Block Generators

Block generators in Chia are clvm programs that, when run with particular arguments, produce a list of coin spends. This provides opportunity to do compression by recognizing patterns and encoding.

CLVM Serialization

The standard serialization mechanism of clvm is defined here.

If you review this specification, you'll see that deserialization begins by inspecting the first byte. If the byte is 0xff, the object is a pair. If the byte is 0x00 to 0xfb, the object is an atom whose length is partially or fully encoded by this first byte.

We introduce a new puzzle, "settlement_payments", which pays out coins and make an announcement for each new coin created.

settlement_payments.cl:

(mod (coins_paid)
  ;; `coins_paid` is a list of notarized coin payments
  ;; a notarized coin payment is `(nonce puzzle_hash amount ...)`
  ;; Each notarized coin payment creates a `(CREATE_COIN puzzle_hash amount)` payment

Idempotent clarifications

Here are a bunch of changes you can make for humans only. None of these changes should change how it compiles, so you should be able to change anything in this section and compare the resultant compile. It should be identical.

reformat

I've really love an automated pretty-printer akin to "black" for python or "cargo fmt" for rust so you can write whatever mess you want and have a computer indent it so it looks nice, but I haven't been able to find one yet.
