱加密

都是作為物聯網中物對物的匿名可信任資料交易中非常需要且又能可靠的。但現行區塊鏈為了創造出一個去中心化網路而用來創造”誘因”的”幣”卻也成了B2B企業應用中的困擾。

最好的例子就是作為開宗的Bitcoin,作為理想的去中心化網路示範,中本聰設計了幾近完美的機制,但卻在中國強大的算力之下被逼出了各種極限。

並且原本的全網認證和區塊都成了企業應用中的種種包袱,這樣的包袱在物聯網中真實狀況的資源有限更限制了既有區塊鏈技術的導入。

這時我們發現了一個有趣的技術 IOTA的Tangle

他的關鍵都寫在一開始了,

  • 沒有交易成本
  • 去中心化
  • 可彈性放大使用
  • 模組化(可做離線認證)

這些看似天書的特性用白話來說是什麼呢?

在物聯網中物對物的資料交易往往不是需要競逐算力,而是有其天生的責任,企業內的各種資料交易/交換也是,因此用算力認證的機制變成多餘。

而也因為物對物(M2M)或者企業應用,不需要如比特幣的誘因來建立節點網路。

這些在Tangle中都沒有了。Tangle的具象就像其字

Tangle

具體應用樣貌像什麼呢?

會很像我們生活體驗中的”標會”

我跟A借100萬,在實際的樣貌中,是否有需要搞到全世界幫我們記錄?似乎是太過小題大做,但究竟該多少人來幫忙作證呢?是同一個辦公室的人?還是同時在大安區的人,抑或是整個台北市?這部份就是IOTA的工作小組正在設計的邏輯。

其結構跟現行的網路更為接近,是一個網的概念,沒有區塊也沒有鏈也讓他的擴充性會更好處理。

有趣的是,IOTA的創辦人跟Ethereum的創辦人一樣都是二十歲出頭的年輕小伙子,等於證明了能夠顛覆未來的真的是年輕人所創造的一般。

回到區塊鏈帶來的價值,有些書會說這是讓過往儘是資訊交流的Internet變成價值可以轉移的技術。

透過各種區塊鏈技術,讓數位科技真正的成為與實體世界同步成為可能性,也就是真的達成了價值的轉移。

白話來說,過去我分享給你一首音樂,基本上就是我copy給你,你有我也有,於是例如Apple或者Spotify都在解決這一類的問題,於是創造了自己的封閉生態圈來達成這樣保護音樂資產的體驗。但這還是建構在其封閉生態圈內的。透過區塊鏈技術,就真的可以做到我分享一首歌給你,那其定義是

  1. 我借給你一段期間
  2. 我送給你

這兩個的真實意義就是你有的時候我是不會同時擁有的,這是實體世界擁有的特性,在過去的資訊網路世界中無法呈現這樣的特性也限制了數位世界的價值。透過區塊鏈技術等於同步了實體以及數位世界。

透過其可做匿名信任交易的特性,也會成為諸多物對物的物聯網世界安全交易的基礎。這也已經可以在幾個形成中的物聯網國際標準中見到蹤跡。

回應標題,為何會說物聯網世界的基石是”信任”?

因為我認為若萬物聯網的New Internet是個會發生的必然性,那麼解決萬物聯網的各種基礎架構勢必得重新思考而非用過去的網路樣貌來設計,繼續用過去的方法簡單說,只是讓本來的網路巨頭掌握優勢進而大者恆大。反而去思考在其巨大中心化的作用力之下會產生的反作用力必然是新機會之所在。

The Transparency Compendium

Preamble

Everything in this blog post has been public knowledge from day 1, but now that we are welcoming thousands of new people into the ecosystem it is a good time to summarize and elucidate each of these topics individually in one place. This makes it easy for new members to understand the technology and the current status of IOTA, as well as mitigate the wave of misinformation that inevitably arise whenever cutting edge projects go public.

Basics

Let’s begin with the common sense, IOTA’s Tangle is a significant leap forward from blockchain, which itself is still very much experimental tech, something that need to be highlighted and reiterated. Even though we now deem the software ready for the public to experiment and develop with, it has to be noted that IOTA is still beta software in continuous production, like all other public distributed ledgers at the moment. We are getting closer and closer every hour to a production ready version, and are already in conversation with standardization bodies about the ultimate goal of making it a standard, and beyond that be deployed in large scale ecosystems internationally. However, it’s important to still keep in mind for the time being that one has to take the necessary considerations into account and use precaution when utilizing it for anything critical at the moment. In short: use common sense.

