another direction is to research if we can port the snappyjs implementation into assembly script since the interface is similar to `as-sha256`

figured out that the issue happened with contabo and hetzner cloud provider, not with my local environment, so not sure what we can do here. Is it something related to...

Right now we use sync apis in some places which block the event loop - Uncompress gossipsub messages, see https://github.com/ChainSafe/lodestar/issues/4170 - Encrypt/decrypt libp2p connection in libp2p-noise, see https://github.com/ChainSafe/lodestar/issues/4140 - gossipsub...

the state transition takes 1s-2s depending on the node so at least it'll take that amount of time for the node to finish the api when that happens

For more information, `uint8arraylist` is not a direct dependency of js-libp2p, it's from ``` - "_project_#it-handshake#it-reader" depends on it - Hoisted from "_project_#it-handshake#it-reader#uint8arraylist" - Hoisted from "_project_#@lodestar#beacon-node#@chainsafe#libp2p-noise#uint8arraylist" - Hoisted from...
