| BVER | Block model, initially U32L, now see BIP9 and so on |
| B1B1 | Two one-byte fields, fastened marker and flag values for segregated witness |
| CIVL | Compact integer, variable-length (cf varint) with little-endian worth. |
| H256 | A 256-bit hash (reversed/little-endian) |
| I64L | Signed 64-bit integer little-endian |
| NBIT | See https://bitcoin.stackexchange.com/a/57186/13866 |
| TIME | Unix time, U32L seconds since begin of 1970 UTC |
| U32L | Unsigned 32-bit integer, little-endian |
(the four-letter type-names are nonstandard, e.g. U32L is extra generally named uint32_t with endianness implied)
