Products Overview

An Information Sheet NFT lets you write a combination of information directly to the Ethereum blockchain. You own the resulting NFT in your wallet — it belongs to you, permanently and verifiably.

What you can include:

• Messages — any text you want preserved on the blockchain
• Binary data — raw bytes for technical use cases
• SHA256 / SHA512 hashes — digital fingerprints of your files (what is hashing?)
• ProofSets — hash multiple files into a single verifiable record (what are ProofSets?)

Requirements:

Blockchain Proof writes a SHA256 hash to the Ethereum blockchain using a credit card, Apple Pay, Google Pay, or other payment methods supported by Stripe. No crypto wallet needed — this product is designed for anyone who wants blockchain-backed proof without managing a wallet.

Create a hash from:

• A file or files — select documents, images, or any files
• Text you enter — type or paste any text to hash
• A hash you already have — paste a SHA256 you created elsewhere

What you get:

• An email receipt from the payment processor with transaction details
• An email receipt from AlwaysProof with your proof details (multi-party corroboration)
• A sharing certificate you can use to share or present your proof

Note: Blockchain Proof does not create an ownable NFT. It writes your hash to the blockchain and provides receipts confirming the transaction.
