NEAR Paste

NEAR Paste is an open-source blockchain-based Pastebin built on NEAR Protocol. The server has zero knowledge about any pasted data. Data is encrypted/decrypted using AES encryption in the browser itself.

The application neither requires user to login/signup nor connecting to any wallet. All pastes are funded by app's account itself.

Testnet account: nearpaste.testnet

Features

• Paste encryption with Password: Encryption/decryption of data takes place in-browser. Your password is NEVER sent to server.
• Zero-knowledge access: Server has no knowledge about any paste data being sent to blockchain.
  • Note: The server does not log any paste data. However, paste data content is visible in NEAR explorer. It is suggested to use password.
