PostBeaconBlindedBlocksV2

Publish a signed block.

Instructs the beacon node to use the components of the SignedBlindedBeaconBlock to construct and publish a SignedBeaconBlock by swapping out the transactions_root for the corresponding full list of transactions. The beacon node should broadcast a newly constructed SignedBeaconBlock to the beacon network, to be included in the beacon chain. The beacon node is not required to validate the signed BeaconBlock, and a successful response (20X) only indicates that the broadcast has been successful. The beacon node is expected to integrate the new block into its state, and therefore validate the block internally, however blocks which fail the validation are still broadcast but a different status code is returned (202). Before Bellatrix, this endpoint will accept a SignedBeaconBlock. The broadcast behaviour may be adjusted via the broadcast_validation query parameter.

Path parameters

apiKeystring required

Query parameters

broadcast_validation'gossip' | 'consensus' | 'consensus_and_equivocation'

Level of validation that must be applied to a block before it is broadcast.

Possible values:

gossip (default): lightweight gossip checks only
consensus: full consensus checks, including validation of all signatures and blocks fields except for the execution payload transactions.
consensus_and_equivocation: the same as consensus, with an extra equivocation check immediately before the block is broadcast. If the block is found to be an equivocation it fails validation.

If the block fails the requested level of a validation a 400 status MUST be returned immediately and the block MUST NOT be broadcast to the network.

If validation succeeds, the block must still be fully verified before it is incorporated into the state and a 20x status is returned to the caller.

Headers

Eth-Consensus-Version'phase0' | 'altair' | 'bellatrix' | 'capella' | 'deneb' required

Example:phase0

Version of the block being submitted.

Response

The block was validated successfully and has been broadcast. It has also been integrated into the beacon node's database.
