On Wednesday, the Sei team announced via X that the Eidos upgrade is now live on the Sei network. Eidos is the storage track of the Giga upgrade. It will completely rebuild how Sei stores state and history while the chain keeps producing blocks.
Eidos retires the Merkle tree for Sei’s EVM state. Its replacement, a store called FlatKV, keeps state in a flat key-value layout where one change is one write. A lattice hash (LtHash) maintains a running fingerprint of the entire state that updates in constant time per change, without cascading recomputation. The network keeps its ability to verify everything.
Data moves across in small batches, block by block, with the old and new stores running side by side until the new one has proven itself, and the whole rollout is switched on by governance and reversible by design. It’s also checked at every step: shadow nodes replayed real mainnet traffic against the new stores before rollout, integrity hashes are audited continuously, and in testing, block times stayed essentially unchanged while the migration ran underneath.
Sei is a blockchain designed for fast, cheap financial transactions, combining the network effects of Ethereum with the performance of Solana. Sei has processed more than five billion transactions across more than 90 million wallets and has become the #1 EVM chain by number of active users. The team is backed by top investors such as Multicoin, Jump, Coinbase Ventures, and Circle Ventures – and includes talent from companies like Robinhood, Google, Coinbase, Databricks, Uber, and Goldman Sachs.
Sei is a high-speed Layer 1 blockchain tailored for the digital asset boom, from NFTs to DeFi. The blockchain intends to unlock a brand-new design space for consumer-facing applications.
Sei's security is anchored in a multifaceted approach that integrates advanced technology, stringent security protocols, and a commitment to transparent governance. At its core, Sei leverages a sector-specific Layer 1 blockchain architecture, designed specifically for trading, which inherently enhances its security profile by catering to the unique demands of decentralized exchanges (DEXes). This specialization allows Sei to offer unparalleled transaction speeds and reliability, crucial for DEX operations where even brief downtimes can have significant repercussions.
Its native coin, SEI is up 4.1% in the last 24 hours and is now trading at $0.04169 per coin.
