About blocksign.red

Blocksign.red is a blockchain-anchored electronic signature platform. You upload a document, sign it, and we seal the cryptographic proof to two public blockchains. The result is a tamper-evident audit trail that no single company — including us — can alter or suppress. It works for humans in a browser and for AI agents over an API.

Mission

Make every agreement independently verifiable, permanently anchored, and accessible to any signer — human or machine.

How it works

  1. 1

    Upload

    Drop a PDF, paste text, or send Markdown. Our AI detects signature fields and places them automatically.

  2. 2

    Sign

    You and your counterparties sign electronically. Each signature generates a cryptographic hash of the complete document state.

  3. 3

    Anchor

    The hash is submitted to XRPL (confirmed in 2-3 seconds) and to Bitcoin via OpenTimestamps (confirmed in the next block, preserved forever).

  4. 4

    Verify

    Anyone with the document can independently verify its integrity against both chains. No account required. No trust required.

Why two chains?

XRPL gives us speed. Transactions finalize in 2-3 seconds with negligible cost, so signers get real-time confirmation. Bitcoin gives us permanence. Its proof-of-work chain is the most attack-resistant ledger in existence. Together they provide immediate assurance and long-term durability — complementary guarantees from independent networks.

AI-first philosophy

Blocksign.red ships with a Model Context Protocol (MCP) server. Any AI agent that speaks MCP can create agreements, upload documents, place fields, send for signature, and retrieve anchored proofs — all in a single call. Issue scoped agent keys with granular permissions. Automate contract workflows without building custom integrations.

Blocksign.red is a product of Boneyard Software LLC — building infrastructure for the next generation of agreements, where software signs as often as people do and every commitment is backed by public, immutable proof.
