Use Key Management Service (AWS KMS) to securely manage Ethereum accounts: Part 1

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 […]

Deploy an Ethereum node on Amazon Managed Blockchain

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 […]

Integrate Amazon Managed Blockchain identities with Amazon Cognito

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 […]

AerLink is digitally transforming the aircraft leasing and financing industry using Amazon Managed Blockchain

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 […]

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 […]

Keeping data private with private data collections on Amazon Managed Blockchain

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 […]

Performing analytics on Amazon Managed Blockchain

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.

Building a blockchain application in Java using Amazon Managed Blockchain

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.
