Version upgrade changes

  1. Add new RPC interface
  2. Fix some issue about ERC721

Warning

This version fixes the issue related to ERC721, which involves the change of the Wormhole rule, and all nodes must be forced to upgrade to the version released this time (0.2.1). At the same time, nodes below version 0.2.1 will no longer be supported, and old nodes will not be able to provide accurate Wormhole trading information due to changes in consensus rules.

Bitcoin-Abc compatible

The Wormhole 0.2.1 node is compatible with the Bitcoin-Abc 0.18.2 version. The Wormhole node can also be used as a Bitcoin-Abc node to support all functions of the Bitcoin-Abc node.
