Software Changes Overview

Software Changes that you are expected to see in the new upgrade to FoTan

The documentation is designed for Liker Land and LikeCoin v2. For information on 3ook.com and LikeCoin v3, please visit docs.3ook.com and dao.like.co.

liked & likecli

• liked and likecli commands are combined into one single command (liked).

• Key storage format changed, storage is moved into .liked, any access (including listing keys) would require user to provide the key vault password .

  • Multiple keyring backends are supported from --keyring-backend parameter, however when using Docker, only traditional file storage will be supported. You may compile standalone liked executable for other backends if needed.

• As likecli is gone, lite client does not have a standalone process anymore. API server would need to be manually enabled in app.toml from the chain node.

Transactions & Queries

• Balance is moved into the bank module, so you may need to runliked query bank balances instead of likecli query account.

• Many old APIs are deprecated. See https://v1.cosmos.network/rpc/v0.41.4 for details.

Docker setup

• In SheungWan, we used separate Docker images for root and non-root. Turns out it is not necessary, as Docker and Docker-Compose can specify the runtime user. So in FoTan the images are unified, and LIKECOIN_UID is introduced in .env.

• Variables (seed nodes, users) are specified in the .env file.

• Commands are now run by docker-compose run , so configs in docker-compose.yml (e.g. volumes, users) could be reused. no need to re-type every time.

Scripts

• Scripts are rewritten and combined with Docker Compose profiles (We now require Docker Compose ≥1.28).
