Network Highlight: bolt by Chainbound
bolt by Chainbound is live on Symbiotic mainnet, introducing credible proposer commitments to Ethereum. Through bolt's unique validator-centric design, validators can make verifiable commitments to include specific transactions in their blocks, backed by the economic security of Symbiotic's vault system. These commitments open the door to new use cases on Ethereum, starting with sub-second preconfirmations.
A Fresh Take on Validator-Level Security
bolt stands out through its approach to validator-centric security. Unlike systems that operate through relays and builders, bolt creates direct economic relationships between individual validators and their commitments. This precise mapping means validators capture value directly through increased priority fees, while using Symbiotic's slashing mechanisms to enforce their promises.
By aligning with Ethereum's native validator rotation and lookahead window, bolt achieves remarkable capital efficiency. Validators only need to maintain active collateral during their specific proposal windows plus a short challenge period. This design lets operators cycle the same collateral across multiple validators, significantly reducing capital requirements while maintaining robust security guarantees.
Augmenting Ethereum's Infrastructure
bolt demonstrates how Symbiotic's modular security can enhance existing blockchain networks. By adding cryptoeconomic guarantees to Ethereum's proposer-builder separation (PBS), bolt strengthens the reliability of block inclusion and MEV distribution. This implementation shows how shared security can complement rather than replace native consensus mechanisms.
The deployment pushes the boundaries of validator economics on Ethereum. By making block commitments both credible and enforceable, bolt opens up new design spaces for protocols requiring stronger transaction guarantees. The combination of Ethereum's consensus with Symbiotic's economic security creates possibilities that neither system could enable alone.
A New Chapter in Shared Security
bolt's implementation highlights the adaptability of Symbiotic's security framework. Their approach to validator collateral management and commitment enforcement demonstrates how networks can leverage Symbiotic's primitives to create precisely tailored security models.
bolt’s Genesis launch is now accepting node operator registrations. Validators can connect via bolt's registry using Symbiotic’s operator system. Join an existing or launch a new bolt-enabled vault to participate in this evolution of Ethereum's proposer ecosystem.
