Scorex: A Modular Blockchain, Scala Framework

Scorex is an open-source project written in Scala with loosely coupled and pluggable components. Scorex provides many abstractions for which you have to provide concrete implementations to make the blockchain as per your requirements on the top of Scorex. It is backed by IOHK, a technology company based in Hong Kong.Scorex is still experimental and...

Introduction to Hyperledger Sawtooth

Hyperledger Sawtooth is Hyperledger's open-source blockchain platform, following closely on Hyperledger Fabric. It is an enterprise distributed ledger proposed by Intel and was one of the first projects to join Linux Foundation's Hyperledger umbrella. This platform is modular, scalable, with an innovative consensus model, has unique support for permissioned and permissionless infrastructure and the potential...

Excerpt from What The Heck is BLOCKCHAIN!!

Blockchain has the potential to change the way that the world approaches big data, with enhanced security and data quality. Most of the people know nothing about how Blockchain technology works. For this very reason, I decided to give a gentle introduction to Blockchain technology. Before describing Blockchain First, We will discuss the problem that...

Hyperledger Fabric Certificate Authority(CA) Client

  In the previous blog, we discussed about Fabric CA Architecture, Initializing Fabric-CA Server and Configuring the database. Now, we will discuss how to use fabric-ca-client command. We can interact with Fabric-CA Server via Fabric-CA Client and there can be multiple Fabric-CA Intermediate Servers. Each Intermediate Fabric-CA server can be configured Fabric-CA server cluster. So,...

Config Generator In Hyperledger Fabric

Every Ledger starts with a transaction kept inside the block but what will be the first block? Well, the answer is genesis block. Now, another question how to generate this genesis block? For this part we can use the configtxgen tool to generate the initial or genesis block. The tool is primarily focused on generating...

Crypto Generator in HyperLedger Fabric

Security is the one of the major aspect of any network. Each of the node must have some identity and on the basis of this identity corresponding accesses are granted. The same approach is follow by the Fabric network as well. Fabric CA generates the identity or artifacts file for each of the node that...

Hyperledger Fabric Certificate Authority(CA)

Every operation in Hyperledger must be signed cryptographically with certificates. You can generate certificates yourself using OpenSSL or by using third party. Before moving further into details of CA lets first explore Hyperledger Fabric a little. 😉 Hyperledger Fabric Hyperledger Fabric founded in 2015 which is an umbrella for open source projects some of which...

Microsoft announced Coco Framework for blockchain networks.

On August 10, 2017, Microsoft announced their enterprise-ready blockchain network, Coco Framework. Blockchain technology is now not an unknown technology anymore, with each day passing the number of enterprises supporting and investing in blockchain is increasing.  There are lots of short coming in existing software like latency, performance, governance, etc. Microsoft, one of the tech...

Consensus Algorithms in Blockchain

When we talk about the blockchain, the first thing that came up in our mind is the security and the security because of the blockchain consensus algorithm. Those who know about the blockchain know that we keep the ledger transactions synchronized across the network to ensure that ledgers only update when the appropriate participants approve...
