Sei
Sei is the fastest general purpose L1 blockchain and the first parallelized EVM. This allows Sei to get the best of Solana and Ethereum - a hyper optimized execution layer that benefits from the tooling and mindshare around the EVM.
Overview
Sei is a high-performance, low-fee, delegated proof-of-stake blockchain designed for developers. It supports optimistic parallel execution of both EVM and CosmWasm, opening up new design possibilities. With unique optimizations like twin turbo consensus and SeiDB, Sei ensures consistent 400ms block times and a transaction throughput that’s orders of magnitude higher than Ethereum. This means faster, more cost-effective operations. Plus, Sei’s seamless interoperability between EVM and CosmWasm gives developers native access to multi-sig accounts and more.

Starting with v6.7, IBC module source and wiring are removed. IBC queries, historical transfer transaction decoding, and pre-v6.7 IBC precompile tracing are not served by v6.7 nodes. Run a v6.6 freeze node to serve pre-v6.7 IBC history. The IBC precompile at 0x1009 remains registered only as a tombstone that reverts every call. Starting with v6.8, the ibc, transfer and capability stores are deleted from state, and the four passed ClientUpdateProposal records (proposals 52, 81, 100 and 119) are rewritten as TextProposals keeping their title and description; v6.8 nodes cannot answer gov state queries at pre-v6.8 heights for those records, use a v6.6 freeze node. CosmWasm IBC entry points, messages and queries are still compiled into sei-wasmd but have no IBC module behind them; they go away with the CosmWasm teardown.
Sei Optimizations
Sei introduces four major innovations:
- Twin Turbo Consensus: This feature allows Sei to reach the fastest time to finality of any blockchain at 400ms, unlocking web2 like experiences for applications.
- Optimistic Parallelization: This feature allows developers to unlock parallel processing for their Ethereum applications, with no additional work.
- SeiDB: This major upgrade allows Sei to handle the much higher rate of data storage, reads and writes which become extremely important for a high performance blockchain.
- Interoperable EVM: This allows existing developers in the Ethereum ecosystem to deploy their applications, tooling and infrastructure to Sei with no changes, while benefiting from the 100x performance improvements offered by Sei.
All these features combine to unlock a brand new, scalable design space for the Ethereum Ecosystem.

Generate keys
Validator setup instructions
-
Install seid binary
-
Initialize node (use --mode validator so RPC/P2P bind to localhost): seid init <moniker> --chain-id sei-testnet-1 --mode validator
-
Download the Genesis file: wget https://github.com/sei-protocol/testnet/raw/main/sei-testnet-1/genesis.json -P $HOME/.sei/config/
-
Edit the minimum-gas-prices in ${HOME}/.sei/config/app.toml: sed -i 's/minimum-gas-prices = ""/minimum-gas-prices = "0.01usei"/g' $HOME/.sei/config/app.toml
-
Start seid by creating a systemd service to run the node in the background
nano /etc/systemd/system/seid.service
Copy and paste the following text into your service file. Be sure to edit as you see fit.