Maturity

The IOTA client is currently available in a Java implementation, which is pretty much the equivalent of a ‘minimum viable prototype’, but work has commenced on a fully optimized C++ and Rust client, with more clients planned. Likewise the libraries are growing consistently and we have a lot of them on our roadmap. Likewise the vault of tutorials is continuously being expanded. There’s also a lot of cool tools being developed by the community. Finally it has to be emphasized that IOTA is an open source project, currently there are millions of dollars to collect by participating in all of the above. As with all software there are also still some bugs to be ironed out, and quite nice compensation for doing so. While the IOTA core and ecosystem is growing exponentially it is still very much in an early phase.

Coordinator = Temporary training wheels

Coordinator

IOTA is currently in what should be considered a ‘transition period’ towards large scale deployment and standardization. Like Bitcoin, Ethereum and all other distributed consensus protocols before it, the IOTA network need an onboarding mechanism to provide 34% attack protection in its early days. Due to the unique underlying architecture of IOTA this takes the shape of a ‘Coordinator’. The ‘Coordinator’ or ‘Coo’ for short, is essentially training wheels for the network until the amount of organic activity on the ledger is sufficient to where it can evolve unassisted, at which point the Coo is permanently shut off. This does not mean that the IOTA ledger is currently in any way centralized, the network is 100% decentralized, every node verifies that the Coo is is not breaking consensus rules by creating iotas out of thin air or approving double-spendings. In fact any talented programmer could replace Coo logic in IRI with Random Walk Monte Carlo logic and go without its milestones right now, so technically even at present the Coo is entirely optional. The only role the Coordinator serves is to protect against attacks in this temporary infancy stage of the Tangle ledger, if we shut the Coo down the network would continue to evolve as it will in the future when it is unassisted by these ‘training wheels’.

Curl

As IOTA was the first distributed ledger project that took the inevitable threat of scalable quantum computers seriously, we had to move away from standard elliptic curve cryptography. A few months later NSA validated our concerns by announcing official concern over the ‘quantum threat’. Since then there has been numerous quantum leaps in quantum computing, further validating this engineering decision we made. Beyond this concern we also had to follow a path that is optimized for the future landscape of Internet of Things. Curl is a new kind of hash function optimized precisely for these two things, it is based on well-studied sponge construction invented by the Keccak creators (SHA-3) and strictly conforms to all requirements described in their official paper. Though Curl has gone through reviews, it is naturally not as explored as older ones yet. Curl, like the rest of IOTA, is continuously being audited by more and more cryptographers and security experts.

Hardening the software with hardware

Hardware support

Even though IOTA works great and scales better than any other public distributed ledger already, in order for IOTA’s full vision and true potential to become a reality a ‘Curl hasher’ will need to become a standard component in CPUs deployed in IoT environments. In fact a specialized CPU for IoT and Distributed Computing was the precursor to IOTA. This is a trivial matter, just like Floating Point Units/math coprocessors was made a standard part of all CPUs in the 1990s once the demand for math intensive operations became a norm. Another example of this sort of hardware support being standardized due to software demand are integrated GPUs in phones once the UX/UI and increased game complexity demanded it. It’s the same thing here, as IoT grows and the demand for the distributed ledger technology increase, it will simply become ‘just another’ component in the tech stack, subsequently hardware will simply adapt to accommodate the new status uo, in fact this is already occurring.
This means that even small devices in the Fog/Edge of the network will be fully capable of carrying out their own hashing for hundreds/thousands of transactions per second locally without the need to outsource it. With hardware support the fundamental limit of IOTA’s scaling will be the laws of physics themselves. I.E how fast radio waves/photons can communicate data. It’s important to note that this hardware component does not add any extra cost either in price or size of the chip to the manufacturer and will be entirely open source.

In the comment section there will be some FAQs and community written elucidations on common misconceptions of IOTA.

Exchanges Bitfinex and BTC-e Under DDOS Attacks, As a Result Bitcoin Price Falls to $2424

Leading bitcoin exchanges report that they have suffered from cyberattacks this week.

