• Explorer: Test-net https://sei.explorers.guru/; https://testnet-explorer.brocha.in/sei/ -

• Product: Sei Network is the first orderbook-specific L1 blockchain, custom-built for DeFi applications. Features a built-in order-matching engine, frontrunning protection, and the fastest finality of any chain (600 ms).

• Language: Go

• Protocol Consensus: Tendermint +

• Stats: Twitter: 33K, Discord: 4.6k , Telegram: 4.3k; Since launch in July → 58 Active Validators (2000 Test-net validators); 25k Test-net users

• Investors: $5 million funding round led by Multicoin Capital with participation from Coinbase Ventures, Delphi Digital, Hudson River Trading, GSR, Hypersphere, Flow Traders, Kronos Research and the founders of Anchorage, Frax, Yield Guild Games, and Tangent.

• Competitors: Maverick Protocol, Injective, Serum, DyDx

• Roadmap: Main-net Q1 2023 target

• Pros:
1. DeFi specific environment build on Cosmos SDK
2. Cross-chain integration (IBC and Solana trough Nitro L2)
3. plug-and-play into the Sei order matching engine and access pooled liquidity from other apps.

• Cons:
• The first mover, Injective, has great traction and stat, this could lead to a high barrier to entry into the IBC ecosystem
• No Tokenomics info out yet.
• Not clear on which ecosystem they want to relay (switching btw Cosmos, Solana etc) why airdrop to Solana users?

• Collab announced - @Nitro_Labs will deploy its scaling solution on Sei serving as a portal for the #Cosmos and #Solana communities.
Nitro lets developers deploy existing Solana smart contracts with no changes, while users can seamlessly access these apps with Solana wallets.
Incubated by contributors at Sei Labs, Nitro provides a platform for Solana developers looking to expand to the IBC markets.

• 50 Million Ecosystem and liquidity fund to support new decentralized finance (DeFi) applications on its platform.

• Latency & Throughput
• Overloading Tendermint: Sei the fastest chain to finality (600ms)
• DeFi-specific parallelization: massively increases throughput and order processing
• Optimistic block processing: heavily decreases block latency

• Mev Protection
Frequent batch auctioning: rather than executing each order one-by-one (as would happen on Ethereum or Solana). Sei can aggregate every order together at the end of the block and execute all market orders at the same price to help prevent frontrunning

• Developer and User Experience
Native price oracles: built into the chain itself for high quality and reliable data feeds
Single block order execution: on Serum, apps need 1 transaction to place an order (adding it to a queue) and then another transaction (in another block) to “turn the crank” for order execution. Sei collapses that into 1 block for faster order execution.
Multiple levels of order bundling: to minimize gas costs so market makers and pro traders on apps built on Sei can submit 1 transaction to update multiple markets
Multi-Token Gas: gas can get paid with multiple token options

1. Native Order Matching

2. Twin-Turbo Consensus

3. Market-based parallelization
Order matching is the heaviest L1-level operation on Sei. Since performance is of paramount importance for an exchange, we implemented parallel order matching to speed up the process. Different trading pairs will have their order-matching process running in parallel in DEX module's EndBlock section.

This is inefficient - Validators due to network latency have to wait for data that they already have

• Optimal Solution: Hashes of Txn from TXN A→E are included in the block proposal, so the validator can construct the block locally (with the mempool data)

• 0.01% Case: The Validator will Fallback to the same mechanism previously used (as Normal tendermint)

This is inefficient - Validators are waiting for the entire length of prevote and pre-commit without starting to process the block.

• Optimal Solution: Optimistic Processing→ While the prevote and pre-commit are happening, at the same time the Validator is processing the block →Block is processed faster and the state updates are faster. Overall latency goes down.

• In case of a malicious node or a validator makes a mistake: Validators are taking the proposal, updating a candidate state, if the proposal is successful they will commit that state, if not the state will be discarded. Next round, at any given height, the block will be processed the normal way as after pre-commit.
