Nervos CKB - The Common Knowledge Base
About Nervos CKB
Nervos CKB is the layer 1 of Nervos Network, a public blockchain with PoW and cell model.
Nervos project defines a suite of scalable and interoperable blockchain protocols. Nervos CKB uses those protocols to create a self-evolving distributed network with a novel economic model, data model and more.
License
Nervos CKB is released under the terms of the MIT license. See COPYING for more information or see https://opensource.org/licenses/MIT.
Development Process
This project is still in development, and it's NOT in production-ready status. The wiki also lists some known issues that we are currently working on.
The master
branch is regularly built and tested, however, it is not guaranteed to be completely stable; The develop
branch is the work branch to merge new features, and it's not stable.
The contribution workflow is described in CONTRIBUTING.md, and security policy is described in SECURITY.md. To propose new protocol or standard for Nervos, see Nervos RFC.
Build dependencies
CKB is currently tested mainly with stable-1.29.2
on Linux and Mac OSX.
We recommend installing Rust through rustup
# Get rustup from rustup.rs, then in your `ckb` folder: rustup override set 1.29.2 rustup component add rustfmt-preview rustup component add clippy-preview
Report new breakage is welcome.
You also need to get the following packages:
- Ubuntu and Debian:
sudo apt-get install git autoconf flex bison texinfo libtool pkg-config libssl-dev libclang-dev
If you are on Ubuntu 18.04, you might run into 'stdarg.h' file not found
error, this is because librocksdb-sys
fails to find the correct include path. A temporary fix until librocksdb-sys
fixes this problem is as follows:
sudo ln -s /usr/lib/gcc/x86_64-linux-gnu/7/include/stdarg.h /usr/include/stdarg.h sudo ln -s /usr/lib/gcc/x86_64-linux-gnu/7/include/stddef.h /usr/include/stddef.h
- Archlinux
sudo pacman -Sy git autoconf flex bison texinfo libtool pkg-config openssl-1.0 clang
If you get openssl related errors in compiling, try the following environment variables to specify openssl-1.0:
OPENSSL_INCLUDE_DIR=/usr/include/openssl-1.0 OPENSSL_LIB_DIR=/usr/lib/openssl-1.0 cargo build --release
- OSX:
brew install autoconf libtool
Build from source & testing
# get ckb source code git clone https://github.com/nervosnetwork/ckb.git cd ckb # build in release mode cargo build --release
You can run the full test suite, or just run a specific package test:
# Run the full suite cargo test --all # Run a specific package test cargo test -p ckb-chain
Quick Start
Start Node
Create the default runtime directory:
cp -r nodes_template/ nodes
Use the config file to start the node
target/release/ckb run
It searches config file ckb.json
, nodes/default.json
in the shell
working directory in that order. Alternatively, the argument -c
can specify
the config file used to start the node.
The default config file saves data in nodes/default/
.
Send Transaction via RPC
Find RPC port in the log output, the following command assumes 8114 is used:
curl -d '{"id": 2, "jsonrpc": "2.0", "method":"send_transaction","params": [{"version":2, "inputs":[], "outputs":[], "deps":[]}]}' \ -H 'content-type:application/json' 'http://localhost:8114'
Advanced
Run multiple nodes in different data directories.
Create the config file for new nodes, for example:
cp nodes/default.json nodes/node2.json
Update data_dir
configuration in config file to a different directory.
"data_dir": "node2"
Then start the new node using the new config file
target/release/ckb -c nodes/node2.json run
The option ckb.chain
configures the chain spec. It accepts a path to the spec JSON file. The directory nodes_template/spec
has all the pre-defined specs. Please note that nodes with different chain specs may fail to connect with each other.
The chain spec can switch between different PoW engines. Wiki has the instructions about how to configure it.
