Bitcoin address formats and performance comparison

There are 3 types of addresses:

1. P2PKH or Legacy address (old address format) is the first version of a Bitcoin address that starts with the number "1" and has 26 to 36 characters. The average fee when sending from a P2PKH address is usually higher than when sending from a Segwit address, because transactions with outdated addresses are larger in size.
   Example: 1A1zP1eP5QGefi2DMPTfTL5SLmv7DivfNa
2. P2SH is the new address type is structured similarly to P2PKH, but starts with "3" instead of "1". P2SH provides more complex functionality than the previous type of address. In order to spend bitcoins sent via P2SH, the recipient must provide a script corresponding to the script hash and data, which makes the script true. However, all that an ordinary user needs to know is that using this type of address instead of P2PKH, the average transaction fee will be less.

3. P2WPKH or Bech32 is an advanced type of address that is used to reduce blockchain block sizes to speed up transaction response time. Addresses start with "bc1" and are longer than P2PKH and P2SH. Bech32 is the native Segwit addressing format (although P2SH can also be a Segwit address), so usually speaking about the use of Segwit addresses Bech32 is meant.
   The advantage is the lowest transaction sending fee and high processing speed.
   The disadvantage of such addresses is that not all wallets and systems support it yet.

FixedFloat uses Bech32 addresses by default, as our team is committed to introducing new technologies.

Bitcoin address performance comparison chart

For simplicity, we use the following abbreviations:
I   – P2PKH, adress starts with "1"
II  – P2SH, adress starts with "3"
III – Bech32, adress starts with "bc1"
