Espresso officially announced that its Decaf testnet has achieved subsecond finality. The testnet uses the same node geographic distribution as the mainnet, with the current confirmation time at approximately 0.24 seconds. The team is working to further narrow the performance gap with the mainnet. The next phase will push this performance target toward mainnet deployment. Previously, the project was positioned as shared sequencing and rapid finality infrastructure for Rollups, aiming to enhance transaction confirmation speed and interoperability in the multi-chain ecosystem. https://(wublock123.com)/news/espresso-testnet-subsecond-finality-mainnet-deployment-ready-66963