On Monday, BTC-e exchange said its systems were attacked, which resulted in the website temporarily going down. The news was announced in the tweet that was later deleted and the website showed trades going through.

The next exchange that appeared under the threat is Bitfinex that yesterday informed about distributed denial-of-service attacks, or DDoS, that attempted to paralyze the system with a flood of information.

The attack followed a similar one occurred on Tuesday morning. Bitfinex needed one hour to solve the problem and the exchange returned to regular operation.

Chris Burniske, blockchain products lead at ARK Investments, explained that the attacks are “not surprising” taking into account the bull cryptocurrency market. “There’s a big difference between a denial of service attack, and a hack that causes clients to lose funds,” he said. “As of yet, we’re fortunately not seeing any of the latter.”

Indeed, we currently observe unprecedented boost of investor interest and record-breaking levels of fundraising for new cryptocurrencies. Experts are concerned that the largely unregulated cryptocurrency industry might not be able to manage the hype.

“Investors with assets on centralized cryptocurrency exchanges should be careful. The track records of these organizations are not good, and as the assets on the exchanges grow, so does the bounty for attacking or hacking them,” said Benjamin Roberts, co-founder and CEO of Citizen Hex, a digital currency trading start-up backed by three Canadian venture funds.

Roberts as well as other digital currency analysts warn that cyberattacks can allow the attackers to manipulate the bitcoin market. Since several major exchanges located around the globe set the bitcoin price, temporary disruption of a single exchange can allow a trader to take advantage of price differences.

Bitcoin immediately reacted to the attacks with its price falling by 12% to $2,424. Looking back on the beginning of June, the price was approaching $3,000.

The second popular cryptocurrency, Ethereum, has surged several thousand percent in that time.

“A speculative frenzy is never a good thing. I don’t think we’re there right yet,” Adam White, Coinbase vice president and general manager of its GDAX exchange, told CNBC in a phone interview. But “I do think the ICO or token generation events have … maybe a bit too much enthusiasm for them.”

When Bitfinex officially announced the IOTA token the other day, the transaction volume skyrocketed so that the servers briefly went down. “Moments after the IOTA launch,” Bitfinex representative Brandon Carps shared, “we were all hands on deck to load balance and ensure IOTA trading was back online and operating as expected.”

Remarkably, 4.44 Million Mega IOTA was traded with the IOT/USD pair only for the first three hours of trading. Even greater activity was observed in the IOT/BTC trades – 11.67 Million Mega IOTA was traded for the same time period.

Exchange launch

The day is near

Another milestone is approaching. Ever since we publicly announced the IOTA project back in 2015 we have been bombarded with requests by thousands and thousands of people urging us to list IOTA on exchanges, to which our default response has always simply been: “When technology is ready”. While we have always been happy to see the enthusiasm and confidence expressed by these people, IOTA is above all an open source project initiated for and entirely focused on enabling future applications, security, services, infrastructure, business models, governance structures and beyond. When revolutionizing already revolutionizing technology (Blockchain), patience is more than just a virtue, it’s a prerequisite to succeeding.

We have been in active dialog with numerous exchanges, some stretching back to late 2015, big and small, old and new, in diverse geographical regions, and all of them have been very professional and supportive in respecting IOTA’s unique approach to listing and our vision of meticulously ensuring that the technology and ecosystem takes priority before market cap and opening IOTA to the free market of exchanges.

With that being said, exchanges and the market plays a pivotal role in realizing the ambitions of the IOTA project, it strengthens the value and liquidity of iota tokens, which is necessary for the Machine Economy to function, and it also opens the doors of IOTA to a whole new audience…

The doors are opening

For thousands of people this is the first encounter with IOTA, to those we extend a warm welcome. The technology is now sufficiently matured to the point we are confident that we can go on exchanges and welcome thousands of new users. This marks the beginning of a new and exciting chapter in this book we as a community are collectively penning. That being said, IOTA is still going to go through iterations and optimization in the following weeks and months until the core protocol is ready for standardization and prime time deployment in the real world on a large scale. Perfection takes time.

Get your tickets and join us on this epic journey

Each individual exchange will make their own announcements of IOTA exchange listing timelines and plans, but the first exchanges will start listing IOTA on the 13th of June!

If you represent an exchange and want to begin the listing process, then contact us at exchanges@iota.org for further assistance and documentation. If you are a user/trader that want to see IOTA on your favorite exchange, forward them this post.

