Setup and run

Start one starknet (bootstrap) node and one Malachite node:

• Starknet code

git clone https://github.com/starkware-libs/sequencer.git
cd sequencer
git co shahak/for_informalsystems/mock_batcher_to_return_empty_proposals

• export NUM_VALIDATORS=3
• Start the starkent bootstrap node with:

cargo run --bin starknet_sequencer_node -- --chain_id MY_CUSTOM_CHAIN_ID --eth_fee_token_address 0x1001 --strk_fee_token_address 0x1002 --recorder_url http://invalid_address.com --base_layer_config.node_url http://invalid_address.com --batcher_config.storage.db_config.path_prefix ./batcher_data --class_manager_config.class_storage_config.class_hash_storage_config.path_prefix ./class_manager_data --state_sync_config.storage_config.db_config.path_prefix ./sync_data --consensus_manager_config.network_config.tcp_port 27000 --mempool_p2p_config.network_config.tcp_port 11000 --state_sync_config.network_config.tcp_port 12000 --http_server_config.port 13000 --monitoring_endpoint_config.port 14000 --consensus_manager_config.network_config.secret_key 0x1111111111111111111111111111111111111111111111111111111111111111 --state_sync_config.network_config.secret_key 0x2222222222222222222222222222222222222222222222222222222222222222 --validator_id 0x64 --consensus_manager_config.context_config.num_validators $NUM_VALIDATORS

• Initialize a 3 node malachite network:

cargo run --bin informalsystems-malachitebft-starknet-app -- testnet --home nodes --nodes 3

• Start malachite node 2:

cargo run --bin informalsystems-malachitebft-starknet-app -q -- start --home nodes/2

Current state

• Starknet bootstrap closing connection:

Looks like they use Ed25519 and not ECDSA: https://github.com/starkware-libs/sequencer/blob/875926b20f629c6e05e1dfbf69bf81cdc8044dee/crates/papyrus_network/src/network_manager/mod.rs#L685-L690

I can do the switch to Ed25519, but will keep the ECDSA implementation around in case we ever need to switch back to it.
