Sei is a Layer 1 blockchain built on the Cosmos SDK, launched on mainnet in August 2023, and designed with an explicit focus on trading applications. Its architecture incorporates several optimisations intended to improve exchange performance at the protocol level: a built-in on-chain order book module, native order matching within the consensus process, and a mechanism called Twin Turbo Consensus that combines optimistic block processing with intelligent transaction bundling to reduce latency. Sei targets decentralised exchanges, derivatives platforms, and other order-flow-intensive applications that require low confirmation times and high throughput.<\/p>\n
SEI is the native staking and governance token of the Sei network. Validators and their delegators stake SEI to participate in block production and earn staking rewards, while token holders vote on protocol parameters and upgrades. In 2024, the Sei Foundation announced a significant protocol evolution with Sei v2, which introduced EVM compatibility, allowing developers to deploy Solidity-based smart contracts alongside native Cosmos-SDK applications on the same chain. This dual-VM architecture was positioned to broaden Sei’s developer base by making the network accessible to the large pool of Ethereum-native developers without requiring them to learn a new programming environment.<\/p>\n","protected":false},"excerpt":{"rendered":"

Most Cosmos chains are general-purpose; Sei was architected from the outset to serve high-frequency financial applications where latency and throughput are the primary constraints.\"},{\"q\":\"What is Sei v2 and what does EVM compatibility mean?\",\"a\":\"Sei v2 introduced an Ethereum Virtual Machine layer alongside the existing Cosmos SDK environment, enabling developers to deploy Solidity smart contracts on Sei without modification. EVM compatibility means Ethereum-native tools, wallets, and existing contracts can function on Sei directly. The v2 upgrade was designed to expand Sei's developer community and allow it to capture liquidity from the broader Ethereum ecosystem.\"},{\"q\":\"How is the SEI token used?\",\"a\":\"SEI functions as the network's staking and gas token. Validators require delegated SEI to participate in block production, and delegators earn a share of staking rewards proportional to their stake. SEI is also used to pay transaction fees on the network and confers governance voting rights, allowing holders to influence protocol upgrades and parameter changes through on-chain proposals.\"},{\"q\":\"What risks should prospective SEI holders consider?\",\"a\":\"Sei competes with established Layer 1 networks and other Cosmos chains for developer and user attention. The trading-focused niche is narrow and dependent on decentralised exchange volumes, which are cyclical. EVM compatibility increases attack surface. SEI's staking rewards introduce token inflation. Price volatility is high, and the network's relatively recent mainnet launch means its long-term security and adoption track record is limited.\"}]"},"class_list":["post-1000207","coin","type-coin","status-publish","hentry"],"_links":{"self":[{"href":"https:\/\/themarketperiodical.com\/fr\/wp-json\/wp\/v2\/coin\/1000207","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/themarketperiodical.com\/fr\/wp-json\/wp\/v2\/coin"}],"about":[{"href":"https:\/\/themarketperiodical.com\/fr\/wp-json\/wp\/v2\/types\/coin"}],"wp:attachment":[{"href":"https:\/\/themarketperiodical.com\/fr\/wp-json\/wp\/v2\/media?parent=1000207"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
