// this file implements the explorer for DERO blockchain
// this needs only RPC access
// NOTE: Only use data exported from within the RPC interface, do direct use of exported variables  fom packages
// NOTE: we can use structs defined within the RPCserver package
// This is being developed to track down and confirm some bugs
// NOTE: This is NO longer entirely compliant with the xyz RPC interface ( the pool part is not compliant), currently and can be used as it for their chain,
// atleast for the last 1 year
