Ethereum is a popular public blockchain that makes it possible to create unstoppable applications in a permissionless fashion. It’s available to every user that has an Ethereum account. These Ethereum accounts consist of a private and an associated public key. The main challenge as a user participating in a public blockchain such as Ethereum is […]

Amazon Managed Blockchain support for managed Ethereum nodes makes it possible to build your own decentralized applications (dapps) without having to worry about maintaining reliable Ethereum nodes for relaying blockchain transactions or querying the state of blockchain data. The decentralized architecture of the Ethereum network makes it possible to create unstoppable applications that can be […]

When you authenticate with a web or mobile application, you typically do so with a username and password where you’re authenticated against a user database such as Amazon Cognito. You’re expected to secure your password and rotate it periodically or when it has been compromised. When you’re building a user-facing application that is running on […]

This is a guest post from Finn Mulligan and Sanjaya Krishna, co-founders of AerLink Ltd, in partnership with Maggie Hsu, WW GTM Specialist for Amazon Managed Blockchain AerLink is a Seattle-based startup that is focused on transforming the aircraft leasing and financing industry. Aircraft leasing and financing is currently full of manual, time-intensive processes, and […]

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 […]

With the Amazon Managed Blockchain release of Hyperledger Fabric (HLF) version 1.4 support, the private data collections feature is also officially supported. Before HLF 1.2, the channels feature was the primary way to control data privacy amongst a set of members. But channels have significant limitations: Ordering service nodes still have a copy of all […]

This post discusses how these telecommunication companies used Amazon Managed Blockchain to build a universal mobile identity card platform and how this service works.

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.

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.
