@ -48,13 +48,10 @@ contents of a memo. It does not define consensus requirements.
+ Interpret the next few bytes (1 to 9 of them) as a 64-bit unsigned variable-length
integer [#Bitcoin-CompactSize]_, and use it as an arbitrary application-defined
"type" field.
+ Interpret the next bytes (1 to 2 of them) as a 16-bit unsigned ULEB, and use it as
the length field. (The length can be at most 510 bytes due to the overall memo
length, and that is why the length field can only be 1 or 2 bytes.)
+ Interpret the next 1 or 2 bytes as a CompactSize value constrained to the range 0..510, and use
the resulting value as the length of the remaining data.
+ If 1 + the number bytes used for the type field + the number of bytes used for the
length field + the length > 512 then error out, i.e. do not do any further
processing of the memo, and do not return any information about the memo to the
caller other than the fact that it was incorrectly formatted.
length field + the length > 512 then report an error.
+ Inspect the padding after the end of the indicated length, and if it
contains anything other than bytes of value 0x00 then report an error.
+ Return to the caller a 3-tuple of the following data:
