Péter Szilágyi	9326a118c7	beacon, core, eth, miner: integrate witnesses into production Geth (#30069 ) This PR integrates witness-enabled block production, witness-creating payload execution and stateless cross-validation into the `engine` API. The purpose of the PR is to enable the following use-cases (for API details, please see next section): - Cross validating locally created blocks: - Call `forkchoiceUpdatedWithWitness` instead of `forkchoiceUpdated` to trigger witness creation too. - Call `getPayload` as before to retrieve the new block and also the above created witness. - Call `executeStatelessPayload` against another client to cross-validate the block. - Cross validating locally processed blocks: - Call `newPayloadWithWitness` instead of `newPayload` to trigger witness creation too. - Call `executeStatelessPayload` against another client to cross-validate the block. - Block production for stateless clients (local or MEV builders): - Call `forkchoiceUpdatedWithWitness` instead of `forkchoiceUpdated` to trigger witness creation too. - Call `getPayload` as before to retrieve the new block and also the above created witness. - Propagate witnesses across the consensus libp2p network for stateless Ethereum. - Stateless validator validation: - Call `executeStatelessPayload` with the propagated witness to statelessly validate the block. Note, the various `WithWitness` methods could also just be* an additional boolean flag on the base methods, but this PR wanted to keep the methods separate until a final consensus is reached on how to integrate in production.* --- The following `engine` API types are introduced: ```go // StatelessPayloadStatusV1 is the result of a stateless payload execution. type StatelessPayloadStatusV1 struct { Status string `json:"status"` StateRoot common.Hash `json:"stateRoot"` ReceiptsRoot common.Hash `json:"receiptsRoot"` ValidationError *string `json:"validationError"` } ``` - Add `forkchoiceUpdatedWithWitnessV1,2,3` with same params and returns as `forkchoiceUpdatedV1,2,3`, but triggering a stateless witness building if block production is requested. - Extend `getPayloadV2,3` to return `executionPayloadEnvelope` with an additional `witness` field of type `bytes` iff created via `forkchoiceUpdatedWithWitnessV2,3`. - Add `newPayloadWithWitnessV1,2,3,4` with same params and returns as `newPayloadV1,2,3,4`, but triggering a stateless witness creation during payload execution to allow cross validating it. - Extend `payloadStatusV1` with a `witness` field of type `bytes` if returned by `newPayloadWithWitnessV1,2,3,4`. - Add `executeStatelessPayloadV1,2,3,4` with same base params as `newPayloadV1,2,3,4` and one more additional param (`witness`) of type `bytes`. The method returns `statelessPayloadStatusV1`, which mirrors `payloadStatusV1` but replaces `latestValidHash` with `stateRoot` and `receiptRoot`.	2 months ago

Felix Lange	e86ad52640	beacon/engine, eth/catalyst: EIP-4844 updates for the engine API (#27736 ) This is a spin-out from the EIP-4844 devnet branch, containing just the Engine API modifications and nothing else. The newPayloadV3 endpoint won't really work in this version, but we need the data structures for testing so I'd like to get this in early.
