Yes! Private keys when denoted in base 58 check format have different values in compressed and uncompressed form. This was done to ensure that the clients don't get confused as to which address to map (compressed or uncompressed). The point being: WIF format for every hex private key are different in compressed and uncompressed form. Bitcoin Vanity Address Generator 1. Select the address format. Bitcoin legacy address; begins with 1; allowed characters: , a-z, A-Z; Public Key (WIF compressed) Private Key (WIF compressed) Adopt public key Cancel. I would be very happy about a small donation for further developments! 17 rows · Bitcoin address format Bitcoin address is an identifier (like account number), starting with 1, .

Computer Languages. General Knowledge and Current Affairs. Popular Posts. Blockchain-based currencies use encoded strings, which are in a Base58Check encoding with the exception of Bech32 encodings. The encoding includes a prefix traditionally a single version byte , which affects the leading symbol s in the encoded result. The following is a list of some prefixes which are in use in the reference Bitcoin codebase.
Note that private keys for compressed and uncompressed bitcoin public keys use the same version byte. The reason for the compressed form starting with a different character is because a 0x01 byte is appended to the private key before base58 encoding. The following table shows the leading symbol s and address length s for bit hashes for each of the possible decimal version values:. The result is 33 bytes long. Sign up to join this community.

But it is always disallowed to try to read a wallet. That's a permitted break. You could still manually extract the case, uncompress them, and put them into the earlier form if you had to.
But that kind of compatibility is not supported. You can't go back with a newer wallet file unless you translate the data. To answer your other question, only in the wallet. Compressed keys aren't yet supported anywhere else because that would be a protocol-breaking change. The advantage is mainly for the blockchain and the network, as transactions will be a bit smaller now. It's 33 bytes instead of 65, by the way. I have a problem understanding it : I have an uncompressed private key, I enter it in bitaddress.
On one I have one million dollar, on the other 0. And they both come from the same private key.
