# State transition, as described in
|
|
# https://github.com/ethereum/consensus-specs/blob/v1.4.0-beta.7/specs/phase0/beacon-chain.md#beacon-chain-state-transition-function
|
|
#
|
|
# The entry point is `state_transition` which is at the bottom of the file!
|
|
#
|
|
# General notes about the code:
|
|
# * Weird styling - the sections taken from the spec use python styling while
|
|
# the others use NEP-1 - helps grepping identifiers in spec
|
|
# * When updating the code, add TODO sections to mark where there are clear
|
|
# improvements to be made - other than that, keep things similar to spec unless
|
|
# motivated by security or performance considerations
|
|
#
|
|
# Performance notes:
|
|
# * The state transition is used in two contexts: to verify that incoming blocks
|
|
# are correct and to replay existing blocks from database. Incoming blocks
|
|
# are processed one-by-one while replay happens multiple blocks at a time.
|
|
# * Although signature verification is the slowest operation in the state
|
|
# state transition, we skip it during replay - this is also when we repeatedly
|
|
# call the state transition, making the non-signature part of the code
|
|
# important from a performance point of view.
|
|
# * It's important to start with a prefilled cache - generating the shuffled
|
|
# list of active validators is generally very slow.
|
|
# * Throughout, the code is affected by inefficient for loop codegen, meaning
|
|
# that we have to iterate over indices and pick out the value manually:
|
|
# https://github.com/nim-lang/Nim/issues/14421
|
|
# * Throughout, we're affected by inefficient `let` borrowing, meaning we
|
|
# often have to take the address of a sequence item due to the above - look
|
|
# for `let ... = unsafeAddr sequence[idx]`
|
|
# * Throughout, we're affected by the overloading rules that prefer a `var`
|
|
# overload to a non-var overload - look for `asSeq()` - when the `var`
|
|
# overload is used, the hash tree cache is cleared, which, aside from being
|
|
# slow itself, causes additional processing to recalculate the Merkle tree.
