genesis-populate

Performance of our node varies drastically depending on the size of the trie it operates with. As the baseline, we agreed to take the trie roughly equivalent to the trie of Ethereum (as of October 2019) in its complexity. We achieve it by populating trie with 80M accounts and uploading a smart contract to each of them. We also make sure the trie does not compress the subtrees due to similar account names. We then use this trie for benchmarking, loadtesting, and estimating system parameters.

To start node with 20k accounts first create configs:

cargo run --package neard --bin neard -- init --test-seed=alice.near --account-id=test.near --fast

Then create state dump with how many accounts you want:

cargo run --package genesis-populate --bin genesis-populate -- --additional-accounts-num=20000

This will produce state_dump and genesis_roots files in home directory of the node, you can also use --home on all commands here to specify an absolute path to a home directory to use.

Then start a single local node:

cargo run --package neard --bin neard -- run --boot-nodes=