Blockchain @ Berkeley + IOTA

The IOTA Foundation is excited to welcome Blockchain @ Berkeley into the community and to announce our official collaboration. B@B is an organization setup by students at UC Berkeley. Their group consist of Berkeley students, alumni, community members, and Distributed Ledger Technology/Blockchain enthusiasts from all educational and industrial backgrounds: Electrical Engineering and Computer Science, Economics, Business, and more. Over the coming months we will be exploring several different use cases in a multitude of sectors together with this great team. Read below about each individual member’s experience, interest and reason for wanting to work on IOTA in their own words.

Jonathan Allen

I am the Co-Head of Consulting at B@B. I was in the military for five years as an Explosive Ordnance Disposal Technician, then worked at several tech startups before starting school at UC Berkeley last semester. I am an Interdisciplinary Studies major with a focus in economics, business, and computer science. I have been closely following the blockchain space since late 2013 and I am an avid physical crypto collector.
I am very excited to work with IOTA. When I first read the white paper I was extremely impressed with how it took such a novel approach to solving the issue of transaction throughput seen on other current distributed ledger implementations. Many of the use cases I have been explored make much more sense with feeless transactions and no hard cap on transaction rate. Looking at the development road map it is extremely ambitious and we can’t wait to get involved in any way that we can.

Collin Chin

I am a student developer at B@B and a third year electrical engineering and computer science major at UC Berkeley. Last semester, I worked as a developer for B@B’s external consulting team on a project with Airbus Group. This Summer, I am interning at Consensys with the Gnosis team.
The very first in-depth blockchain project that I worked on attempted to solve problems using IoT devices. However, deeper thought into connecting small devices to a large blockchain network poked holes in the use-case. With IOTA’s scalable Tangle, I can see many of the difficulties involving IoT and blockchain disappearing. This realization, along with the motivated IOTA community, has sparked my interest in developing on IOTA and made me excited for our new partnership.

Raymond Chu

I am a third year computer science major at UC Berkeley and developer at Blockchain at Berkeley. Last semester, I was the lead developer on the Provenance team — supply chain management of pharmaceuticals to comply with the FDA’s new Drug Supply Chain Security Act (DSCSA). This summer I am a software engineering intern at IBM and I’m currently seeking more opportunities and projects in the blockchain space.
I am really looking forward to working with IOTA because of the potential use cases that IOTA’s tangle brings to the table. Many of the current blockchain implementations don’t have the scalability or practicality, while IOTA opens many doors. I’m excited to see and work on the innovative ideas that spring from the IOTA community.

Sunny Aggarwal

I am the Head of R&D at B@B and am a 3rd year “Electrical engineering & Computer Science” and Political Economics student. I have co-taught the Cryptocurrency Decal at UC Berkeley for two semesters and will be teaching an Ethereum Dapp Development course in Fall 2017. I have worked on a number of blockchain projects including a novel consensus protocol Proof of Luck, a social contract bond platform BlockChange, and decentralized Blackjack platform BlockJack. I also have contributed to some open source projects such as BlockStack and the IPFS Python Api. This summer I am interning with Consensys on the Alethio team.
I have described IOTA to many as Blockchain 3.0. The Tangle is quite revolutionary and is a brilliant solution to many of the scaling troubles that other traditional blockchains are facing or will come to face. A few months ago I read through the Iota Tangle Whitepaper and was so impressed I delivered a presentation on it to the B@B organization. You can watch it here. I am excited about the new use cases that will open up in a feeless market and look forward to helping push forward the next revolution in Blockchain tech.

Pranav Gaddamadugu

I am a developer at Blockchain at Berkeley and a second year computer science major. Last semester, I was the lead developer on the Blockjack team, where we implemented a version of Blackjack on the Ethereum blockchain. I am currently interning at Consensys with the Virtue Poker team.

I look forward to tackling interesting use cases for IOT and the blockchain. IOTA offers a large number of advancements, like quantum-proofing and eliminating transaction fees, that enable a variety of implementations. Although the projects are ambitious, I am excited to see what the IOTA community can come up with.

