Kardia Release (v1.7)

What's Changed

• Fix Tx Pool Reactor (#192)
• Update default seed nodes
• Set default InBound Peers and Outbound Peers, move to configs file

Notice

• For old node running before this release, please edit the kai_config.yaml to the following changes:

1. Remove MaxPeers config

P2P:
    PrivateKey:           # private key without 0x prefix, leave blank for joining as non-validator node
    ListenAddress: tcp://0.0.0.0:3000 # IP and Port for P2P connection
    MaxPeers: 25          # maximum accepted peers

Change to

P2P:
    PrivateKey:           # private key without 0x prefix, leave blank for joining as non-validator node
    ListenAddress: tcp://0.0.0.0:3000 # IP and Port for P2P connection
    InboundPeers: 15
    OutboundPeers: 15

2. Update the following seed nodes from
