A wallet hosts the details of the key pair making transacting cryptocurrency possible. WalletsĪ number of technologies known as wallets exist that store the key value pair of private and public key known as wallets. (Words are easier to memorize than numerals.) When online, exchange and hardware wallets are generated using random numbers, and a seed phrase is asked to be recorded by the user, hence when access to the wallet becomes misplaced, damaged or compromised, the seed phrase can be used to re-access the wallet and associated keys and cryptocurrency in toto. In modern convention a seed phrase is now utilised which is a random 12 to 24 (or even greater) list of dictionary words which is an unencrypted form of the private key. The number of possible wallets in any cryptocurrency cryptography is slightly less than the number of atoms in the universe, a number so high that duplicating or hacking a certain key would be inconceivable. However, this possibility is negated because the theoretical probability of two or more private keys being the same is extremely low.

The blockchain will only record the transaction of the public address when cryptocurrency is sent to it, thus recording in the blockchain ledger the transaction of the public address.Ĭollision (two or more wallets having the same private key) is theoretically possible, since keys can be generated without being used for transactions, and are therefore offline until recorded in the blockchain ledger. The private key and public key pair (known as an address) are not known by the blockchain or anyone else. Up to this stage no computer or electronic device is required and all key pairs can be mathematically derived and written down by hand. The private key is utilised by the owner to access and send cryptocurrency and is private to the owner, whereas the public key is to be shared to any third party to receive cryptocurrency. A public key is then generated from the private key using whichever cryptographic algorithm requirements are required. The number is then converted to a private key using the specific requirements of the cryptocurrency cryptography algorithm requirement. Technology Private and public key generationĪ cryptocurrency wallet works by a theoretical or random number being generated and used with a length that depends on the algorithm size of the cryptocurrency's technology requirements. 2.5.2 Hierarchical deterministic wallet.1.5 Crypto wallets vis-à-vis dapp browsers.
