5 years ago Hi, ggarri ~ At present, what is the standard for lightchain synchronization? How do you know that multiple lightchain nodes are synchronized? Can each synchronized node like Etheneum geth query each other's account balance?

5 years ago In lightchain we are using Tendermint consensus protocol, therefore every information regarding to the consensus status, including synchronization is exposed via Tendermint RPC endpoints (https://tendermint.com/rpc/#). By default, on every lightchain node, the tendermint rpc is bind to the port 127.0.0.0:26657
At the minute you could fetch the current local synchronization status by doing a http call to the url localhost:26657/status (see more info here).
This issue, and future ongoing issues, are intending to implement a smooth and seamless integration of tendermint rpc api into geth native rpc api calls.

5 years ago ok~ thank you, In addition, I would like to consult, I use Tendermint to observe the log, it will show the block record, but I did not show the block record when using the lightchain-sirius mode, I understand that the lightchain integrates the tendermint.

I started two Tendermints and implemented synchronization. Their block num are consistent
but Lightchain but did not see the block log.
In order to provide a better integration of the PoC protocol in Lightchain we should provide support for the admin method
addPeer(). See more information about the expected behaviour at the official ethereum doc https://github.com/ethereum/go-ethereum/wiki/Connecting-to-the-network
