History

zah 6036f2e7d7 Local sim impovements (#4551 ) * Local sim impovements * Added support for running Capella and EIP-4844 simulations by downloading the correct version of Geth. * Added support for using Nimbus remote signer and Web3Signer. Use 2 out of 3 threshold signing configuration in the mainnet configuration and regular remote signing in the minimal one. * The local testnet simulation can now use a payload builder. This is currently not activated in CI due to lack of automated procedures for installing third-party relays or builders. You are adviced to use mergemock for now, but for most realistic results, we can create a simple builder based on the nimbus-eth1 codebase that will be able to propose transactions from the regular network mempool. * Start the simulation from a merged state. This would allow us to start removing pre-merge functionality such as the gossip subsciption logic. The commit also removes the merge-forcing hack installed after the TTD removal. * Consolidate all the tools used in the local simulation into a single `ncli_testnet` binary.		2023-02-23 02:10:07 +00:00

Networking

This folders hold a collection of modules to:

configure the Eth2 P2P network
discover, connect, and maintain quality Eth2 peers

Data received is handed other to the ../gossip_processing modules for validation.

Security concerns

Collusion: part of the peer selection must be kept random. This avoids peers bringing all their friends and colluding against a beacon node.
Denial-of-service: The beacon node must provide ways to handle burst of data that may come:
- from malicious nodes trying to DOS us
- from long periods of non-finality, creating lots of forks, attestations, forks
