blobsToProofs

Compute the proofs for a list of blobs and their commitments.

Import

import { blobsToProofs } from 'viem'

Usage

example.ts
import { blobsToCommitments, blobsToProofs, toBlobs } from 'viem'
import { kzg } from './kzg'
 
const blobs = toBlobs({ data: '0x...' })
const commitments = blobsToCommitments({ blobs, kzg })
const proofs = blobsToProofs({ blobs, commitments, kzg })

Returns

Hex[] | ByteArray[]

Proofs from the input blobs and commitments.

Parameters

blobs

  • Type: Hex[] | ByteArray[]

Blobs to transform into proofs.

import { blobsToCommitments, blobsToProofs, toBlobs } from 'viem'
import { kzg } from './kzg'
 
const blobs = toBlobs({ data: '0x...' }) 
const commitments = blobsToCommitments({ blobs, kzg })
 
const proofs = blobsToProofs({ 
  blobs, 
  commitments, 
  kzg 
})

commitments

  • Type: Hex[] | ByteArray[]

Commitments corresponding to the input blobs.

import { blobsToCommitments, blobsToProofs, toBlobs } from 'viem'
import { kzg } from './kzg'
 
const blobs = toBlobs({ data: '0x...' })
const commitments = blobsToCommitments({ blobs, kzg }) 
 
const proofs = blobsToProofs({ 
  blobs,
  commitments,  
  kzg 
})

kzg

  • Type: KZG

KZG implementation. See setupKzg for more information.

import * as kzg from 'c-kzg'
import { blobsToProofs, setupKzg } from 'viem'
import { mainnetTrustedSetupPath } from 'viem/node'
 
const blobs = toBlobs({ data: '0x...' })
const commitments = blobsToCommitments({ blobs, kzg })
const kzg = setupKzg(cKzg, mainnetTrustedSetupPath) 
 
const proofs = blobsToProofs({ 
  blobs,
  commitments,
  kzg, 
})
