Sentinel Protocol (UPP)

ICO Verdict

Sentinel protocol is a security intelligence platform for blockchains (SIPB) to protect valuable crypto assets from hacking and scam attempts. Threat Reputation Database collects risk information in a decentralized, incentive driven fashion, making it possible to have one unified global threat database. S-wallet, a machine learning engine integrated security wallet, leveraging TRDB, enabling its Fraud Detection System on distributed ledgers and identifies malicious transactions. Security is the fundamental layer of any meaningful projects, exchanges and DAPPs. Crytocurrency related hacks have been nothing short of major catastrophy, thankfully here come the Sentinels.

At a Glance

Sentinel Protocol can be described as security intelligence platform for blockchain (SIPB), this includes a wide variety of security features, from anti-theft, malformed transaction prevention, unknown threat prevention, transaction traceability etc. The protocol collects hacking reports, which are then delegated to "The Sentinels", a group of trusted security experts, who confirms the incident and registers the case information to the Threat Reputation Databse (TRDB). The Sentinels are rewarded for participation under the Delegated Proof of Stake (DPOS) model with Sentinel Points (SP), which can later be redeemed for its native currency UPP. Sentinel Protocol also introduces their own S-wallet, a secure wallet with built in machine learning AI, Fraud Detection System (FDS) and built-in security features such as filtering scam addresses and detecting abnormal behavior, leveraging TRDB for always up-to-date threat definitions. Sentinel Protocol utilizes the strength of decentralized and distributed computing, running extensive tests and simulations in their D-Sandbox (Distributed Malware Sandboxing) environment, effectively cutting cost down compared to the traditional expensive dedicated virtual machine environments. Sentinel Protocol can be integrated seamlessly to any client wallets and exchanges, leveraging its collective intelligence to protect users from malicious threats.

Key Security Features

Threat Reputation Database (TRDB)
Those who have used anti-virus softwares for the internet should be familiar with definition files, each commercial virus scanners maintain their own virus/threat database and end-users need to update on a periodic basis for the latest definition. These databases are not only centralized making them more vulnerable to manipulate but more importantly never complete as vendors lack any incentive to collaborate. Sentinel Protocol aims to create a global alliance for threat information exchange, with built-in incentives for each vendor to contribute to the TRDB.
Machine Learning Engine Integrated Security Wallet (S-Wallet)
Sentinel Protocol's secure wallet (S-wallet) is similar to an "antivirus enabled wallet", leveraging collective intelligence harvested by the community and security experts pooled in the TRDB. S-wallets can detect suspicious executions, these can be in the form of blacklisted wallet addresses, scam sites or fradulent activities detected by their Fraud Detection System(FDS), driven by their proprietary machine learning engine. S-wallet also analyzes the threat tendency and history to proactively respond to unknown threats (known as zero-day attacks) that traditional antivirus softwares can't do before the next software update. This is an AI driven engine, continuously learning from the client side Sentinel Wallet to create model behaviors.
Let's create a use case to see how this might work in real life. Say you're about to participate in an ICO, and ICOs these days come with scams by default. There's a telegram DM popped up on your phone, with a contribution address that will expire in 3 min, it's been a busy day that you're not keeping up with the latest update and you are about to FOMO in.
Now when you enter the contribution address into your S-wallet, ready to send the transaction, the send button suddenly turns red with (13 SCAMS REPORTED), you know S-wallet just saved your hard earned(?) ETH.
Distributed Malware Analysis Sandbox (D-Sandbox)
D-Sandbox is similar to traditional sandbox, a test environment (virtual machines) to run unverified programs. In D-Sandbox environment (decentralized nodes), potential threats are submitted and analyzed thoroughly via collective intelligence, at significantly lower costs of computing resources and infinitely scalable.

