### Bech32 Algo
|
|
|
|
|
- hash = hash160(pubkey)
|
2020-10-05 10:55:10 +03:00
|
|
|
- 5-bit-words = convert-bits(8, 5, hash-atom)
|

|

### BTC pubkey -> address hashing (Hash-160)
|
2020-10-04 16:07:07 +03:00
|
|
|
Uses the example data here:
|
|
|
|
|
https://en.bitcoin.it/wiki/Technical_background_of_version_1_Bitcoin_addresses
|
|
|
|
|
|
2020-10-05 10:55:10 +03:00
|
|
|
That one starts with pubkey below. The following runs it through sha256 and ripemd160 to get Hash-160:
|
2020-10-04 17:16:35 +03:00
|

|
```
|
|
|
|
|
|
2020-10-04 16:07:07 +03:00
|
