What is Logbook
Logbook is a platform for surveys, polls, and voting — with results that can't be faked. Built on Sui blockchain.
#The Problem
When you create a poll in Google Forms, run a vote in Discord, or collect feedback through any traditional platform, you're asking participants to trust — a lot.
Trust that responses aren't manipulated. The person running the poll has full access to the data. They can edit responses, delete inconvenient votes, or hide results entirely. You'd never know.
Trust that results are accurate. The platform shows you a number. Maybe it's correct, maybe it isn't. You can't access the raw data to count yourself. You just have to believe what you're shown.
Trust that records will exist tomorrow. Platforms shut down. Accounts get deleted. Polls expire. Six months from now, there may be no evidence the vote ever happened — no way to reference what was decided or prove the outcome.
This isn't a hypothetical problem. It's the default. Every traditional voting tool works this way: truth is whatever the platform — or the organizer — decides to show you.
#The Solution
Logbook takes a different approach: instead of asking you to trust, it gives you the ability to verify.
Every response is recorded on the Sui blockchain — a public, decentralized ledger that no single party controls. This changes everything:
Immutable records. Once a response is submitted, it's written to the blockchain permanently. No one can edit it, delete it, or pretend it never happened — not the organizer, not the platform, not even us.
Public verification. Every response has a transaction hash. Anyone can look it up on a Sui block explorer such as Suiscan and verify it exists. You don't have to trust the results we show you — you can check them yourself.
Permanent storage. Blockchain data doesn't expire when a subscription lapses or a company shuts down. As long as the Sui network exists, your records exist. Reference them years later as proof of what was decided.
No central authority. There's no admin who can quietly change the rules mid-vote. The rules live in a smart contract — code that executes exactly as written, every time. Once the first response arrives, the questions can no longer be changed or deleted.
Private when it needs to be. Not every vote should be public. Campaigns can be limited to people with a password or to a list of addresses, and answers can be readable by everyone, only by voters, only by you, or by nobody until the vote ends. Private data is encrypted in the browser, and the smart contract decides who gets the decryption keys — not Logbook.
The result: a voting tool where trust is optional. Everything that matters is verifiable.
#Use Cases
- Community voting: Transparent governance decisions
- Research surveys: Collect feedback with provable authenticity
- Event registration: Immutable attendance records
- Polls and opinions: Public sentiment with verifiable results
- Secret ballots: Answers stay sealed until the vote ends
- Confidential feedback: Only the organizer can read the answers
- Certification: Issue verifiable credentials and test results
#Works With AI Agents
Everything above can be done by an AI agent on your behalf: through a connector in claude.ai or another chat, through a local MCP server, or simply through a link the agent prepares and you approve in the browser. See API & SDK for the three ways and how they differ.
