In the spotlight of my blog today is the decentralized platform for fast and safe development of dApps (decentralized applications). The basis of its work is a chain with a block infrastructure which provides simultaneous access to millions of users. The network consists of one rank, the data is stored on the users' servers. Inside UChain (the name of this project) operates its own system of tokens and a credit passport for each user.

## The problems to be solved API and SDK developers often complain that their applications are too expensive or are hanging for too much time at the promotion stage. This is because the market with specific management bases has resisted a lot of problems: * Commissions that are required to pay to exchanges are very high; * How can you trust each other if you do not know anything about another person? Only based on mutual trust, but so far this is a very weak argument; * Hacking of data which is stored on one server is much easier, so there is often a leak of information even before the release of dApp; * The servers often "fall down", which makes it difficult to work on them. The UChain blockchain will work autonomously on peer-to-peer protocols. Their task is to solve all the problems listed above. Namely UChain project exists to provide round-the-clock access without interruptions, to check each user and to cancel the commission. And if that suits you, you are on the right track over here. ![5а.png](https://cdn.steemitimages.com/DQmTTScBAcAATqVdbjEfNBwaxiPAYbmQ1fFHMBmxcm5L1NT/5%D0%B0.png) ## User's credit passport and security in the system Conducting transactions in one rank will reduce the commission by almost 20%. The only thing is that we will have to wait until the token deposit will be "defrosted", but this will happen quickly. ![6.jpg](https://cdn.steemitimages.com/DQmWBqH9woN1vvFRkYWsXCj4ff9Uj8MEAM4t8nuPx69cW8K/6.jpg) Transactions in the system will be based on smart contracts that provide legality and authenticity. In the chain of trust appears a new tool - credit passport, which will be open to all exchange services. Only after being identified, users will receive an "identity” or credit passport in the system and will be able to make transactions without "freezing" the deposit. We know that blockchain systems guarantee a high level of security when accessing user data. Which is written and distributed in a variety of stores with a private for each user key. So if one store is hacked, this does not mean full access to the information. ![7.jpg](https://cdn.steemitimages.com/DQmV33p3dYUtnZW41AzMnBnMAUH1JBMm3ZR39nh2i6qPJv6/7.jpg) ## RPCA algorithm The main secret "weapon" of UChain will be a consensus mechanism, which is strictly different from the already known proof-of-work (POW), proof-of-stake (POS) and others common mechanisms. Transactions will be carried out 2-3 times faster. The essence of the algorithm is that the nodes will ping each other, defining the leader and synchronizing the database with him. Is it difficult to become a leader? You need to get the highest amount of votes, and it's almost impossible for hackers to do it. ## The mechanism of encryption and smart contracts Data encryption will be performed using the Elliptic Curve Cryptography system, which you can read more about in WhitePaper of UChain. As for smart contracts, several users will participate in their development, through the P2P network. ## The UChain team It was founded in Vancouver, Canada. Although already now offices are open in southeast Asia. The team is called U. B. Group Holding, and there is already a well-known service for the exchange of bicycles – “U-bicycle”. It exists under the leadership of Ian Yu, Grace Min and by the development of Will Zhou, and currently there are more than 30 million registered users. ![8.jpg](https://cdn.steemitimages.com/DQmVN7RZGTtGJJgmbJDcMg3L36WeL7dmQxTyyp1V4c5gyzr/8.jpg) ## Tokens and UChain ICO The platform recognizes two tokens, the main will be UCN, accepted as payment and existing as an investment. The second token is UCP, it gives the holder the right to vote and raises the reputation, but it is not traded during the ICO. That's what I took from official sources - there is no information on ICO on the site, which somehow confuses. No reason in particular, ok: **UCN token is based on Ethereum platform** **Pre-ICO was held from June, 20th till June, 23th** **Price of the token: 1 UCN = 0.0002 ETH** **Amount of tokens per Sale 40%** **Minimal Purchase is 0.5 ETH** **Maximal Purchase is 5 ETH** **Hard Cap 42,000 ETH** So far so good. Where will UChain allocate the tokens? 40% - Token Sale 35% - Ecosystem 15% - Team (vesting for 3 years with a one year cliff) 10% - Company Reserve ## My conclusion The site is provided with little information about the operation of the platform and its technology. I didn't find Open Source on sources such as GitHub and it confuses me. The team is ok but most people I didn't see in another famous blockchain projects, although if you look at the strong advisers (from APEX, Red Pulse, Ledger Capital), your doubt will decrease as well as mine one. And in spite of the fact that some of the blockchain projects can realize some of the opportunities faster, they still have their audience, so whatever is to be will be. Always do your own research before investing.
