As we all know that blockchain is a peer to peer system, protected by an encrypted PoW algorithm, and designed by mysterious Nakamoto.
Sidechain is Bitcoin’s most anticipated technology for its improvement. Once it is deployed, its function is almost unlimited, and it is an important condition for achieving million-level TPS.
Some media reported that Ulord uses multi-sidechain technology and the parallel accounting mode, and it can reach TPS linear increase. The million-level TPS proposed by EOS may be realized by the Ulord public blockchain first.
Ulord has launched USC sidechain compatible Ethereum Virtual Machine (EVM) compatible with the USC, and will launch the UOS sidechain.
This article will introduces the UOS mechanism, its functions and advantages.
1. What is sidechain?
To understand UOS, first you need to know what is sidechain.
Sidechain is a complement to the mainnet. In the world of blockchain, the limited volume of the block limites its function. Like Bitcoin, it provides us with reliable transfer plan with a low speed. How to solve the problem?
Therefore, sidechain is born!
Just as Ulord, the mainnet is like a main road, and the sidechain is like auxiliary overpass. It improves the traffic efficiency. Sidechain is a solution for improving the performance and scalability.
2. What is UOS?
It can quickly establish a blockchain landing application, which is friendly to both ordinary users and developers.
UOS is a Ulord sidechain, it will not release new tokens. All the coins in the UOS chain will be generated after the mainnet (Ulord chain) initiates the transaction, which will not appear or disappear occasionally. The exchange ratio between UOS and UT is 1:1. UOS fundamentally reduces the barriers to enter the blockchain technology and the cost of trial and error, and help the blockchain entrepreneurial project develop quickly.
3. The advantages of UOS
UOS has these 5 advantages:
(1) Super VISA transaction processing capability
UOS adopts the DPOS consensus algorithm to eliminate resource waste and solve network delay and the problems of data throughput.
The transaction processing capability of the VISA system is 10,000 times per second. UOS has the feature of high performance. The TPS of a single UOS sidechain can reach 4000, but the UOS side- chain can be expanded. Therefore, the million-level TPS can be extended as long as the sidechain is extended and surpass the level of VISA.
(2) As safe as a safe box
UOS uses the DPOS delegation to vote for the consensus algorithm, and the producter node (BP node) is elected by the coin holders, with a block generation time of 1 second. Each BP node needs to mortgage a part of the UOS tokens to an account. If the BP node is found to have misbehavior, the node’s mortgage funds will be deducted.
(3) Easy operation
UOS operation is very simple with its flexible permission system, advanced resource management mechanism, and simple address. Almost any internet programmer will be easy to start.
UOS provides DAPP developers with the underlying templates, block browsers, wallets, contract development tools. For developers with insufficient resources, UOS provides memory trading, CPU mortgage special services, and users can rent and use. If the password of the UOS account is lost, it can be retrieved. UOS transfer can be finished in seconds, which cannot be reached in other chains.
Meanwhile, UOS has no transaction fee. There is no transaction fee for trading on the UOS chain. Users can obtain the right to use the resources by mortgaging UOS tokens, thus eliminating resource abuse and hacking.
UOS makes the development of DAPP much easier. What is better than this?
(4) Strong compatibility
UOS has an independent architecture mechanism with cross-chain interaction and virtual machine. It’s like UOS’s Ethernet Virtual Machine (EVM), which supports existing Ethereum and contracts. The existing Ethereum and EOS contract can run on UOS with a slight configuration.
(5) Full autonomy.
The coin holders vote to important proposals. It is a completely autonomous system.
4. The transfer process between Ulord and UOS
The transfer process is in alliance manner, so that the decentralization can be guaranteed.
Transaction Operation Diagram
(1) Mortgage transaction
The user uses Ulord’s wallet to transfer a certain UT to the alliance address, and the alliance verifies the transaction and waits for the transaction to mature.
(2) Alliance transaction to UOS
After the mortgage transaction is verified successfully and sufficient block confirmation, the alliance releases the corresponding amount of UOS tokens to the user-specified account through the contract on UOS.
(3) Transaction redemption
The user transfers a certain amount of UOS tokens to the alliance account on the UOS chain, and the alliance verifies the transaction.
(4) Alliance’s deal with Ulord
After the redemption transaction is verified successfully and sufficient block confirmation, the alliance sends the corresponding number of UT to the Ulord address specified by the user.
5. Conclusion
The UOS sidechain is highly scalable and secure, and can support tens of thousands of DAPPs simultaneously and provide the underlying technical support template for developing DAPP.
With the development of USC, UOS and more sidechains, the TPS of the Ulord blockchain can theoretically reach a million levels of TPS to fully meet the requirements of applications.
In the development plan, Ulord designed the system as a “cluster union”. Each sidechain is like a cluster, and the bookkeeping is independent in the clusters. The value transfer is realized between the two-way peg technology, and finally a multi-cluster network structure is formed.
