Sparse merkle tree rocksdb store implementation

This is a rust implementation of a sparse merkle tree store using rocksdb as the backend.

Usage

Commands

You can specify two parameters:

• -l specifies the listening address and port, the default is 127.0.0.1:10000
• -d specifies the path to the store database, the default is /tmp/smt-store

Docker

Depending on your installation environment, you may need to add sudo to obtain authorization.

Development Debugging

make docker-build
make docker-image
make docker-test

Deployment

You can pull the official dotbit image directly and run the command to start the service.

 docker run --name sub-account-store \
        --env RUST_LOG=Info \
	-d --restart always \
	-p 9130:9130 \
	-v /mnt/somedata/sub-account-store:/app/data \
	dotbitteam/sub-account-store:latest

Note that during deployment, use the -v parameter to specify the storage path on the host in order to ensure that no data is lost.

Examples

Commands

cargo run -l 127.0.0.1:10000 -d /tmp/smt-store-path
