Ontology_Zero is a decentralized distributed network protocol based on blockchain technology and developed base on DNA(Distributed Networks Architecture). Through peer-to-peer network, Ontology_Zero can be used to digitize assets and provide financial service, including asset registration, issuance, transfer, etc.
- Scalable Lightweight Universal Smart Contract
- Crosschain Interactive Protocol
- Quantum-Resistant Cryptography (optional module)
- China National Crypto Standard (optional module)
- High Optimization of TPS
- Distributed Storage and File Sharding Solutions Based on IPFS
- P2P Link Layer Encryption
- Node Access Control
- Multiple Consensus Algorithm Support (DBFT/RBFT/SBFT)
- Configurable Block Generation Time
- Configurable Digital Currency Incentive
- Configable Sharding Consensus (in progress)
The requirements to build Ontology_Zero are:
- Go version 1.8 or later
- Glide (a third-party package management tool)
- Properly configured Go environment
Clone the Ontology_Zero repository into the appropriate $GOPATH/src directory.
$ git clone https://github.com/dappledger/Ontology_Zero.git
Fetch the dependent third-party packages with glide.
$ cd Ontology_Zero
$ glide install
Build the source code with make.
$ make
After building the source code, you should see two executable programs:
node
: the node programnodectl
: command line tool for node control
Follow the procedures in Deployment section to give them a shot!
To run Ontology_Zero successfully, at least 4 nodes are required. The four nodes can be deployed in the following two way:
- multi-hosts deployment
- single-host deployment
We can do a quick multi-host deployment by modifying the default configuration file config.json
. Change the IP address in SeedList
section to the seed node's IP address, and then copy the changed file to the hosts that you will run on.
On each host, put the executable program node
, nodectl
and the configuration file config.json
into the same directory. Like :
$ ls
config.json node nodectl
Each node also needs a wallet.dat
to run. The quickest way to generate wallets is to run ./nodectl wallet -c -p YourPassword
on each host.
Then, change the BookKeepers
field to the 4 nodes' wallet public keys, which you can get from the last command's echo. The public key sequence does not matter.
Now all configurations are completed.
Here's an snippet for configuration, note that 10.0.1.100
and 10.0.1.101
are public seed node's addresses:
$ cat config.json
"SeedList": [
"10.0.1.100:10338",
"10.0.1.101:10338",
"10.0.1.102:10338"
],
"BookKeepers": [

"NodePort": 10338,
...
Copy the executable file node
, nodectl
and configuration file config.json
to 4 different directories on the single host. Then change each config.json
file as following.
- The SeedList section should be same in all
config.json
. - For the seed node, the
NodePort
is the same with the port inSeedList
part. - For each non-seed node, the
NodePort
should have different ports. - Also make sure that the
HttpJsonPort
andHttpLocalPort
of each node do not conflict with those of the current host. After changing the configuration file, we also need to generate a wallet for each node and field theBookKeepers
with the 4 nodes' wallet public keys. Please follow the steps in the multi-hosts deployment section above. Here's an example:

Start the seed node program first and then other nodes. Just run:
$ ./node
$ - input you wallet password
We also provide an open testing environment. It supports the operation below:
- make some transactions :
./nodectl --ip 139.219.65.178 --port 10336 test -tx perf -num 10
- register, issue, transfer assert :
./nodectl --ip 139.219.65.178 --port 10336 test -tx full
- look up block's information :
./nodectl --ip 139.219.65.178 --port 10336 info -height 10
- look up transaction's information :
./nodectl --ip 139.219.65.178 --port 10336 info -txhash d438896f07786b74281bc70259b0caaccb87460171104ea17473b5e802033a98
......
Run ./nodectl --h
for more details.
Some other available nodes for testing:
IP PORT
----------------------
139.219.65.178: 10336
139.219.99.201: 10336
139.219.96.154: 10336
Notice: The nodes above are intended to be used for public testing only. The data saved on the testing chain maybe be reset at any time. Keep in mind to back up the data by yourself to avoid data loss.
Can I contribute patches to Ontology_Zero project?
Yes! Please open a pull request with signed-off commits. We appreciate your help!
You can also send your patches as emails to the developer mailing list. Please join the Ontology_Zero mailing list or forum and talk to us about it.
Either way, if you don't sign off your patches, we will not accept them. This means adding a line that says "Signed-off-by: Name " at the end of each commit, indicating that you wrote the code and have the right to pass it on as an open source patch.
Also, please write good git commit messages. A good commit message looks like this:
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 etc.
The body of the commit message can be several paragraphs, and
please do proper word-wrap and keep columns shorter than about
74 characters or so. That way "git log" will show things
nicely even when it's indented.
Make sure you explain your solution and why you're doing what you're
doing, as opposed to describing what you're doing. Reviewers and your
future self can read the patch, but might not understand why a
particular solution was implemented.
