Blocknote

Blocknote is an open, lightweight protocol for storing data directly on the Algorand blockchain. It lets developers and users publish permanent, decentralized content on-chain using nothing more than Algorand Layer 1 transactions.

• 🖼️ Store files on-chain + update them keeping the versioning

• 📡 Stream continuous data feeds, ideal for IoT devices, sensors and real-time logs

• 🔒 Protect content using password or AES encryption

• 💸 Optimize costs with a smart compression

Blocknote uses a simple, extensible model based on a payload transaction that contains metadata about the content (such as type, compression, and encryption).

Whether you're building an archival tool, a decentralized publishing platform, or a creative inscription project, Blocknote gives you the freedom to write to the chain simply and efficiently.
