briefly
Orbs is launching the Committee Sync MVP as part of the Ethereum and Arbitrum V5 upgrade to improve cross-chain transaction validation, reduce costs, and scale distributed execution infrastructure.
Orbs, a decentralized layer 3 blockchain infrastructure focused on advanced on-chain transactions, announced a major milestone with the launch of Orbs V5 with the introduction of Committee Sync MVP for Ethereum and Arbitrum. This upgrade is intended to strengthen cross-chain verification for decentralized transaction execution, while lowering infrastructure requirements and increasing participation among validators.
Orbs V5 builds on the project’s existing execution layer, supporting trading protocols such as dTWAP, dLIMIT, Liquidity Hub, Perpetual Hub, dSLTP, and Orbs Agentic. Since the launch of V4, the network reports that its infrastructure has processed over $14 billion in trading volume through the integration of over 30 decentralized exchanges across over 10 blockchain networks and generated over $3.2 million in protocol revenue.
Committee synchronization architecture improves cross-chain verification efficiency.
The updated V5 framework introduces committee synchronization, a mechanism designed to distribute authoritative layer 3 committee state across EVM-compatible chains through aggregated Guardian signatures. The system aims to reduce the operational costs and fragmentation associated with single-chain verification approaches, while mitigating the custody-related risks typically associated with bridge-based infrastructure.
“V5 is the next step in our mission, which we have been focused on for several years. V5 enables fast, reliable, and secure on-chain transactions,” Ran Hammer, Vice President of Business Development at Orbs, said in a written statement. “With new products like Orbs Agentic that expand the possibilities of automated trading in DeFi, we are improving the execution layer beneath the protocol. These changes will make execution across chains more decentralized, efficient, and scalable,” he added.
According to the Committee Sync design, Orbs executors operating off-chain transaction logic generate signed operations that are verified by the Orbs Guardian network and then propagate to the target blockchain. Smart contracts deployed on supported networks use Guardian signatures and on-chain registry rules to verify these operations locally.
Unlike bridge-based systems, the protocol does not route user funds across the network during synchronization. Instead, only signed state data is sent across the chain, eliminating reliance on centralized storage or liquidity locking mechanisms.
The initial deployment phase is already active on Ethereum and Arbitrum, with smart contracts currently synchronizing committee states, propagating nonces, and verifying signatures over a dedicated subnet infrastructure.
Future steps in the Orbs V5 roadmap include planned support for additional EVM-compatible networks: Base, Polygon, BNB Chain, Avalanche, Linea, Sonic, Berachain, and Monad. Additional planned improvements include subnet expansion, signature persistence, historical state replay functionality, and rolling out updated Guardian node software across the network.
Orbs stated that during the transition period, all existing products will continue to operate without any expected disruption to users or ecosystem partners, and the full V5 rollout is expected to take place over the coming months as additional infrastructure components are deployed.
