Recover your Bitcoin Core wallet fast

DeNova Blockchain Backup quickly recovers your Bitcoin Core wallet when your local blockchain gets damaged.

Prevent lost access to your wallet

Elon Musk warns you should avoid exchange wallets "at all costs".

But the biggest risk to holding your own wallet is losing access to it. Any damage to your local blockchain can block your wallet for days. Just shutting down your machine at the wrong time is enough. Ordinary file backups don't work. It's free.

The entire Bitcoin industry relies on Bitcoin Core. But when people lose access to their full node wallet, they usually hand over their wallet to an exchange. They give the exchange their money. The Bitcoin ecosystem loses a full node and becomes less decentralized.

Ordinary system backups don't help

The blockchain architecture isn't simple. Blockchain Backup:

• Coordinates concurrent processes
• Backs up your local copy of the blockchain
• Backs up specialized Bitcoin Core metadata
• Is a simple to use web app
• Makes sure you are connecting directly from your local system
• Protects against crashes during backup or restore
• Keeps as many backups as you want

You must install Blockchain Backup before you need it. If you wait for the dreaded "resync" message from Bitcoin Core, you've already lost access to your wallet. Because the blockchain is huge, you can waste days or weeks trying to recover. To prevent this emergency, install Blockchain Backup before your blockchain is damaged. Learn more
