An encoding method that converts cryptocurrency addresses into ASCII text that can be manually copied without making mistakes. Base58 uses all the numeric and alphabetic characters except zero, upper case O, lower case L and the digit 1, which are error-prone character pairs (0 is confused with O, and I with 1). Although copy and paste is always recommended, there are times when crypto addresses have to be typed in manually. See
Base64 and
crypto glossary.
A Base58 Bitcoin Address
Bitcoin addresses begin with a 1 or 3, followed by up to 33 alphanumeric characters. Notice that after the leading "1" in this example, there are no 0s or 1s and no capital "O" or lower case "L" letters in the address. See