Ali Mousa

I’m a second year computer science student at UC Berkeley. Last semester, I was a lead developer on Blockchain at Berkeley’s first external consulting project for the Airbus Group. This summer I am interning at BlockApps.
IOTA excites me because a fee-less, scalable blockchain is what the blockchain space currently lacks. This enables many use cases that other platforms render impossible because of gas costs and high transactions fees, as well as high block times and absurdly lengthy times for transaction finality. IOTA also brings the blockchain to more devices than just ASIC miners and beefy computers with thousand dollar GPUs. IOTA has the potential to be the next generation blockchain.

Gillian Chu

I’m a second year computer science student at UC Berkeley, with a minor in Biology. Last semester, I worked on the consultant team to the Airbus group, and now I’m an editor for the Blockchain @ Berkeley blog, as well as helping to organize the October 2017 Cryptoeconomics conference. I’ve worked with B@B for a full year now and am excited about how I’ve seen the space grow in this short span of time.
IOTA’s Tangle resolves scalability obstacles in a way that gives blockchain the brilliant potential to truly affect a variety of contexts. I’m especially fascinated by the use case where IOTA’s data validators push telehealth forward. Additionally, with feeless transactions, IOTA’s role in developing an e-voting platform seems particularly promising. With so many impressive and ambitious use cases made possible, I’m excited to learn lots in our partnership.

Nick Zoghb

I’m a developer, consultant and education officer for B@B. I am also a third year computer science and bioengineering major. Last semester I worked on an enterprise-facing platform that leverages IoT and Blockchain technologies to mitigate supply chain inefficiencies within the agricultural industry. I am currently co-heading our initiative to create a developer-focused ethereum course.
My time on the IoT team has convinced me of the vast untapped potential still latent in the tech. IOTA is leading the way through new and exciting territory with the potential to upend, not just entire industries, but how the economy itself functions. The partnership is no doubt a thrilling next page in B@B’s book; I am looking forward to learning and being an effective contributor to the team.

Ronen Kirsh

I am the Co-Head of Consulting at B@B and in charge of external outreach. I served in the IDF for three years in a special forces reconnaissance unit as a medic, commander, and sergeant. After the military, I co-founded two startups in the social entrepreneurship space and worked in sales and marketing in the foreign exchange industry. In 2014, I moved to California to pursue my higher education and I am currently a senior at UC Berkeley studying Economics and Entrepreneurship. I have been engaged in the crypto space for almost two years and I have been hooked ever since.
Since hearing about IOTA’s novel approach to scalability and emphasis on IoT use cases, I have been waiting a long time to see the first implementations of the technology. Being early adopters is a core value at B@B and provides us with the passion and drive to become a leading contributor within the IOTA community. We can’t wait to contribute to the ecosystem of support and development in order to help IOTA’s goals come to fruition.

William Dai

I am a developer and consultancy management officer at Blockchain at Berkeley. As a second year electrical engineering computer science and business administration intended double major at UC Berkeley, I am inclined to view both technology and finance not as means to an end, but tools for creating a more equitable world where people have the opportunity and resources to choose their own destinies. During the last semester, I worked on a project exploring the feasibility of cross-exchange arbitrage between fiat currencies and the two leading cryptocurrencies, Bitcoin and Ether. This summer, I am taking two courses, on project management and machine structures, as well as serving as a residential advisor and working on a project with Augur. In my free time I enjoy participating in CTFs (Capture the Flag, a genre of cyber security competition).
I am particularly fascinated by IOTA’s groundbreaking advances in secure data transfer. The idea of IoT devices seamlessly conducting microtransactions opens a multitude of possibilities for more efficient automation or even crowdsourcing. I look forward to learning while collaborating with IOTA.

Cliff H. Ahn

I am a consultancy management officer at B@B studying economics and am planning to take courses in computer science to possibly pursue a minor. Last semester, I was the head of consulting for a project that focused on an enterprise-facing platform that leveraged IoT and Blockchain technologies to mitigate supply chain inefficiencies within the agricultural industry with Nick Zoghb. I worked with some fintech students to educate and prepare a presentation to USAID regarding blockchain technologies, and am currently working on projects within the organization.
After working on a project focused on IoT and blockchain, it felt natural to move towards IOTA after it was introduced to us. IOTA’s scalability as well as its focus on IoT combined with the many ambitious projects that are in the pipeline are what drew me in, and I am excited for the opportunity to learn and grow alongside my peers and IOTA.

