On February 28, 2018, IOTA has announced that the new and improved IOTA PoWbox, which was previously IOTA Sandbox, was released and is ready for use. PoWbox is useful first of all for developers, as it allows Proof of Work to be done not on the developer’s local machine but on a separate remote server farm which does the computation in a fraction of the time.
As it was stated in the official announcement of IOTA, PoWbox has some major improvements, but works similarly to the old Sandbox:
- The PoWbox leverages Kubernetes autoscaling across IOTA dedicated GPU farm and a separate cloud provider, and takes less than a second in most cases — about one-tenth of a second at MWM=9
- Users can get an API token for the IOTA PoWbox via GitHub OAuth integration, but they must have a verified GitHub account to use the PoWbox, and rate limiter will be observed and adjusted as necessary to keep the PoWbox available for everyone
- The PoWbox code has been ported to Node.js to make it more accessible to more developers, and will soon be made available on GitHub, and the repo comes complete with instructions for running via Docker or Kubernetes with a few simple commands
The source code for the PoWbox server is available, and IOTA provides a PoWbox for the IOTA testnet.