Real Hacks, Real Solutions

The Sentinel Protocol team has written a wonderful article examining the recent NEM hack, or more precisely Coincheck exchange hack, a massive 523 million NEM coins compromised. The article can be found here So what is the solution to NEM hack and its kind?
'Security' is a big topic, let's examine a few high profile hacks to understand what Sentinel Protocol is capable of and what it isn't.
The Mt.Gox Hack
In 2011, some hacker breached into Mt. Gox auditor's computer and used it to transfer a huge amount of bitcoins to themselves, which were later sold on Mt. Gox itself. This created a huge strain on the market that caused a major crash.
If Fraud Detection System (FDS) was installed to monitor and detect abnormal behavior, it would've been initiated to notify the exchange to take immediate actions to mitigate the hack, eg. halting trades from this specific address to prevent further damages to the order book.
In 2014, Mt.Gox was robbed a whopping $473 million from transaction malleability attack. This protocol level vulnerability isn't something Sentinel Protocols can help prevent, it is more of a system level design security while Sentinels Protocol is an added layer of security.
There are other examples, like the DAO hack caused by recursive requests called on a poorly designed function, or multi-sig vulnerability hack in both Bitfinex and Parity. These type of 'security' issues can't be fixed or prevented by Sentinel Protocol, but during adnormal events, Sentinel Protocol can at the very least alert the affected parties.

Team

The Sentinel Protocol team is stacked with cyber security talents, a connection was apparently made through the company Darktrace that several team members including the foundeCEO worked for. Darktrace is an AI company for cyber security with 620 employees in 32 offices, specializing in machine learning algorithms to detect and respond to cyber-threats across diverse digital environments. We can also see traces of other industry leading cyber security firms including Palo Alto Networks, F5 Networks and Penta Security Systems. The team has complete relevant work history, experiences, as well as established industry connections for the Sentinel Protocol project.
The name Uppsala is named after an old capital of Sweden, where the founder Patrick Kim and co-founder HM Park stayed and conducted some study over blockchain focusing on lightning consensus algorithm, the idea of Sentinel Protocol was also drafted there.

AMA Request: Coinlab

I have some major questions about the Mt. Gox to Coinlab transition process which can be divided into three main areas.
1.) Technology transition 2.) Business transition 3.) Legal transition
Technology transition: Are you guys writing your own code, website, etc. to perform bitcoin exchanges between people? Or are you using Mt. Gox's code? Or is Mt. Gox still hosting the technology side with only the logo change? If you are using Mt. Gox's code I feel like your programmers won't be intimate with all of the code. Remember when Bitcoinica transferred to Intersango? They gave a Ruby website to non-Ruby developers which led to unprecedented chaos. CHAOS. If Mt. Gox is hosting all of the technology side then I imagine there will be problems since the team is split into two different hemispheres. If you are writing your code from scratch it will be untested. What language are you using? Can you describe some of your coding practices? Database? Are you using the Amazon cloud? The cloud is known for going down (Coinbase uses the Amazon cloud and it goes down from time to time. Who knows how Coinbase runs the qt client in the cloud or if they run multiple instances of the qt client to get it to scale.)
Business transition: Mt. Gox has a team of at least four people, and I know they hired some more to handle the volume. What kind of team do you have in place? Will your site still be able to handle Dwolla, bank transfer, etc. types of transactions? Mt. Gox was hacked because the original founder leaked his access to hackers. Will you give access to Mark? How is the GPU processing going or are you pivoting to this new business model? How many businesses can you run at once with the funding that you have? "Wall Street" was mentioned to handle high-net worth individuals. What kind of progress have been made here? Are we talking about a Nasdaq ticker or a fund of some sort?
Legal transition: For verified users, Mt. Gox has all of our documents. How will this be handled? Will you report all trades to the IRS? Or, will you consider Bitcoin a commodity? How do you deal traded coins vs mined coins in terms of taxes? If the gov't has a warrant for info on an individual how will you deal with this? It seems like you would have no choice but to comply with the gov't or risk going to jail. What if the president makes bitcoins illegal (as was done with gold in the 1930s).
Sorry if there are so many questions...because there are. :P

Introducing CryptocoinTicker, a desktop application for Cryptocoin exchanges

After seeing this post about a physical desktop ticker for cryptocurrencies, and seeing that a lot of the requests in that post were for software, not hardware, (and since it's not in direct competition), I decided to post about the program I wrote last weekend.
CryptocoinTicker is a Windows application for showing Cryptocurrency market data, it currently has a candle chart (draggable and scrollable), a Depth chart, automatically updates data from the APIs of exchanges and new exchanges can be easily added as plugins.
Download
Source Code
Screenshot
It currently supports MtGox, BTCe, Kraken, Bitstamp and Vircurex, and for those sites it should support all available currency pairs.
Historical data is saved locally, but due to restrictions in some of the APIs its history data doesn't go too far back on first start.
I first posted about it on the Litecoin subreddit 2 days ago.
I hope it helps some of you guys :)

Just released an open source Java library for interacting with Bitcoin exchange APIs and want to get the word out.

