Proposed solution:

• a Go interface is encoded as a top-level Proto3 message. In the example below, the Animal go interface is represented by a Animal proto3 message.

type Animal interface
type Dog struct
type Cat struct
type House struct {

function handleConnCloseTry()
  {state, version, counterpartyIdentifier, rootOfTrust} = Get(identifier)
  assert(state == OPEN)
  assert(identifierCounterparty == counterpartyIdentifier)
  assert(verify(roofOfTrust, proofInit, (counterpartyIdentifier, TRYCLOSE)))
  state = CLOSED
  Set(identifier, (state, version, counterpartyIdentifier, rootOfTrust))

Summary

• Agree on a plan to set up a testnet using the Cosmos SDK v0.34.0 release, along with mainnet conditions, plus transfer enablement and increased block size, as a testing ground.

• After this proposal is passed and after successful testing, and after the software Git hash for v0.34.0 has been finalized, conduct a second proposal which includes the specific Git hash, using expedited rules to determine acceptance.

   // ApplyBlock executes the block, updates state w/ ABCI responses, then commits and updates the mempool atomically, then saves state
 - execBlockOnProxyApp should return relevant ABCI responses
 - Between s.ExecBlock and s.CommitStateUpdateMempool, add a function to save ABI responses, 's.SaveABCIResponses'. Make the ABCI responses a simple field of state.State. Make it a pointer, and have State.Copy() just copy the pointer -- ABCI responses are not mutable.
 - Move call to 's.SetBlockAndValidators' to between s.SaveABCIResponses and s.CommitStateUpdateMempool.  Also move calls to 'updateValidators' and 'IncrementAccum' into s.SetBlockAndValidators.  Change s.SetBlockAndValidators to include ABCI responses as arguments.
 - After s.CommitStateUpdateMempool, save the state.
* In state/state.go
 - Change 'updated at end of ExecBlock' to 'updated at end of SetBlockAndValidators'
