Bitcoin addresses
Each transaction has a public address (derived from the sender's public key) which can be used to send bitcoins to the recipient. Addresses are simply: a hash of the public key. Bitcoin addresses are like traditional mailing addresses: they are used to receive payments.
For various technical reasons, bitcoin addresses are "pointers" to secret keys, and they can be long and difficult to remember. By contrast, web service provider names can be short, and "friendly" such as in webmail. For that reason, many consider bitcoin addresses to be the natural mapping of public key hashes to human-friendly text.
Address prefixes
Sub-addresses (see below) are compact and easy to remember, but they are used primarily for vanity addresses (rather than actual bitcoins). https://volhovstroyka.ru/ Prefixes, in contrast, can be useful for saving space when sending to many recipients, or for grouping similar transactions. Prefixes are an optional part of the address syntax, and can be used as described below.
Shortened addresses
It is possible to create Bitcoin addresses that are easy to remember by using only a sub-address and a suffix. This allows users to have unique addresses without typing the full address.
Suffix
There are three types of bitcoin address suffixes:
The standard Bitcoin address prefix has three components: a 1-byte message prefix, an n-byte message checksum, and a 1-byte variable-length fraction.
A script-pubkey prefix is appended in front of the data. There is also a legacy script-pubkey suffix that creates a legacy address.
A compact address scheme (BIP32) offers users more options, including segwit. See below for more details.
Script-Pubkey
Bitcoin addresses generated with a script-pubkey prefix are additionally the result of an OP_CHECKSIG or OP_CHECKMULTISIG or OP_HASH160 OP_EQUALVERIFY OP_CHECKSIG or OP
