Welcome to Ontology's source code library!
Ontology is dedicated to creating a modularized, freely configurable, interoperable cross-chain, high-performance, and horizontally scalable blockchain infrastructure system. Ontology makes deploying and invoking decentralized applications easier.
The code is currently alpha quality, but is in the process of rapid development. The master code may be unstable; stable versions can be downloaded in the release page.
The public test network is described below. We sincerely welcome and hope more developers join Ontology.
- Scalable lightweight universal smart contract
- Scalable WASM contract support
- 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
- Server deployment
- 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
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
After building the source code sucessfully, you should see two executable programs:
ontology
: the node program/command line program for node control
You can download at release page.
To run Ontology successfully, nodes can be deployed by two ways:
- Public test network Polaris sync node deployment
- Single-host deployment
- Multi-hosts deployment
1.Create account
-
Through command line program, create wallet wallet.dat needed for node implementation.
$ ./ontology account add -d use default value for all options Enter a password for encrypting the private key: Re-enter password: Create account successfully. Address: TA9TVuR4Ynn4VotfpExY5SaEy8a99obFPr Public key: 120202a1cfbe3a0a04183d6c25ceff1e34957ace6e4899e4361c2e1a2bc3c817f90936 Signature scheme: SHA256withECDSA
Here's a example of host configuration:
Directory structure
$ tree └── ontology ├── ontology └── wallet.dat
2.Start ontology
PS: There is no need of config.json file, will use the default setting.
NOTE: The format of wallet file has been changed. Old wallets can not be used now. Please generate new wallet.
Create a directory on the host and store the following files in the directory:
- Default configuration file
config.json
- Node program + Node control program
ontology
- Wallet file
wallet.dat
, copy the contents of the configuration file config-solo.config in the root directory to config.json and start the node. - Edit the config.json file and replace the bookkeeper entries with the public key of your wallet (created above). Use
$ ./ontology account list -v
to get your public key.
Here's a example of single-host configuration:
-
Directory structure
$ tree └── ontology ├── config.json ├── ontology └── wallet.dat
-
Set bookkeepers in the config.json file:
"Bookkeepers": [ "(public key of your account)1202021c6750d2c5d99813997438cee0740b04a73e42664c444e778e001196eed96c9d" ],
We can perform a quick deployment by modifying the default configuration file config.json
.
-
Copy related file into target host, including:
- Default configuration file
config.json
- Node program
ontology
- Default configuration file
-
Set the network connection port number for each node (recommend using the default port configuration, instead of modifying)
NodePort
is P2P connection port number (default: 20338)HttpJsonPort
andHttpLocalPort
are RPC port numbers (default: 20336, 20337)
-
Seed nodes configuration
- Select at least one seed node out of 4 hosts and fill the seed node address into the
SeelList
of each configuration file. The format isSeed node IP address + Seed node NodePort
.
- Select at least one seed node out of 4 hosts and fill the seed node address into the
-
Create wallet file
- Through command line program, on each host create wallet wallet.dat needed for node implementation.
$ ./ontology account add -d use default value for all options Enter a password for encrypting the private key: Re-enter password: Create account successfully. Address: TA9TVuR4Ynn4VotfpExY5SaEy8a99obFPr Public key: 120202a1cfbe3a0a04183d6c25ceff1e34957ace6e4899e4361c2e1a2bc3c817f90936 Signature scheme: SHA256withECDSA
- Through command line program, on each host create wallet wallet.dat needed for node implementation.
-
Bookkeepers configuration
-
While creating a wallet for each node, the public key information of the wallet will be displayed. Fill in the public key information of all nodes in the
Bookkeepers
field of each node's configuration file.Note: The public key information for each node's wallet can also be viewed via the command line program:
$ ./ontology account list -v * 1 TA9TVuR4Ynn4VotfpExY5SaEy8a99obFPr Signature algorithm: ECDSA Curve: P-256 Key length: 256 bit Public key: 120202a1cfbe3a0a04183d6c25ceff1e34957ace6e4899e4361c2e1a2bc3c817f90936 bit Signature scheme: SHA256withECDSA
Now multi-host configuration is completed, directory structure of each node is as follows:
$ ls config.json ontology wallet.dat
-
A configuration file fragment can refer to the config-dbft.json file in the root directory.
Run each node program in any order and enter the node's wallet password after the Password:
prompt appears.
$ ./ontology
$ - Input your wallet password
Run ./ontology --help
for details.
contract:contract address; - from: transfer from; - to: transfer to; - value: amount;
./ontology asset transfer --caddr=ff00000000000000000000000000000000000001 --value=500 --from TA6nAAdX77wcsAnuBQxG61zXg3vJUAPpgk --to TA6Hsjww86b9KBbXFyKEayMcVVafoTGH4K --password=xxx
If transfer asset successd, the result will show as follow:
[
{
"ContractAddress": "ff00000000000000000000000000000000000001",
"TxHash": "e0ba3d5807289eac243faceb1a2ac63e8dee4eba208ceac193b0bd606861b729",

}

Please open a pull request with a signed commit. We appreciate your help! You can also send your code as emails 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.
