NKN Testnet v0.3.7-alpha

• Add chord id to each sigchain element and use it to check block proposer. This prevents multiple nodes sharing the same wallet from proposing multiple blocks.
• Fix Json api server CORS not working

NKN Testnet v0.3.6-alpha

• Fix the bugs that will cause Chord topology not correct or even crash
• Fix the bugs that will cause node to be deadlocked
• Fix the bugs that will open too many connections
• Fix the bugs that will make node stuck in sync state
• Tons of minor bug fix and improvements

NKN Testnet v0.3.5-alpha

1. bug fixes for chord networking, such as deadlock and concurrent access
2. bug fixes for transaction relay
3. unify node ID to chord ID

NKN Testnet v0.3.4-alpha

Bug fix:

• Add timeout for Chord inbound connections to avoid port leaking
• Broadcast transactions to all neighbors rather than persistfinished

NKN Testnet v0.3.3-alpha

Fix the rare bug that nil pointer error will crash the node in FindSuccessors

NKN Testnet v0.3.2-alpha

1. Fix received connection not closing bug
2. Handle all nodes restart logic, when no sigchain in system the block proposer will be changed based on timeout.

NKN Testnet v0.3.1-alpha

• Limit the max number of concurrent goroutines to prevent uncontrolled memory usage.
• Fix incoming tcp connection not closed to prevent tcp port leaking.
• A few other bug fixes.
