## Key points

- Orbs V5 的 Committee Sync MVP 現已在以太坊與 Arbitrum 上線，實現跨鏈委員會狀態傳播。
- Committee Sync 消除了每條鏈驗證的需求，降低成本並減少驗證者分散。
- 該機制利用 Guardian 簽名同步 EVM 鏈上的交易執行數據，且不涉及用戶資金託管。
- 未來階段將擴展 Committee Sync 至 Base、Polygon、BNB Chain、Avalanche、Linea、Sonic、Berachain 及 Monad。
- 所有 Orbs 產品在 V5 遷移期間將正常運作，預期不會對用戶造成中斷。

Orbs, a decentralized Layer 3 blockchain infrastructure focused on advanced on-chain trading, has announced a major milestone in the development of Orbs V5 with the launch of its Committee Sync MVP on Ethereum and Arbitrum. The upgrade is designed to improve how decentralized trading execution is verified across chains while reducing infrastructure overhead and expanding validator participation. Since the release of V4, Orbs says its infrastructure has processed more than $14 billion in trading volume across more than 30 DEX integrations on over 10 blockchain networks, generating more than $3.2 million in protocol revenue. The network powers trading protocols, including dTWAP, dLIMIT, Liquidity Hub, Perpetual Hub, dSLTP, and Orbs Agentic. How Committee Sync works The new V5 architecture introduces Committee Sync, a mechanism that propagates authoritative Layer-3 committee state across EVM-compatible chains using collected Guardian signatures. The approach reduces the costs and fragmentation associated with per-chain verification systems while avoiding the custody risks associated with bridges. No user funds pass through the protocol during synchronization; only signed state data is propagated across chains, removing the need for centralized custody or liquidity lockups. The mechanism allows Orbs executors running trading logic off-chain to generate signed actions that are verified by the Orbs Guardian network and propagated to destination chains. Smart contracts on supported networks can then verify those actions locally using Guardian signatures and registry rules enforced on-chain. “V5 is the next step in our mission, which we have focused on for years. It allows fast, reliable, and secure on-chain trading,” said Ran Hammer, VP of Business Development at Orbs. “With new products like Orbs Agentic expanding what’s possible for automated trading in DeFi, we’re improving the execution layer beneath our protocols. This change will make execution more decentralized, efficient, and scalable across chains.” Rollout timeline The first phase of the rollout is already operational on Ethereum and Arbitrum, with deployed smart contracts actively synchronizing committee state, propagating nonces, and verifying signatures on-chain through a dedicated subnet infrastructure. Future phases include expanded support for Base, Polygon, BNB Chain, Avalanche, Linea, Sonic, Berachain, and Monad, alongside subnet expansion, signature persistence, historical state replay functionality, and deployment of new Guardian node software. Orbs said all existing products will remain operational throughout the migration, with no expected disruption for users or ecosystem partners. The broader V5 rollout is expected to continue over the coming months.
