Hive Smart Contracts Build Status

1. What is it?

Hive Smart Contracts is a sidechain powered by Hive, it allows you to perform actions on a decentralized database via the power of Smart Contracts.

2. How does it work?

This is actually pretty easy, you basically need a Hive account and that's it. To interact with the Smart Contracts you simply post a message on the Hive blockchain (formatted in a specific way), the message will then be catched by the sidechain and processed.

3. Sidechain specifications

  • run on node.js
  • database layer powered by MongoDB
  • Smart Contracts developed in Javascript
  • Smart Contracts run in a sandboxed Javascript Virtual Machine called VM2
  • a block on the sidechain is produced only if transactions are being parsed in a Hive block

4. Setup a Hive Smart Contracts node

see wiki:

In addition, the following is needed to use transaction framework for MongoDB:

Also, if using PM2, you will need to start the process with --no-treekill for proper shutdown. Also consider using --no-autorestart with proper monitoring to minimize noise and potential for problematic looping (though with transactions there is less risk of data corruption). Another oddity with PM2 is that you may need to clear node processes after a stop if the process does not terminate on its own. Otherwise it will interfere with logging.


pm2 start app.js --no-treekill --kill-timeout 10000 --no-autorestart

DB Backup and Restore

Backup current state (track current hive blpck in config)

mongodump -d=hsc --gzip --archive=hsc_50287280.archive

Restore state

mongorestore --gzip --archive=hsc_50287280.archive

Edit config.json to match block number of backup.

5. Tests

  • npm run test
