### EIP-4844 Shard Blob Transactions Support (experimental)
This library supports an experimental version of the blob transaction type introduced with [EIP-4844](https://eips.ethereum.org/EIPS/eip-4844) as being specified in the [01d3209](https://github.com/ethereum/EIPs/commit/01d320998d1d53d95f347b5f43feaf606f230703) EIP version from February 8, 2023 and deployed along `eip4844-devnet-4` (January 2023) starting with `v1.3.0`.
#### Initialization
To run EVM related EIP-4844 functionality you have to active the EIP in the associated `@ethereumjs/common` library:
```typescript
import { Common, Chain, Hardfork } from '@ethereumjs/common'
const common = new Common({ chain: Chain.Mainnet, hardfork: Hardfork.Shanghai, eips: [4844] })
```
EIP-4844 comes with a new opcode `DATAHASH` and adds a new point evaluation precompile at address `0x14`.
**Note:** Usage of the point evaluation precompile needs a manual KZG library installation and global initialization, see [KZG Setup](https://github.com/ethereumjs/ethereumjs-monorepo/tree/master/packages/tx/README.md#kzg-setup) for instructions.
