Antoine Poinsot	7345aa60d9	policy: add a function to get the virtual transaction size ... It's very useful to Bitcoin applications, and especially "L2" ones, to effectively compute feerates. Currently (and this is very unlikely to change) bitcoind nodes compute the virtual size as a rounded-up division of the size in witness units by 4, with a penalty for transactions that are essentially >5% full of sigops.

Antoine Poinsot	2b777485fa	policy: introduce p2p constants from the reference implementation ... This introduces some constants defined by Bitcoin Core which as a consequence define some network rules in a new 'policy' module. Only some were picked, which are very unlikely to change. Nonetheless a Warning has been put in the module documentation. Script-level constants are left into rust-miniscript where they are already defined (src/miniscript/limits.rs).	2021-05-18 14:52:56 +02:00
