Sei Network: What is special about Blockchain for DeFi? SEI NETWORK OVERVIEW Sei Labs, the team behind Sei Network, was founded by Jeff F., a former technology, media and telecom investment banker at Goldman Sachs, and Jayendra Jog, a former software engineer at Goldman Sachs. Robinhood. According to data from Crunchbase, Sei Labs completed a $ 5 million funding round in August of this year, right in the midst of a not so good market, with the participation of many big players such as Coinbase Ventures, Delphi. Digital, or Multicoin Capital. By the end of September, Sei had launched a $50 million ecosystem development package to attract DeFi projects to build and develop on this blockchain. WHAT IS SPECIAL WITH SEI NETWORK'S TECHNOLOGY? BLOCK PROPAGATION Previously, when the block proposer wanted to propose a block to other validators to vote and from there the whole network would have a common consensus base, they would have to go through the following steps:

1. Block proposer and validators have both seen the transactions sent to the network in their own mempool (mempool, in short, where "pending" transactions are waiting to be processed); However, the list of transactions may be slightly different because the speed at which transactions are updated to the mempool of each validator will vary depending on the network structure (topology, roughly short distance). between devices also affects the speed at which information is transmitted).

2. Next, validator A will aggregate transactions from his mempool into a complete block.

3. Then, according to the traditional operation of Tendermint, validator A will in turn send a block proposal – a message that includes the block ID (hash of a block) and the transactions in that block into individual parts. (chunks) to validator B; This means validator B has to wait for all these messages, including the block proposal and each group of transactions, to be sent to be able to reconstruct a complete block and then vote for approval, while he already has You can see these transactions in your own mempool!

4. The solution that Sei offers is that, instead of sending each part of the transaction as above, validator A will send a message including the block ID and hash functions of the transactions that need to be agreed to to validator B and then from With these hash functions, validator B can easily reconstruct a complete block.

5. In case validator B compares and finds that all transactions sent by validator A have not been received yet, B can still wait until he receives all chunks including all transactions of that block according to the traditional method mentioned above. Thanks to this new communication method, the throughput on Sei Network has been improved by 40% compared to the traditional method of Tendermint Core! BLOCK PROCESSING Steps in Tendermint consensus mechanism:

6. Propose: A proposed block for validators to vote on.

7. Prevote: validators will evaluate the validity of this block and then send a message stating their rating to the network.

8. Precommit: After a certain period of time, if more than 2/3 of the prevote messages agree with the data in the block, the validators send an approval/disagree message to the network; if there are still more than 2/3 of precommit messages expressing consensus, this block will begin to be processed and committed (ie added to the blockchain). Note: There must be 2 steps prevote and precommit although the mechanism is similar to ensure the security of the system; if there is only 1 precommit step, bad validators can still cheat successfully Parallel Transaction Processing and Order Aggregation Another improvement of Sei Network is the processing of unrelated transactions, not using the same resources separately & independently, instead of processing all transactions, even though they are related. to each other or not, sequentially. Besides, Sei Network is also designed to process transactions of different markets in parallel, saving time, thereby reducing risks for market makers (market makers). ). If the orders in a block belong to the same market, they will be aggregated to be processed at the same time. Sei Network also allows traders to aggregate multiple independent orders into a single transaction and execute them to save on gas fees. Besides helping to improve the user experience, shortening the time through this method of transaction aggregation and parallel processing also helps prevent front-running, thereby ensuring transparency. and fair to individuals participating in the market. #Crypto #Blockchain #seilors #seinami #seilorgang #IBCseilors #cosmos #DeFi #blockchain
