  • Buterin [2017] (†818 s.v. "History"): The "state" in Bitcoin is the collection of all coins (technically, "unspent transaction outputs" or UTXO) that have been minted and not yet spent, with each UTXO having a denomination and an owner (defined by a 20-byte address which is essentially a cryptographic public key[1]). (†2350)
  • Chuen (ed) 20156 (†855 p.21): Bitcoin … uses an asymmetrical algorithm that generates two separate but asymmetrically linked keys: a public key and a private key. The keys are asymmetrical in the sense that the public key is derived from the private key but it is computationally impossible to obtain a private key from a public key. … The public key is publicly accessible; in Bitcoin, it is used as the Bitcoin address to and from which payments are sent. (†2385)
  • Wood 2014 (†803 p.19): Where p(u) is the public key, assumed to be a byte array of size 64 (formed from the concatenation of two positive integers each< 2^256) and pr is the private key, a byte array of size 32 (or a single positive integer in the aforementioned range). (†2336)
