Questions tagged [mnemonic-seed]

A way of writing down a small set of dictionary words from which a seed-number can be recreated. This allows a wallet to be recreated from a saved phrase after the wallet has been lost or destroyed.

Mostly BIP39, an open standard for encoding a seed as a series of common words, but also collects other methodologies.

Is there a reason to why Bitcoin Core does not implement BIP39?

Is there a specific reason to why BIP39 isn't added to Bitcoin Core? Seems very trivial to add and am confused to why it isn't there.

Practical way to split a bip39 seed into a 2 out of 3 factor auth?

I want to keep off-site paper-backups of my seed, but that increases the risk of a physical attack. Can I somehow split my Mnemonic Code into three parts that I only need two of to recover my trezor?

Is the Electrum seed compatible with other wallets?

Apologies if this is a simple question - a newbie here! I'm trying to understand backups. If I use Electrum to make a back up (including the 12 word seed password), will I then need to use Electrum to restore my BTC/ or can I use a different piece…

BIP39 Manual Phrase Calculations - How are Multiple checksums valid?

Need some help understanding the math regarding why multiple checksums work for mnemonic phrase generation (BIP39). Let's assume a 12 word passphrase. If we divide the 2048 wordlist into groups of 16 ... exactly 1 word out of 16 word "block" will be…

Does BIP39 mnemonic construction avoid repeating words?

Will all 24 words of a seed-phrase be unique by specification? Or is it possible for a word to occupy two positions (ie the word "tool" is #8 AND #20 in a valid, securely generated seed)

How to restore wallet from 15-word seed mnemonic?

The wallet was created around Feb 2013, using unknown wallet software. All that is known is a passprase, and 15 words. I suspect the passphrase was used to encrypt the wallet, and is probably irrelevant here, since the wallet file itself is…

Will Electrum mnemonic seeds be forward compatible with all future versions of Electrum?

If I use the newest version of Electrum (2.6.4) to create a mnemonic seed and the current source code (2.6.4) later becomes unavailable, will I be still able to use a mnemonic seed I create now with all future version of Electrum? I know that…

How to generate specific private keys from 12-word backup and wallet address?

A single seed can lead to billions of addresses. Some wallets are unable to scan and find all used addresses. Is it a way to infer the private key from 12-word backup and wallet ID / (public key). It seems the only way to restore my balance is based…

Pros/Cons/Limitations of Mnemonic Phrases - BIP39

BIP39 mnemonic phrases replace considerations about how to store one private key, with considerations about how to store the seed to a series of private keys. The idea is that the private keys are hard to remember, worse to write down, and prone to…

What's the relationship between SLIP39 and BIP39?

Trezor's SLIP39 makes it possible to apply Shamir's secret sharing to a Bitcoin wallet seed. How do SLIP39 and BIP39 relate to each other? I.e. it seems possible to derive SLIP39 from BIP39 words but this is messy, and deriving BIP39 from SLIP39 is…

How many combinations are there from the BIP32 mnemonic list?

As I understand for BIP32. There are 2048 words. 12 words would give you 2048^12 combinations. However, not all combinations are valid because of the checksum, so how do i calculate the actual space?

How to generate recovery phrase from private key

I created a brain wallet with a non standard phrase. So I have that, the private and public keys. Now this wallet app wants a 12 word recovery phrase to set up the wallet. How can I convert what I have into a 12-word phrase that it can use?

I am new to the whole Bitcoin thing, and I am having my first attempt almost going sour. I lost where I created my wallet. I have my Bitcoin address and only 11 of my mnemonic seed phrase words (of 12). I attempted using a word I thought was it and…

Recovering a HD wallet from a partial seed phrase

I am attempting to help recover a wallet where the owner only wrote down 11 of the 12 words in the seed phrase. Initially, I thought the task would be a quick and well-defined, but it appears to be a bit more complex than I assumed, and reference…

How much entropy is lost alphabetising your mnemonics?

Yes I know this is a horrible idea and not BIP39 compliant, but please help satisfy my curiosity with this "thought experiment" and applied maths exercise. Two questions, one for 12 words, the other for 24. Assuming "perfectly random" entropy to…
