This reduces the maximum penalty for voting after the grace period by
roughly 50%. This new value was derived from looking at the effects
that TVC at max credits 8 would have for recent epochs (500+) and
noting that the effect was a bit extreme, up to and exceeding 10%
"bonus" for faster voters. This change reduces that maximum bonus by
roughly half.
In addition, the TVC feature key has been changed.
`sha2` and `sha3` crates already moved to `generic-array` 0.14.7,
which means that we can safely convert the hash result to a sized
array just by calling `finalize().into()`, which doesn't return
any errors.
The typo in the function names convert_edianness_64 and convert_edianness_128 has been corrected to convert_endianness_64 and convert_endianness_128 respectively.
* implement a custom parser for `VoteState` which is usuable in a bpf context
* derive or impl `Arbitrary` for `VoteStateVersions` and its component types, for test builds only
That new release contains an important change which prevents a
potential DDoS.
* Lightprotocol/light-poseidon#32
Invoking `from_bytes_be` function light-poseidon 0.1.1 inverts all
the inputs before performing a check whether their length exceeds
the modulus of the prime field. Therefore, it was prone to an
attack, where a mailicious user could submit long byte slices just
to DDoS the validator, being stuck on inverting large byte sequences.
The update and mentioned change fixes the same issue as #33363 aims
to address.
The new release contains also few other less important changes like:
* Lightprotocol/light-poseidon#37
* Lightprotocol/light-poseidon#38
* Lightprotocol/light-poseidon#39
