Segwit Ephemeral Anchors

In the realm of cryptocurrency addresses, specific modifications to a two-digit code can result in different types of bech32m addresses.
For instance, changing the code to 0x4e73
generates the address bc1pfeessrawgf
, which interestingly breaks down into a predictable structure: the prefix "bc1p", followed by a segment that can vary ("fees" in this case), and concluded with a checksum. This pattern is applicable across various codes; for example, 0xffff
leads to bc1plllsqd8ech
, while setting the code at 0x0100
(which represents the number 1) results in bc1pqyqqgs7ult
. Similarly, using 0x0001
(or 256 in decimal) produces bc1pqqqs4em24r
.
The versatility in generating these addresses is further highlighted through different network prefixes. For Testnet or Signet networks, modifying the code to 0x4e73
yields an address like tb1pfees9rn5nz
, whereas for Regtest, it results in bcrt1pfeesnyr2tx
. Such variations underscore the adaptability of bech32m addresses to different blockchain environments.
For enthusiasts interested in exploring various combinations and their corresponding addresses, the Bitcoin command-line interface (CLI) tool provides a means to decode scripts through the command bitcoin-cli decodescript 51024e73
. This functionality allows users to engage with the technology hands-on, offering a bridge between theoretical knowledge and practical application in the creation and analysis of cryptocurrency addresses.
