Blockchain is a shared, replicated, immutable transaction ledger which is maintained by a distributed network of nodes. The transactions in the ledger are grouped into blocks that include a hash that binds the block to its preceding block, thus creating an immutable chain of blocks. Blockchain networks can be primarily categorized into Permissionless and Permissioned networks. In a Permissionless blockchain, all the participants are anonymous and hence do not have trust in each other. The only source of trust is that the state of the blockchain, prior to a certain depth, is immutable. On the other hand, Permissioned blockchain operates amongst a set of known and identified participants operating under a governance model, which provides a certain degree of trust.
This talk will provide a technical deep dive on Hyperledger Fabric, which is an enterprise grade permissioned distributed ledger framework for developing solutions and applications. Hyperledger Fabric has a highly modular and configurable architecture, enabling innovation, versatility, and optimization for a broad range of industry use cases including banking, finance, insurance, health care, etc. Hyperledger Fabric is the first distributed ledger platform to support smart contracts authored in general-purpose programming languages such as Java, Go, and Node.js, rather than constrained domain-specific languages (DSL). Hyperledger Fabric introduces a new architecture for transactions i.e. execute-order-validate, which addresses the resiliency, flexibility, scalability, performance, and confidentiality challenges faced by the order-execute model. Hyperledger fabric takes a unique approach to consensus which enables performance and scalability while preserving privacy.
