Builders in the blockchain space are often burdened with the undifferentiated heavy lifting involved in managing a resilient fleet of blockchain node clients to access one or more public blockchains. Configuring, provisioning, and maintaining a multitude of public blockchain nodes can be prohibitively resource intensive, both in infrastructure costs and in the human hours required […]

Today, we are happy to announce the general availability of Amazon Managed Blockchain (AMB) Access and Query. These two services expand AMB’s capabilities to help developers seamlessly interact with public blockchains so they can build scalable applications quickly and securely. AMB Access provides a new serverless offering for non-mining, full blockchain nodes. With AMB Access, […]

In Part 1 of this series, we gave a high-level introduction to an AWS Nitro Enclaves-based Web3Signer blockchain validation and signing service. We explained the purpose of running blockchain validators and also why Nitro Enclaves are well suited to run security sensitive cryptographic workloads. We furthermore covered the high-level application architecture and briefly explained the […]

In this series of posts, we provide prescriptive guidance in secure operation of Ethereum validator keys using AWS Nitro Enclaves for node operators who provide staking pools and staking-as-a-service. In this post (Part 1), we explain why AWS Nitro Enclaves are well suited to run Ethereum validators in a secure fashion and we provide a […]

The new proof-of-stake consensus mechanism on Ethereum blockchain network allows network participants to earn rewards without spending a lot of computational power for playing a part in securing the network. Unlike miners, validators don’t need to spend many CPU cycles to produce new blocks. They stake 32 ETH (the native cryptocurrency on Ethereum) to be […]

In this post, you learn how to deploy a cloud-based development environment with which to build, test, and deploy smart contracts on the public Ethereum Goerli testnet via a dedicated Ethereum full node managed using Amazon Managed Blockchain. You can also use the steps outlined in this post to create a development environment on the […]

In the pharmaceutical industry, the cost of clinical research and clinical trials is extremely high, which results in higher drug prices and insurance expenses. Furthermore, the high costs have resulted in decreased numbers of clinical trials at national research institutes and universities, slowing the progress of pharmaceutical research. In addition, incidents of data falsification or […]

Learn how to automate Avalanche node deployment on AWS using the AWS Cloud Development Kit (CDK). This post walks through the step-by-step process of setting up a blockchain node infrastructure, including creating S3 buckets for certificate backup, configuring KMS encryption, establishing EC2 instances, and implementing proper networking.

A common frustration among people who buy tickets to concerts, plays, and other events is that each ticket carries multiple fees. The fees often vary in ways that seem hard to comprehend, making the final cost unpredictable. Through the ticket’s lifecycle, multiple intermediaries can add to the cost and collect revenue, with no monetary benefit […]
