Sei

Banner!

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 the entire Cosmos ecosystem, including IBC tokens, multi-sig accounts, fee grants, and more.

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.

Seid Installation Steps

Clone git repository

git clone https://github.com/sei-protocol/sei-chain
cd sei-chain
git checkout $VERSION
make install

Generate keys

  • seid keys add [key_name]

  • seid keys add [key_name] --recover to regenerate keys with your mnemonic

  • seid keys add [key_name] --ledger to generate keys with ledger device

Validator setup instructions

  • Install seid binary

  • Initialize node: seid init <moniker> --chain-id sei-testnet-1

  • 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.

[Unit]
Description=Sei-Network Node
After=network.target

[Service]
Type=simple
User=root
WorkingDirectory=/root/
ExecStart=/root/go/bin/seid start
Restart=on-failure
StartLimitInterval=0
RestartSec=3
LimitNOFILE=65535
LimitMEMLOCK=209715200

[Install]
WantedBy=multi-user.target

Start the node

Start seid on Linux

  • Reload the service files: sudo systemctl daemon-reload
  • Create the symlinlk: sudo systemctl enable seid.service
  • Start the node sudo: systemctl start seid && journalctl -u seid -f

Start a chain on 4 node docker cluster

  • Start local 4 node cluster: make docker-cluster-start
  • SSH into a docker container: docker exec -it [container_name] /bin/bash
  • Stop local 4 node cluster: make docker-cluster-stop

Create Validator Transaction

seid tx staking create-validator \
--from {{KEY_NAME}} \
--chain-id  \
--moniker="<VALIDATOR_NAME>" \
--commission-max-change-rate=0.01 \
--commission-max-rate=1.0 \
