Polkadot ecosystem DeFi network Acala stated that after seven years of development, Acala and its sister network Karura located in Kusama are entering the final phase. Under the premise that Acala's referendum No. 195 and Karura's referendum No. 137 are passed, both networks will cease operations on February 10, 2027. After this date, Acala and Karura will no longer produce new blocks.Users need to withdraw DOT, KSM, and assets bridged from other chains, such as USDT and USDC, from Acala and Karura before February 10, 2027. LDOT unbonding requires 28 days and must be initiated before January 12, 2027; if LDOT is locked with a validator, an additional 28 days is needed for unlocking, which must be completed before December 16, 2026. LKSM unbonding requires 7 days and must be initiated before February 2, 2027.ACA and KAR are the native tokens of the two networks and cannot be withdrawn; they will remain on their respective chains. For external assets that have not been withdrawn before the deadline, the team will return them as much as possible; as a last resort, recoverable assets can be returned to the same account's address on the Polkadot or Kusama Asset Hub, but not all assets can be returned in this way. Acala was founded by Bryan, Ruitao, and Bette, who initially developed the synthetic assets and margin trading project Laminar, and later, at the invitation of the Web3 Foundation, built the Polkadot ecosystem stablecoin, evolving into Acala.

The blockchain infrastructure company Gattaca announced the launch of the open-source Ethereum consensus client Silver. The company operates the Ethereum block builder Titan Builder and the relay Titan Relay. Gattaca stated that Silver was built from scratch, aiming to support shorter time slots and post-quantum security while maintaining decentralization, censorship resistance, privacy, and security. Currently, Silver is in the alpha stage, with audits and final testing yet to be completed.Gattaca claims that Silver's state transition function has a p99 latency of less than 10 milliseconds, approximately 10 times faster than other clients. During the mainnet window from October 17 to 20, 2026, Silver, Prysm, Lighthouse, and Grandine processed the same 20,300 canonical blocks. The median block processing latency for Silver was 6.5 milliseconds, with a p99 of 9.5 milliseconds, and the slowest block in the sample was 17.8 milliseconds; the second-lowest median was 33.5 milliseconds, and the second-lowest p99 was 91 milliseconds. All four clients operated as supernodes, subscribing to all 64 proof subnets and hosting all 128 data columns, with the executing client being ethrex v29.0.1.The above comparison used consensus processing metrics available for each client, excluding execution client processing time. Silver is based on Gattaca's Flux framework, using six threads bound to CPU cores for parallel processing, and comes with a low-latency peer-to-peer network, state hash library, formally verified BLS and KZG cryptographic libraries, and a node cluster for penalty protection. In another comparison, supernodes needed to verify about 32 times the proofs and about 16 times the KZG unit proofs relative to the default configuration, with block processing latency and resident memory still within a similar range.
