Rust Ceramic

Implementation of the Ceramic protocol in Rust.

Current status is that the ceramic-one binary only mimics the Kubo RPC API and relies on https://github.com/ceramicnetwork/js-ceramic for the remaining logic.

Installation

The following section covers several ways one can install Rust-Ceramic contingent on the recieving environment:

MacOS

Install from Homebrew:

brew install ceramicnetwork/tap/ceramic-one

Linux - Debian-based distributions

Install a the latest release using dpkg:

# get deb.tar.gz
curl -LO https://github.com/ceramicnetwork/rust-ceramic/releases/latest/download/ceramic-one_x86_64-unknown-linux-gnu.tar.gz
# untar the Debian software package file
tar zxvf ceramic-one_x86_64-unknown-linux-gnu.tar.gz
# install with dpkg - package manager for Debian
dpkg -i ceramic-one.deb

Linux - from Source

# Install rust
curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh
# Install build tools
apt-get install -y build-essential pkg-config openssl libssl-dev unzip
# Update environment
source "$HOME/.cargo/env"
# Install protobuf
PROTOC_VERSION=3.20.1
PROTOC_ZIP=protoc-$PROTOC_VERSION-linux-x86_64.zip
curl --retry 3 --retry-max-time 90 -OL https://github.com/protocolbuffers/protobuf/releases/download/v$PROTOC_VERSION/$PROTOC_ZIP \
    && unzip -o $PROTOC_ZIP -d /usr/local bin/protoc \
    && unzip -o $PROTOC_ZIP -d /usr/local 'include/*' \
    && rm -f $PROTOC_ZIP
# Checkout rust-ceramic repo
git clone https://github.com/ceramicnetwork/rust-ceramic
# Enter repo and build
cd rust-ceramic
make build
cp ./target/release/ceramic-one /usr/local/bin/ceramic-one

Docker

Start rust-ceramic using the host network:

docker run --network=host \
  public.ecr.aws/r5b3e0r5/3box/ceramic-one:latest

Docker-Compose

1. Create a testing directory, and enter it:

mkdir ceramic-recon
cd ceramic-recon

1. Save the following docker-compose.yaml there:

version: '3.8'

services:
  ceramic-one:
    image: public.ecr.aws/r5b3e0r5/3box/ceramic-one:latest
    network_mode: "host"
    volumes:
      - ceramic-one-data:/root/.ceramic-one
volumes:
  ceramic-one-data:
    driver: local

1. Run docker-compose up -d

Usage

Running the ceramic-one binary is simply passing the daemon cli option.

# if necessary, include the path/to/the/binary e.g. /usr/local/bin/ceramic-one or ./target/release/ceramic-one
$ ceramic-one daemon

# There are many flags for the daemon CLI that can be passed directly or set as environment variables.
# See `DaemonOpts` in one/src/lib.rs for the complete list or pass the -h flag
$ ceramic-one daemon -h

# A few common options are overriding the log level:
$ RUST_LOG=warn,ceramic_one=info,ceramic_service=debug ceramic-one daemon
# Or modifying the network
$ ceramic-one daemon --network testnet-clay
$ ceramic-one daemon --network local --local-network-id 0
# Or changing where directory where all data is stored. This folder SHOULD be backed up in production
# and if you change the defaults, you MUST specify it every time you start the daemon.
$ ceramic-one daemon --store-dir ./custom-store-dir

The process honors RUST_LOG env variable for controlling its logging output. For example, to enable debug logging for code from this repo but error logging for all other code use:

Self-Anchoring

Ceramic One supports self-anchoring directly to EVM-compatible blockchains (Gnosis, Ethereum, Polygon, etc.), eliminating the need for a centralized anchor service. See anchor-evm/README.md for setup instructions.
