Mnemonic backup

We all know the importance of keeping backups and we all know how potentially devastating it could be to loose access to all our coins. Up until now, we all have had to keep multiple backups of the ‘wallet.dat‘ file which holds our private keys to stay safe. This is potentially susceptible to data failure and data corruption. I have also kept copies of private keys and other forms of backup. Therefore in v4.1 we are introducing a more secure way to backup your wallet. We have implemented “Mnemonic seed” backup for the Spectrecoin wallet.

So what is a “Mnemonic seed” and how do they work? Firstly, a “Mnemonic seed” is a random sequence of 24 words out of a predefined 2048 words from the BIP-0039 seed word list such as the following 24 words below. I suspect many of you have encountered this before.

The mnemonic is created by following the specifications in BIP-0039 and the mnemonic can then used to generate a binary seed. This binary seed can be used later to generate all the key pairs in a deterministic wallet. Therefore, the mnemonic is all you need to keep your coins safe. This is a big improvement in security and also paves the way for possible integration into hardware wallets such as Trezor, Ledger and others. If you want to explore this further have a look at this website:

Note that there is no way to convert an old wallet to a new “Mnemonic seed” wallet. It is also important to stress that you do not have to set up a new “Mnemonic seed” wallet. The old wallet format will work fine, but the “Mnemonic seed” wallet offers better security in case of computer failure and other events that could cause a loss of your coins.

Follow the quick guide below to set up a “Mnemonic seed” wallet and transfer your coins to the new wallet. Make sure that you work in this order to complete the process. If you are unfamiliar with some or all of these steps you can find links to more detailed upgrade guides below:

You need to complete this process using a graphic UI, Windows, Mac OSX or Linux.
