Super Ledger 01--Environment building

About Super Ledger

December 2015, led by the Linux Foundation, IBM, Intel, Cisco and so on jointly announced the establishment of Hyperledger joint project.

Super Ledger project provides open source reference implementation for transparent, open and decentralized enterprise-class distributed ledger technology

The current super ledger community already has

• Aiyisai, Onchain, near-win, Bitse, Boobie, 31 Heavy Industries, Wanda, Huawei and many other domestic enterprises to join

The super Ledger is the first to introduce blockchain technology into the distributed federated Ledger application scenario, laying the groundwork for future efficient business networks based on blockchain technology.

The super Ledger is comprised of eight top-level sub-projects for different purposes and scenarios:

• Fabric: The target is the foundation core platform of the blockchain, support the new consensus mechanism such as PBFT (Byzantine Fault tolerant algorithm), support the Rights management

• Sawtooth: is the blockchain platform that Intel is primarily initiating and contributing. Support for a new hardware-based consensus mechanism proof of Elapsed time (poet)

• Iroha: Ledger platform project, based on C + + implementation, with Web and mobile-oriented features

• Blockchain Explorer: provides a web interface to view the status of the query-bound blockchain (number of chunks, transaction history), etc.

• Cello: provides the deployment and runtime management capabilities of the blockchain platform, and application developers don't care how to build and maintain blockchain

• Indy: A digital identity management mechanism based on distributed ledger technology

• Composer: provides high-level language support for chain code development, automatic generation of chain codes, etc.

• Burrow: provides support for Ethereum virtual machines with a privileged blockchain platform that enables efficient trading

Fabric is the first top project to join the Super Ledger project, the distributed ledger platform for enterprise, the introduction of rights management, support pluggable, extensible, by IBM, DIH and other enterprises submitted to the community at the end of 2015, is the first open-source project for the Alliance chain scenario

Fabric based on Go language, published 1.1.0 version

Hyperledger Fabric Samples Download installation

Create an empty directory

$ mkdir hyfa$ cd hyfa

Download method One:

New File bootstrap.sh

$ vim bootstrap.sh

https://github.com/hyperledger/fabric/blob/master/scripts/bootstrap.shSave the content copy in the exit

Give bootstrap.sh executable permissions and run

$ chmod +x bootstrap.sh

Configuring the Docker Accelerator

The purpose of configuring the Docker accelerator is to speed up the download of the Docker image file

$ curl -sSL https://get.daocloud.io/daotools/set_mirror.sh | sh -s http://8890cb8b.m.daocloud.io

Restarting the Docker service

$ sudo systemctl restart docker.service

Performbootstrap.sh

Determine the network stability, otherwise it will cause a variety of problems, such as downloading to half the network timeout, download failure and so on

$ sudo ./bootstrap.sh 1.1.0

Once the download is complete, review the relevant output and execute the command again if you download a failed image $ sudo ./bootstrap.sh 1.1.0

Download Method Two:

Recommended use mode one for download

Configure the Docker accelerator,

$ curl -sSL https://get.daocloud.io/daotools/set_mirror.sh | sh -s http://8890cb8b.m.daocloud.io

Restarting the Docker service

$ sudo systemctl restart docker.service$ curl  https://github.com/hyperledger/fabric/blob/master/scripts/bootstrap.sh | bash -s 1.1.0

After the installation is complete, output:

Add an environment variable (optional)

The corresponding relative path can be used later

$ export PATH=<path to download location>/bin:$PATH

Note: <path to download location> indicates the fabric-samples path where the downloaded file directory is located

例:  $ export PATH=$HOME/hyfa/fabric-samples/bin:$PATH
