Bitcoin address and private key generator

Bitcoin address and bitcoin address and private key generator key generator is called a hierarchical deterministic wallet, or HD wallet for short.

Bitcoin address and private key generator seed value, or master extended key, consists of a bit private key and a bit chain code, for bits in total.

The seed value should not be confused with the private keys used directly to sign Bitcoin transactions. Users are strongly advised to use HD wallets, for safety reasons: An HD wallet only needs to be backed up once typically using a seed phrase ; thereafter in the future, that single backup can consider, paragon hf sec commit deterministically regenerate the same private keys.

Because bitcoins can only be spent once, when they are spent using a private key, the private key becomes worthless.
