Automating Hyperledger Fabric chaincode deployment on Amazon Managed Blockchain using AWS CodePipeline
Amazon Managed Blockchain is a fully managed service that makes it easy to create and manage blockchain networks using the open-source blockchain framework Hyperledger Fabric. In this post, we explore how to use AWS CodePipeline and related services to automate the deployment of chaincode. Chaincode is a program that typically handles business logic agreed to […]Read More
This post discusses how these telecommunication companies used Amazon Managed Blockchain to build a universal mobile identity card platform and how this service works.Read More
In the first post of this series, you learned how to build a Hyperledger Fabric network using Amazon Managed Blockchain. In this post, you deploy and run Hyperledger Explorer to visualize the Fabric network that you created.Read More
Managed Blockchain follows an event-driven architecture. We can open up a wide range of analytic approaches by streaming events to Amazon Kinesis. For instance, we could analyze events in near-real time with Kinesis Data Analytics, perform petabyte scale data warehousing with Amazon RedShift, or use the Hadoop ecosystem with Amazon EMR. This allows us to use the right approach for every blockchain analytics use case.
In this post, we show you one approach that uses Amazon Kinesis Data Firehose to capture, monitor, and aggregate events into a dataset, and analyze it with Amazon Athena using standard SQL.
This post demonstrates how to set up a blockchain application written in Java to read and write data to Managed Blockchain using the Fabric Java SDK. The Java SDK allows customers with applications written in Java to integrate blockchain support with their existing codebase. This makes it easier to handle rich data structures and complex business logic before writing records to the blockchain. You can also integrate Managed Blockchain using the Fabric Node.js SDK. For more information, see Building serverless blockchain application with Fabric Node.js SDK.Read More
Accessing Amazon Managed Blockchain services from blockchain applications running in shared Amazon VPCs
Many AWS customers use AWS Organizations and shared virtual private clouds (VPCs) to reduce operational costs and optimize the use of shared resources. For example, shared VPCs allow you to segregate ownership between systems management and application development teams. For more information, see VPC sharing: A new approach to multiple accounts and VPC management. Using […]Read More
This is a guest post from Sammy Jordan, Assistant Treasurer at Contura Energy, in partnership with Emile Baizel, Sr. Blockchain Architect at AWS. In their own words, “Contura Energy is a Tennessee-based coal supplier with affiliate mining operations across major coal basins in Virginia, West Virginia, and Pennsylvania. We export metallurgical coal, a key raw material in steelmaking, to customers on five continents and approximately 25 countries.” Contura chose to run the blockchain network on Amazon Managed Blockchain because it’s a fully managed service that scales automatically, as needed, and removes a lot of the heavy lifting needed to operate a blockchain network. Additionally, you can easily integrate Managed Blockchain with other AWS services, and Managed Blockchain simplifies growing and administering the blockchain network. Network governance and inviting new members can be done via the AWS Management Console, and each member is billed separately based on their own usage.Read More
Applications built on Amazon Managed Blockchain allow multiple parties to transact with one another in a trusted environment with the ability for each party to endorse transactions before they are committed to the blockchain. Blockchain events allow applications to respond to activity and updates to the smart contracts that have been deployed to the network, […]Read More
AWS recently launched a new integration between Amazon Managed Blockchain and Amazon CloudWatch. You can now benefit from detailed logs showing important activity in your blockchain networks, including activity in your member certificate authority (CA), Hyperledger Fabric peer nodes, and chaincode. This post shows how to use these new features to track blockchain activity in […]Read More
Amazon Managed Blockchain makes it easy to create and manage scalable blockchain networks. In Part 1 of this multi-part post, you learned how to deploy a Hyperledger Fabric blockchain using Amazon Managed Blockchain. You also learned how to deploy a REST API to provide a simple interface to read and write to the network. To […]Read More
