/eth/v1/validator/blinded_blocks/{slot}

Produce a new blinded block, without signature

Produce a new blinded block, without signature.

get

Requests a beacon node to produce a valid blinded block, which can then be signed by a validator. A blinded block is a block with only a transactions root, rather than a full transactions list.

Metadata in the response indicates the type of block produced, and the supported types of block will be added to as forks progress.

Pre-Bellatrix, this endpoint will return a BeaconBlock.

Path parameters
slotstringRequired

The slot for which the block should be proposed.

Example: 1
Query parameters
