We are pleased to announce that MultiBit HD Release 0.1 is available for download.

We'd like to take this opportunity to thank everyone who has donated funds, time and effort to help us get to this stage. It's taken us 18 months of full time effort and we're proud of what we're able to share with the Bitcoin community.

Feature summary

Here are the important capabilities of MultiBit HD:

Disaster recovery features

Everybody experiences data loss at some point. Here is how you are shielded from this using MultiBit HD:

  • you lose your password - click Restore on credentials screen and recover it from local backup with your "wallet words" (seed phrase)
  • you delete all your local backups (hard drive error) - automatic restore from cloud backup
  • you delete all your local and cloud backups (stolen laptop) - select "Restore from wallet words" and follow the instructions
  • you forget your wallet words - unlock your firesafe and retrieve the laminated paper copy you made
  • you lose your Trezor - restore the Trezor wallet from your "wallet words" and move the bitcoins to safety

Technical details

More technically minded readers will want to know that we support the following:

  • open source under modified MIT licence

  • random peer discovery (plus it will use your local Bitcoin Core if you are running one)
  • Tor support out of the box (optional)
  • Trezor support out of the box (just plug it in)
  • all data is encrypted locally using entropy gathered from your wallet words (12, 18 or 24)
  • hierarchical deterministic (HD) wallet support BIP32 and BIP44 (account 1 only in each case because it's SPV)
  • all data automatically backed up to a location of your choice (encrypted)
  • detailed transaction information
  • support for BIP21/72 links and Payment Protocol BIP70
  • multiple block explorers
  • sign/verify of Bitcoin messages - use Copy/Paste All to fill all fields in one click
