Sigil.bot
A zero-install, message-native provenance layer.
DM the bot with the content you want to anchor. You receive a signed receipt: a hash of the content, a timestamp, and a CC-BY attribution license, signed by Sigil. The receipt is committed to the blockchain. Anyone can verify it against the chain without contacting Sigil's servers.
How it works
- You DM the bot with the content you want to anchor.
- You receive a signed receipt: a hash of the content, a timestamp, and a CC-BY attribution license, signed by Sigil.
- The receipt is committed to the blockchain.
- Anyone can verify the receipt against the chain. No Sigil server required.
Why it matters
Ideas travel through chats before they reach a platform. By the time a thought becomes an article, a product, or a policy, the person who first said it has often disappeared from the record. This happens to everyone, and most of all to voices routinely taken without recognition: unhoused contributors, grassroots storytellers, people whose lived experience shapes policy, research, and reporting they are rarely cited in. Sigil is a small fix that survives the operator.
