Hypechain

Hyperchain is a foundation consortium blockchain platform that meets the needs of industrial applications. Hyperchain integrates high-performance and reliable consensus algorithm and is compatible with the open source community's smart contract development language and execution environment.

Hyperchain provides a high-quality platform for underlying blockchain support and a convenient and reliable all-in-one solution for decentralized applications such as digital asset clearing, trusted data deposit, de-intermediation trade and so on that address the needs of enterprises and industry alliances.

Key Features of Hyperchain

Consensus on block coherence based on RBFT(Robust Byzantine Fault Tolerance)
Limit the entry of blockchain node base on certificate authority
Multilevel Encryption Mechanism Based on Cryptography
Partition consensus based on Namespace
Multi-language support smart contract execution engine HyperVM
- Solidity
- Java
Blockchain data management
- Data visualization
- Data archive
- Smart contract life cycle management

Architecture

The above diagram is a high-level overview of the system architecture used by Hyperchain.

Find more detail in the english documentation and chinese version.

Quick Start

Building from Source

Create Your Clone Clone the repository to a directory of your GOPATH source path:

mkdir -p $GOPATH/src/github.com/hyperchain
cd $GOPATH/src/github.com/hyperchain
git clone https://github.com/hyperchain/hyperchain

Building Please make sure you've installed Go tool properly, if you don't have it already, please see Instructions.

To build Hyperchain:

cd $GOPATH/src/github.com/hyperchain/hyperchain
govendor build

You can run go build as well.

Start up Hyperchain

Since a Hyperchain cluster needs at least 4 nodes to establish a BFT system, we recommend starting up Hyperchain nodes in these modes:

Local Mode - Local 4 Nodes
Distributed Mode - Distributed 4 Nodes

Local Mode - Local 4 Nodes

We've provided a script named local.sh which starts all Hyperchain nodes locally.

cd $GOPATH/src/github.com/hyperchain/hyperchain/scripts
./local.sh

You'll see these information if all Hyperchain nodes start up properly.

$./local.sh
...
...
start up node 1 ... done
start up node 2 ... done
start up node 3 ... done
start up node 4 ... done

Distributed Mode - Distribute 4 Nodes

Enable Password Less Since server.sh script prompts for a password when executing ssh operations, we recommend generating SSH keys on the deploy node and distribute the public key to each Hyperchain node.

1 . Generate the SSH keys, and leave the passphrase empty:

ssh-keygen

Generating public/private key pair.
Enter file in which to save the key (/home/hyperchain/.ssh/id_rsa):
Enter passphrase (empty for no passphrase):
Enter same passphrase again:
Your identification has been saved in /home/hyperchain/.ssh/id_rsa.
Your public key has been saved in /home/hyperchain/.ssh/id_rsa.pub.

2 . Copy the key to each Hyperchain node, replacing {username} with the user name you created.

ssh-copy-id {username}@node1
ssh-copy-id {username}@node2
ssh-copy-id {username}@node3
ssh-copy-id {username}@node4

Distribute Hyperchain We've provided a script named server.sh which distributes Hyperchain to all nodes and starts up them separately.

1 . Put servers' IP addresses into a file named serverlist.txt which under hyperchain/scripts directory.

For instance:

cat $GOPATH/src/github.com/hyperchain/hyperchain/scripts/serverlist.txt
172.16.1.101
172.16.1.102
172.16.1.103
172.16.1.104

2 . Start up Hyperchain with server.sh script.

cd $GOPATH/src/github.com/hyperchain/hyperchain/scripts
./server.sh

You'll see these information if all Hyperchain nodes start up properly.

$./server.sh
...
...
start up node 1 ... done
start up node 2 ... done
start up node 3 ... done
start up node 4 ... done

Documentation

We used readTheDoc to manage our project documentation, which contains the system architecture design, the introduction of key modules, system configuration, user manuals, project developement roadmap and other details.
