What is send_blob?

[mirmohmmadluqman]

send_blob refers to a code example or script that demonstrates how to send a "blob transaction" on the Ethereum blockchain. This is tied to EIP-4844 (also known as proto-danksharding), a major upgrade introduced in Ethereum's Dencun hard fork in March 2024. Blobs are essentially large chunks of binary data (up to 128 KB each, with a transaction supporting up to 6 blobs) designed to make Layer 2 rollups (like Optimism or Arbitrum) cheaper and more efficient. Unlike regular transaction data (calldata), blobs aren't permanently stored on-chain after a short availability window (a few weeks), which keeps costs low while ensuring data is verifiable for security.

In simple terms:

• Why blobs? Ethereum was getting expensive for L2s to post transaction batches (data availability). Blobs offload this by providing "temporary" storage that's only needed briefly for validation, slashing fees by 10-100x for rollup users.
• How it works: A blob transaction (type 3) includes commitments (via KZG polynomials) to the blob data, which is gossiped separately via the consensus layer. The EVM can't directly access blobs—it's for data availability, not execution.
• send_blob code: This is typically a tutorial script (in Python with web3.py or JS with ethers.js/viem) that builds, signs, and broadcasts such a transaction. It pads data to fit blob requirements (e.g., 4096 field elements of 32 bytes) and handles fees like blob gas.

The most straightforward GitHub repo for this is: https://github.com/PatrickAlphaC/send_blob

It includes a simple Python example using web3.py to send a blob tx on a local Anvil node. Clone it, set up with rye sync, and run rye run send-blob after configuring your RPC and private key. For more advanced tools, check https://github.com/ethstorage/eth-blob-uploader (CLI for uploading files as blobs).

I see, Interesting.

After checking reliable sources, the most direct match is a GitHub repository demonstrating how to send a blob on the blockchain.

Here's the GitHub link: https://github.com/PatrickAlphaC/send_blob

This repo includes code examples (primarily in JavaScript/TypeScript with Hardhat for Ethereum) to deploy a contract and send blob data. If this isn't the exact one you meant, it could be related to general blob handling in web apps—let me know for further refinement, but this seems spot-on.
