Integrate `hashtree` for better hashing performance

2

https://github.com/status-im/nim-ssz-serialization/pull/35 brings in https://github.com/prysmaticlabs/hashtree as a supported backend for SHA256, giving a nice little performance boost to all `hash_tree_root` calls on supported platforms / compilers. Expected gains are on the...

Allow using 0 to auto-select tcp/udp port

2

Specifying 0 as port should make nimbus let the OS pick a port and subsequently use it in ENR/libp2p/etc See also https://github.com/waku-org/nwaku/pull/2125

Loading the serialized signature in attestation currently makes up around 15-20% of CPU usage on the main thread - since the taskpool has become async, we could offload the loading...

avoid attestation queue in fork choice

2

https://github.com/status-im/nimbus-eth2/blob/d1713031338f4976fdf115721136f9620598afaa/beacon_chain/fork_choice/fork_choice.nim#L232 currently enqueues attestations "from the future" with respect to the current fork choice time. However, this queue is not necessary: only attestations from the "current" slot end up on...

The `unviable` field in the quarantine is used to discover block histories that are known not to be worth pursuing - this can happen either because finalization permanently cuts off...

We know from the blocks we process what the current execution block number (or request to the execution client) is so we can use this to provide a %-done of...

Buffer incoming attestations/syncmsgs/etc for which the block has still not arrive

1

Because of network delays as async validation, attestations and other small messages may arrive earlier than what we anticipate for the block - we should buffer such attestations and validate...
