Key changes/features

  • Metadata

Bnb currently is swarmed with fake nodes which have negative impact for overall performance of the chain. Metadata can be used to filter the most basic nodes due to their inactivity or spamming actions.

The change is reflected in method admin_peers as extra field called metadata. Ref: https://geth.ethereum.org/docs/rpc/ns-admin Example:

curl --data '{"method":"admin_peers","params":[],"id":1,"jsonrpc":"2.0"}' -H "Content-Type: application/json" -X POST localhost:PORT
stat description
value total amount of received packets from peer
cache hashes of recent transactions/blocks
lastActivity timestamp of packet
connectedAt timestamp of peer connection

By default only last 10 actions are being cached. The value can be specified with metadata.cache.size flag

  • Censorship

Fake nodes and toxic bots on the network can be additionaly censored by forbiding specific accounts from propagation. As node operation you will be still receiving the data of such accounts but the transactions won't be relayed to connected peers.

function description
blacklistedPropagation returns currently blocked addressess
unblacklistPropagation unblocks address if blocked
blacklistPropagation blocks address
Unblock address:
curl --data '{"method":"mev_unblacklistPropagation","params":["address"],"id":1,"jsonrpc":"2.0"}' -H "Content-Type: application/json" -X POST localhost:PORT

Block address:
curl --data '{"method":"mev_blacklistPropagation","params":["address"],"id":1,"jsonrpc":"2.0"}' -H "Content-Type: application/json" -X POST localhost:PORT

Check addresses:
curl --data '{"method":"mev_blacklistedPropagation","params":[],"id":1,"jsonrpc":"2.0"}' -H "Content-Type: application/json" -X POST localhost:PORT
Note: Those functions have been added to "mev" module. If you have http/ws.api flag enabled then you need to also speficy that module, eg. --http.api "eth,admin,mev".
  • Openssl

Encryption/Decryption can be optionally set to use openssl implementation. Openssl AES CTR is faster and uses less resources in comparison to golang native implementation.

In order to use that feature make sure that openssl installed.
In order to enable new feature set --openssl flag. By default this feature is disabled.