Aparna Krishnan

I am a third year Computer Science Major at UC Berkeley with a minor in Economics. I co-head the Education Department and co-taught the cryptocurrency decal in spring 2017. I am currently working on my own series of blog posts analyzing the corrective security measures of blockchain technologies.
After reading a paper about how users’ data is not their own, I’ve been very keen to work on an application where people can monetize and control their own data. I believe that such user data can easily be monetized with IOTA’s tangle because it enables micro transactions. I am excited to work IOTA’s motivated community and push forward some interesting projects!

The IOTA Foundation is very excited to have such great students working together with us on a myriad of interesting projects that will explore uncharted territory for distributed ledger technology. Expect a lot of cool use cases and projects to spawn from this. Welcome B@B!

IOTA as the secure backbone of electronic Voting

IOTA is being explored by researchers over at the University of Lancaster after receiving a EPSRC research grant. This effort also got Cybernetica, the company that introduced legally enforceable eVoting to the world in 2005 on board.

Stresstests

We have been conducting numerous different stresstests lately to demonstrate and confirm the scalability capability of IOTA. So far we have achieved a higher throughput than any other public distributed ledger in history. A full report, as well as a much larger stresstest in collaboration with 2 large corporates will take place soon to truly highlight just how well IOTA truly scales.

New Public Testnet & Bug Bounty

We are happy to announce that, as we are nearing IOTA’s official launch on exchanges, we are opening up a new public testnet together with a bug bounty program. Over the past months we’ve been working on refactoring and further optimizing IRI, to prepare it for larger stresstests (as you might have seen here), private deployments for corporates and an official rollout on our mainnet.

To further battletest the software after our completed security audit, we want to make it possible for the public to participate and try out the new IOTA software for the first time. In order to incentivize active participation, we’ve set out an open bug bounty program that is aimed at non-technical testers, but also developers which more thoroughly review IRI.

In addition to IRI, we will also include iota.lib.js and the GUI Wallet into this program. A special version of the GUI Wallet, specifically for the testnet, will be prepared and released beforehand.

As seen in the picture above, we have a 3 tiered reward program, with the starting payout being $50, going up to $5000 for more severe bugs. We might also hand out some rewards for really active participants during the testnet.

In order for a “Severe Bug” to be paid out, the person submitting the bug also has to provide some more direct indication on where he / she thinks the issue lies and how it could be fixed.

We will pay significantly more for serious bugs that are reported. Those will be reviewed and taken care of by the entire team and discussed with you.

All rewards will be paid out at a fixed market cap of $200m.

When it will start

The public testnet will officially begin on Wednesday 10th May 2017 at around 8PM CET. We will be running the bug bounty program and testnet even after the exchange launch, so we can assume that it will run indefinitely (as long as no major problems arise). Before we begin with the testnet, we already invite participants to the #testnet channel on our Slack where this entire operation will be coordinated from.

We will provide further instructions to everyone on Wednesday.

Meet IOTA Graphic Designer Sabri Goldberg

Sabri Goldberg (also known as “Kalipo”) is a passionate designer. From his early childhood he was enthralled with drawing. At the age of thirteen, he purchased his first version of Photoshop CS by saving money from delivering a myriad of newspapers. This event ended up sparking a realization that his future professional direction would be pursued in the field of Graphic Design. During his Communication Design studies at HTGW Konstanz, he deployed his first online store. This marked his first step in the direction towards cryptocurrency / distributed ledger technology. In 2012, he discovered Bitcoin while searching for alternatives to Paypal. He spiraled into this space, and it eventually led him to the discovery of Nxt in 2013. He supported Nxt by designing a complete revision of the project’s Corporate Identity. Before joining IOTA full time Sabri has been a vital designer for numerous multi-million dollar blockchain projects.
His fervor for graphics is still ignited as it was in his early childhood. With his creativity and brilliant design capabilities, he is committed to being a valuable asset to IOTA.

His beautiful work in IOTA can already be seen in the IOTA Roadmap and IOTA Ecosystem Fund.

Sabri on joining IOTA

IOTA to me, is truly the first cryptocurrency/DLT which has the real potential to be employed in the world for daily life. This technology has taken all the weaknesses of Bitcoin and others, and transformatively reinvented the underlying principles and turn these into strengths. IOTA mirrors the type of vision that I expect to see become reality in the future. I look forward to contributing to this brilliance.