The project is called XChange and the code can be found on Github. So far it provides support for:
We plan on adding MtGox streaming public market data and private account data next, followed by Intersango, and InteractiveBrokers, a traditional financial broker of stocks, forex, etc. See Milestones for more details. Someone left a feature request today, asking for hooks into the Bitcoin Charts Ticker API, which we'll probably add soon.
XChange has already been integrated into Multibit, showing near-real-time ticker data from MtGox directly in the client.
Any criticisms/thoughts?

Bit Notifier 1.4 is out - adds currency selection

Earlier this year I started messing around with a desktop ticker. /Bitcoin seemed to enjoy previous versions, so I thought I'd let you know about the new one.
What is it? A desktop price ticker that displays market data from Mt Gox. It'll provide the last price, high, low, average, current ask, and current bid in an application window, on a system-tray icon, and on Logitech keyboard LCDs (G510, G15, and G19).
What's new? Support for every currency Mt Gox trades in, including USD, Euro, GBP, Yen, AUD, and NZD. You can pick your currency in About->Settings. There were some fairly significant changes in the source, if that's your thing. See the github for more information on that.
What are the requirements? .NET 4.5 (should be included), Windows, and an internet connection.
Where's the source code? On GitHub
Where's the exe? On BilldLabs
I want it to do X, Y, and Z! Leave a comment here, on the billdlabs blog, or PM me. Many of the things that appear in the current build are requests from users. I'd like to continue that tradition. Adding additional exchanges is already on my agenda.

How much "Lag" is acceptable? - Mt. Gox lag ranging from 2 - 100+secs.

I have just been watching the ticker for a few minutes and am noticing trading engine lags up to 30 seconds. I am sure they can even go way higher. However, in an recent article posted here I read, "The lag of six or seven seconds before a trade is executed "is not acceptable," said Gonzague Gay-Bouchery, marketing for Mt. Gox, in a phone interview."
So can someone give a quick overview of what "lag" actually is and how bad it is for the market.

Does anyone have sounds from clarkmoody when Mt.Gox was still around?

I am trying to make my own ticker for bitstamp that will differ buys from sells. I started trading in Mt.Gox era, and I got adapted to that ticker from
http://bitcoin.clarkmoody.com/ticke but now when I open it, it just goes to that new webpage that does not have sounds. I am writing it in java, and I am willing to share code/compiled product with you guys when I'm done if anyone else is interested in such program.
If you don't have those beeps, could you guys recommend me some good buy/sell sounds, that are not oppressive, and that stack well (when 2 orders go at similar time, so that it still sounds good)

The currency ticker used for bitcoin is either BTC or XBT. KEY TAKEAWAYS. A bitcoin exchange acts as the intermediary between a seller and a buyer or, to use cryptocurrency language, between a “maker” and a “taker.”A bitcoin exchange works like a brokerage, and you can deposit money via bank transfer, wire, and other common means of deposit. Now in version 2, you must simply add before your post data the relative path you are requesting (anything after the /api/2/ base, ie: BTCUSD/money/ticker), concatenated with a NUL character (ASCII code 0). So the signature is now made starting from your relative path + NUL character + post data (which must include your nonce!). fast ticker 2014-03-20: 当社保有ビットコインの残高に関するお知らせ / Announcement regarding the balance of Bitcoin held by the company; 2014-03-14: 米国連邦破産法第15章適用の申請に関するお知らせ / Announcement regarding the applicability of US Bankruptcy Code Chapter 15 In the past we have seen with the Mt.
