About B3Note
## Overview
B3Note is a decentralized platform built on the Internet Computer that allows you to create and share notes. With strong encryption and blockchain-based verification, B3Note emphasizes privacy and security. The platform offers two distinct features: anonymous note sharing and authenticated note sharing.
## Key Features
– **Anonymous Usage**: B3Note can be used anonymously, with no login required.
– **Limited Notes for Anonymous Users**: Create up to 5 notes, each with a 1-hour timeout. After this period, the notes are automatically deleted. Additionally, any generated share link will also expire after 1 hour.
– **Canister Global Timer**: A global timer is employed to clean up expired users and one-time keys, thereby enhancing system efficiency and security.
– **Secure Sharing with On-Chain Verification**: Notes can be securely shared through a simple link that carries the signature of your public key. This signature is verifiable on-chain and pairs with the note’s unique ID to confirm access to the decryption key for that note.
– **Auto Deletion**: Notes are automatically deleted either after they have been read for the first time or if they remain unread for an hour.
– **Advanced Encryption**: B3Note uses a form of witness-like encryption to ensure that only authorized users with the correct credentials can access the notes.
– **Timelock Encryption**: Encrypted decryption keys, notes, and shared links come with a built-in expiry feature, aligning with the concept of Timelock Encryption for temporary secure access.