Announcement: IOTA as backbone in e-Voting research

A new research project lead by the cryptographer Dr. Bingsheng Zhang at the University of Lancaster will utilize the public distributed ledger of IOTA as backbone for its novel ambition of an end-to-end verifiable electronic voting bulletin board on top of a secure and tamper proof decentralized architecture.

A participant and advisor to the research effort is the pioneering company Cybernetica AS from Estonia. The company is recognized around the world for its seminal role in the field of offering voting over the Internet. Cybernetica enabled Estonia to become the world’s first nation to hold legally binding general elections in municipalities over the Internet since 2005, and again the world’s first parliamentary elections since 2007. Their immense experience and expertise will be of great importance for advising on this project.

The IOTA Foundation will assist Bingsheng and his team with issues pertaining to implementation of the IOTA ledger and its modules in this research initiative. Members of the IOTA Foundation have a rich history of leading the way of utilizing Distributed Ledger Technology(DLT) in the realm of voting. Nxt’s Voting implementation developed in 2013 was the world’s first voting implementation on blockchain in general, and PublicVotes in 2015 was the first voting implementation on the Ethereum blockchain. We are happy to be part of and assist this project to bring e-Voting to the cutting edge of DLT by going beyond blockchain through IOTA’s Tangle ledger.

About the recently granted research project, which is slated to begin its research officially in July professor Bingsheng Zhang said the following:

The state-of-the-art e-voting systems, such as DEMOS, can achieve end-to-end verifiability in the standard model, but those systems can only support basic vote tally schemes due to its technical limitation — homomorphic tally. This project aims to develop an end-to-end verifiable e-voting system that is able to support rich ballot structures and all known voting/tally schemes, including liquid democracy. The technology and infrastructure developed by IOTA will play an important role in the resulting system, which can facilitate both vote collection and universal audibility during an e-voting process.

Meet core developer Alfred Keller

Alfred Keller is an experimental scientist and sysadmin with decades of professional experience. His IT career started in the banking industry where he was engaged in planning, sizing and testing the future system and network architecture. Later he became partner in a medium-sized company that developed software and devices for access control, biometric identification and the integration of advanced unified messaging systems.
With good knowledge in C, C++, Java and Javascript he is very well prepared to review and test the IOTA core software and artifacts. He has profound experience in data communication and cloud computing.

Master’s Degree in Civil Engineering at ETH [Swiss Federal Institute of Technology Zurich]. Continuously trained on the job in information technology from the very start of Linux back in the nineties up until now.

On why Alfred joined IOTA

Curiosity and thirst for knowledge were the reasons why I started self-studying the blockchain technology in summer of 2016. IOTA caught my interest because it is so obvious that it overcomes the limitations of the traditional blockchain technology. The concept of IOTA as the scalable backbone of IOT, decentralized and without fees, is very appealing to an open-minded engineer with an up-to-date background in distributed computing and embedded devices. And most important: it is open source and allows any organization or business unit to run its own nodes on their own infrastructure. It is even possible to run private ledgers. For a fellow technology whiz, the sky appears to be the limit with IOTA.

Meet core developer Alon Elmaliah

It’s time to officially present the core developers of IOTA to the larger crowd. First up is Alon Elmaliah. He is a programmer and engineer with great passion for security and cryptography,

After several years in the semiconductors industry, most recently at Intel, Alon devotes his time to the study of distributed, decentralized systems & digital cash alternatives; bringing large scale problem-solving skills to software implementations.
With strong background in education & technology, Alon is an active member of the Cryptocurrency scene in Tel Aviv.
Skilled in Python, Computer Science, and C++, he joins the IOTA core development team to push IOTA even further.

B.Sc. in Computer Science & Electronic Engineering from Tel Aviv University
- Curious, loves to research & master new skills.

On why he joined IOTA

IOTA solves traditional cryptocurrency’s principal-agent problem (buyer-merchant-miner) in an elegant way; by removing “mining” altogether, a vast surface of attack & manipulation is resolved — as we see unfold in Bitcoin in the past weeks.
Instead, the users of the network are also in-charge of maintaining the network.
IOTA’s fee-less paradigm will be the back-bone of the Internet of Things economy; integrating machine-to-machine payments, boot-strapping decentralized applications & Data integrity — IoT’s future has never looked brighter.
