In this post, we share an open-source solution for running cross-chain analytics on public blockchain data along with public datasets for Bitcoin and Ethereum available through AWS Open Data. These datasets are still experimental and are not recommended for production workloads. You can find the open-source project on GitHub here and the public blockchain datasets […]

Non-fungible tokens (NFTs) have captured global attention as a mechanism for creating one-of-a-kind digital assets that can be instantly verified as authentic, easily exchanged between users, and made infinitely programmable such that NFTs can be used for a variety of use cases and industries. At its core, NFTs are a form of digital asset or […]

In Part 1 of this series, we gave a high-level introduction to the AWS Nitro System and explained why Nitro is well suited for flexible and secure blockchain key management workloads. In Part 2, we guided you through the steps to configure aspects like AWS Key Management Service (AWS KMS) key policies and how to […]

Public blockchains are used for a variety of use cases, like decentralized finance (DeFi) apps, non-fungible token (NFT) apps, or cross-border payments. Blockchains differ in their protocol and consensus design, implementation language, and smart contract capabilities. Determining how external participants can be incentivized to join a network running their own node is key in economic […]

Ownership is one of the core tenets of non-fungible tokens (NFTs)—you can own an NFT and prove that you own it. On blockchain, such a proof of ownership means that the NFT is in a wallet that the owner controls. Only the owner has the private key to that wallet, and only the owner can […]

This is the second post of a two-part series that covers how to store off-chain data using Amazon Managed Blockchain and Amazon Simple Storage Service (Amazon S3). This post builds on the solution setup outlined in Part 1. In Part 1, we presented a solution that implements off-chain storage for non-transactional data using Amazon S3, […]

Companies working in the public sector must often certify that their work complies with required standards and regulations. They must be auditable by external parties and accountable to the general public. Such companies often use a trusted third party that attests to certain attributes of documentation, such as its timestamp or authorship. Blockchains can automate […]

Ethereum is a decentralized, open-source blockchain with smart contract functionality. The Beacon chain (ETH2) is an upgrade to Ethereum that introduced a proof-of-stake concept to the Ethereum ecosystem. Staking in ETH2 is done by validators who perform actions such as attestations and block proposal activities to improve the Ethereum network’s security and scalability. Validators in […]
