v1.10-alpha6
Overview
This alpha release adds support for the upcoming Fusaka upgrade on the Holesky, Sepolia, and Hoodi testnets.
For details about when the testnets will be upgraded, refer to the Ethereum Foundation's fusaka testnet annoucement.
Docker Image: flashbots/mev-boost:1.10a6
Changes since v1.10-alpha5
From the v1.10-alpha5 release, this release adds support to fallback to eth/v1/builder/blinded_blocks api if eth/v2/builder/blinded_blocks api fails.
ethereum/builder-specs#123 introduces the eth/v2/builder/blinded_blocks API which doesn't return the fully signed block back to the proposer to save network bandwidth and relys on the mev-boost-relay to publish the block to the network.
If by any chance, the v2 API is not implemented by a relay provider it can cause a missed slot. To avoid such situations, we fallback to the v1 API in case the v2 API has not been implemented.
