Welcome to Ontology's source code repository!
Ontology is dedicated to develop a high-performance blockchain infrastructure which is customizable to different business requirements.
Prerequisites for getting started with development on the Ontology networks are:
- Mainstream coding and development experience
- Understanding of your business scenario/requirements
- NO need for previous Blockchain Engineer experience
The Ontology core tech team, the community and the ecosystem can all support you in development. MainNet, TestNet, SmartX and a Docker imange for Ontology, SmartX and Ontology Explorer combined makes it easy to start.
Ontology makes getting started easier!
The code is currently Alpha phase of the release life cycle, but rapidly under development for Beta. The master code may be unstable, but stable versions can be found under the release page.
We sincerely welcome developers to Ontology.
- Scalable lightweight universal smart contract

- Crosschain interactive protocol (processing)
- Multiple encryption algorithm support
- Highly optimized transaction processing speed
- P2P link layer encryption (optional module)
- Multiple consensus algorithm support (VBFT/DBFT/RBFT/SBFT/PoW)
- Quick block generation time
- Build development environment
- Get Ontology
- Run ontology
- Some example
- Contributions
- Open source community
- License
The requirements to build Ontology are:
- Golang version 1.9 or later
- Glide (a third party package management tool)
- Properly configured Go language environment
- Golang supported operating system
-
You can download latest ontology binary file with
curl https://dev.ont.io/ontology_install | sh. -
You can download other versions at release page.
Clone the Ontology repository into the appropriate $GOPATH/src/github.com/ontio directory.
$ git clone https://github.com/ontio/ontology.git
or
$ go get github.com/ontio/ontology
Fetch the dependent third party packages with glide.
$ cd $GOPATH/src/github.com/ontio/ontology
$ glide install
Build the source code with make.
$ make all
After building the source code sucessfully, you should see two executable programs:
ontology: the node program/command line program for node controltools/sigsvr: (optional) Ontology Signature Server - sigsvr is a rpc server for signing transactions for some special requirements. Detailed docs can be found at link
You can run Ontology in four different modes:
- MainNet (./ontology)
- TestNet (./ontology --networkid 2)
- Testmode (./ontology --testmode)
- Docker
E.g. for Windows (64-bit), use command promt and cd to the dirctory where you installed the Ontology release, then type start ontology-windows-amd64.exe --networkid 2. This will sync to TestNet and you can explore further by the help command ontology-windows-amd64.exe --networkid 2 help.
Run ontology directly
./ontology
Then you can connect to ontology MainNet.
Run ontology directly
./ontology --networkid 2
Then you can connect to ontology TestNet
Create a directory on the host and store the following files in the directory:
- Node program
ontology - Wallet file
wallet.dat(wallet.datcan be generated by./ontology account add -d)
Run command $ ./ontology --testmode can start single-host test net.
Here's a example of single-host configuration:
-
Directory structure
$ tree └── ontology ├── ontology └── wallet.dat
Please ensure there is a docker environment in your machine.
-
make docker image
- In the root directory of source code, run
make docker, it will make ontology image in docker.
- In the root directory of source code, run
-
run ontology image
-
Use command
docker run ontio/ontologyto run ontology； -
If you need to allow interactive keyboard input while the image is running, you can use the
docker run -ti ontio/ontologycommand to start the image; -
If you need to keep the data generated by image at runtime, you can refer to the data persistence function of docker (e.g. valume);
-
If you need to add ontology parameters, you can add them directly after
docker run ontio/ontologysuch asdocker run ontio/ontology --networkid 2. The parameters of ontology command line refer to here.

TxHash:437bff5dee9a1894ad421d55b8c70a2b7f34c574de0225046531e32faa1f94ceTxHash is the transfer transaction hash, and we can query a transfer result by the TxHash. Due to block time, the transfer transaction will not be executed before the block is generated and added.
If you want to transfer ONG, just add --asset=ong flag.
Note that ONT is an integer and has no decimals, whereas ONG has 9 decimals. For detailed info please read Everything you need to know about ONG

Index is the sequence number of a particular account in the wallet. The index starts from 1, and the label is the unique alias of an account in the wallet.

Please open a pull request with a signed commit. We appreciate your help! You can also send your code as email to the developer mailing list. You're welcome to join the Ontology mailing list or developer forum.
Please provide detailed submission information when you want to contribute code for this project. The format is as follows:
Header line: explain the commit in one line (use the imperative).
Body of commit message is a few lines of text, explaining things in more detail, possibly giving some background about the issue being fixed, etc.
The body of the commit message can be several paragraphs. Please do proper word-wrap and keep columns shorter than 74 characters or so. That way "git log" will show things nicely even when it is indented.
Make sure you explain your solution and why you are doing what you are doing, as opposed to describing what you are doing. Reviewers and your future self can read the patch, but might not understand why a particular solution was implemented.
