Summary

Support compatibility with the Cosmos Query APIs.

proto/cosmos/base/tendermint/v1beta1/query.proto

• /cosmos/base/tendermint/v1beta1/node_info
• /cosmos/base/tendermint/v1beta1/syncing
• /cosmos/base/tendermint/v1beta1/blocks/latest
• /cosmos/base/tendermint/v1beta1/blocks/{height}
• /cosmos/base/tendermint/v1beta1/validatorsets/latest
• /cosmos/base/tendermint/v1beta1/validatorsets/{height}

proto/cosmos/tx/v1beta1/service.proto

• /cosmos/tx/v1beta1/txs

Problem Definition

The some query apis are not supported in finschia. So we cannot use any cosmos infra without modification because it makes a compatibility problem with cosmos. The basic problem is difference the block type between tendermint and ostracon. A entropy data was added more in ostracon. So I think we can convert it for tendermint.
