Blockchain is a hype topic for many years. While many companies talk about the buzzword, it is tough to find use cases where Blockchain is the best solution. The following examples show the potential of Blockchain. Here it might make sense:. Do you need a blockchain? What parts of "blockchain" do you need?
Observability on blockchain and the Hyperledger project
Data processing and visualization of crypto currencies dynamics and technical indicator. In this project we developed a financial data streaming, processing and visualization on crypto currencies. The core of the project is the streaming system Apache Kafka, that allows the blocks to communicate rapidly a great amount of data. At the moment the data processing is limited to the computation of technical indicator like moving average, but in the future it could be implemented some Machine Learning prediction technique with Apache Spark , and a storage for the data like Cassandra. All the implementions could be part of a bigger project of automatic trading. Skip to content. Star 6. Data processing and visualization of crypto currencies dynamics and technical indicator 6 stars 1 fork. This commit does not belong to any branch on this repository, and may belong to a fork outside of the repository.
Web3 is the future, or a scam, or both
Cryptocurrency exchanges like Coinbase, Binance, and Kraken enable investors to buy, sell and trade cryptocurrencies, including Bitcoin, Litecoin, Ethereum and many more. Depending on the exchange, trades can be made using fiat currencies legal government tender like U. Most exchanges also allow investors to purchase one type of cryptocurrency with another for example, buy Bitcoin with Ethereum. Given the high velocity and high volatility of cryptocurrency valuations, monitoring and analyzing trading activity and the performance of trading algorithms is daunting.
[Not completed yet] Implementing a Blockchain using Kafka
When you hear the terms, producer, consumer, topic category, broker, and cluster used together to describe a messaging system, something is brewing in the pipelines. Get connected and learn what that is, and what it means! Many Big Data use cases have one thing in common - the use of Apache Kafka somewhere in the mix. Whether the distributed, partitioned, replicated commit log service is being used for messaging, website activity tracking, stream processing or more, there's no denying it is a hot technology. In this course, you will learn how Kafka is used in the real world and its architecture and components.
EthVM: First Open-Source Block Explorer Powered by Kafka
Try out PMC Labs and tell us what you think. Learn More. Providing security and privacy to the Internet of Things IoT networks while achieving it with minimum performance requirements is an open research challenge. Blockchain technology, as a distributed and decentralized ledger, is a potential solution to tackle the limitations of the current peer-to-peer IoT networks. This paper presents the development of an integrated IoT system implementing the permissioned blockchain Hyperledger Fabric HLF to secure the edge computing devices by employing a local authentication process. In addition, the proposed model provides traceability for the data generated by the IoT devices.
The ABCs of Kafka in Hyperledger Fabric
The REST API Gateway gives application developers everything they need to focus on their app's business logic and user experience, without getting stuck in the complexities of Ethereum transaction submission, thick Web3 client libraries, nonce management, RLP encoding, transaction signing, and smart contract management. Keep track of your deployed smart contracts, with descriptive names and API documentation, rather than strings of Hex addresses. All of the complexities of submitting transactions to Ethereum are handled for you. With one click in the UI you can deploy your first smart contract, then explore that API to send transactions, and read data in a convenient web experience.
Apache Kafka is the most popular open-source stream-processing software for collecting, processing, storing, and analyzing data at scale. Most known for its excellent performance, low latency, fault tolerance, and high throughput, it's capable of handling thousands of messages per second. With over 1, Kafka use cases and counting, some common benefits are building data pipelines, leveraging real-time data streams, enabling operational metrics, and data integration across countless sources. As the trusted tool for empowering and innovating companies, Kafka allows organizations to modernize their data strategies with event streaming architecture. Learn how Kafka is used by organizations in every industry - from computer software, financial services, and health care, to government and transportation.
KafkaBlockchain is a java library for tamper-evidence using Kafka. Messages are optionally encrypted and hashed sequentially. This version has been removed and is no longer available to new customers. The library methods are called within a Kafka application's message producer code to wrap messages, and called within the application's consumer code to unwrap messages. A sample utility program is provided that consumes and verifies a blockchained topic. Because blockchains must be strictly sequentially ordered, Kafka blockchain topics must either have a single partition, or consumers for each partition must cooperate to sequence the records. Sample programs demonstrate blockchains with a single partition and with multiple partitions.
