Gives the beacon node instructions on how to build and publish a SignedBeaconBlock by substituting the whole list of transactions for the transactions_root. This is done by using the components of the SignedBlindedBeaconBlock. To be added to the beacon chain, the beacon node needs to broadcast a freshly created SignedBeaconBlock to the beacon network. A successful response (20X) just signifies that the broadcast was successful; the beacon node is not needed to verify the signed BeaconBlock. The beacon node is supposed to incorporate the new block into its state and validate it internally. Blocks that don't pass this internal validation process are nevertheless broadcast, but they receive a different status code (202). This endpoint will accept a SignedBeaconBlock before Bellatrix.
In this section, we provide an illustrative example of a request made to retrieve details contents using the /v1/beacon/blinded_blocks
endpoint. Additionally, we present the resulting response containing information about publishing a signed block.
200: OK Expand for a detailed response example
Copy The block was validated successfully and has been broadcast. It has also been integrated into the beacon node's database.
