Introduction Hyperledger Composer is a framework for developing Blockchain Applications on the Hyperledger Fabric Blockchain Platform.

Autenticación Passport-JWT para Hyperledger Composer Rest Server

We recently covered Getting Started with Hyperledger Composer, and I would recommend you go through that article if you are not familiar with the technology. In this article, we will do the following:- Create a sample business network definitionGenerate a Composer Rest Server with Docker and PassportJWT authenticationConsume the Authenticated API using a custom JWT token.

The Blockchain technology is considered without a shadow of doubt, one of the most powerful technological innovations of recent years.

Tim O’Reilly counts this technology among those that he defines ‘That happens gradually, then suddenly’. They slowly, but inexorably, insinuate into our digital life until exploding in an unexpected way and without chance to escape, changing our habits of consumers of services and products. Designed and implemented by the brain of a single person, or a group of people, known on the web under the pseudonym of Satoshi Nakamoto, this technology is conventionally associated with cryptocurrency Thanks to this technology, the transition to the abstraction of money and goods in token (tokenization) will break down intermediaries (banks, lenders, etc) between us and our capital, overcoming the limitations of international ‘currency’. However, digital money is not the only application that is a great ally in the blockchain.

Using the blockchain to create secure backups. Some of the properties we would like to see in our backups have blockchain technology written all over them.

Using the blockchain to create secure backups

Should organizations consider blockchain for creating secure, recent backups—especially after a ransomware attack? “Oh no! Sentinel Trails - Logs, Data, Documents: Protected by Blockchain.

Qu'est-ce que la Blockchain et que peut-elle apporter à la protection de vos données ? - Acronis. Sia. SINOVATE Blockchain dCloud Storage. Data integrity proofs in cloud storage. Proof of Retrievability (POR) - consensus. A proof of Retrievability (POR) is a compact proof by a file system (prover) to a client (verifier) that a target file F is intact, in the sense that the client can fully recover it.

Proof of Retrievability (POR) - consensus

As PORs incur lower communication complexity than transmission of F itself, they are an attractive building block for high-assurance remote storage systems. It can be really useful as a consensus algorithm for Cloud computing systems. Permacoin proposed a modification to Bitcoin that repurposes its mining resources to achieve a more broadly useful goal: distributed storage of archival data.

Management and Monitoring of IoT Devices Using Blockchain <sup>†</sup>. - Abstract

These devices are designed to make life easier and more comfortable. Blockchain technology, especially its mass application, is becoming a term number one. Adoption of blockchain into enterprise networks still has a few challenges that need to be tackled.
