Private key management remains one of the most challenging security aspects of building Web3 and broader financial applications. In blockchain systems, every transaction requires a cryptographic signature produced by a private key, and whoever possesses those keys controls the associated assets. This means a single compromise can result in immediate, irreversible loss of funds. Traditional […]

Developers building digital asset solutions face a fundamental challenge: connecting traditional cloud infrastructure with blockchain networks while maintaining the security, compliance, and reliability standards that financial institutions require. Today, we’re making it easier to address this challenge with the launch of the Chainlink data standard on AWS Marketplace, with Chainlink Data Feeds, Data Streams, and […]

Part 1 of this series covers the high-level architecture of a Centralized Exchange (CEX) and Market Maker (MM) and networking integration patterns. This post builds on that foundation by focusing on EC2 compute optimization. In this post you will learn how to Reduce tail latency by up to 29% at p99.9 by selecting the right […]

Tokenization, the representation of ownership or claims on real-world assets and securities as digital tokens on distributed ledgers, is modernizing how financial institutions handle settlement and asset transfer. The token itself is not the asset, but a digitally native representation deriving enforceability from legal frameworks, issuance models, and smart contract logic. Tokenization doesn’t replace existing […]

In this post, we show how BSVA used AWS services to build a distributed node architecture that achieves 1 million TPS across six Regions. This solution demonstrates how organizations can implement cloud infrastructure to solve complex blockchain scaling challenges while maintaining system integrity.

This is the English version of the original post published in the AWS Indonesia blog channel. Part 1 of our series introduced key components for running centralized cryptocurrency exchanges (CEX) on AWS. Part 2 (this post) builds upon that knowledge and guides you through migrating CEX workloads to AWS successfully. In the upcoming Part 3 […]

This is the English version of the original post published in the AWS Indonesia blog. Cryptocurrency exchanges are digital marketplaces where users trade various digital currencies like Bitcoin and Ethereum. The exchanges provide a secure environment where millions of people worldwide can participate in the cryptocurrency economy.The cryptocurrency trading landscape features two distinct types of […]

At Circle, we operate scores of nodes across dozens of blockchains in order to provide reliable RPC services supporting products such as USDC, Cross-Chain Transfer Protocol (CCTP), Circle Payments Network (CPN), and others. Circle is a global financial technology firm that enables businesses of all sizes to harness the power of digital currencies and public blockchains for payments, commerce, and financial applications worldwide. In this post, we share details about how we operate Circle’s blockchain node infrastructure at scale, using AWS services, common off-the-shelf tools, and some custom tooling.

In the post Establishing verifiable security: Reproducible builds and AWS Nitro Enclaves, we introduced deterministic and reproducible builds, highlighting their critical role in securing the software supply chain. We also explored how software reproducibility connects to remote attestation, demonstrating how AWS Nitro Enclaves enable decentralized remote verification of runtime and software integrity using cryptographic attestation. […]

In this post, we explain how blockchain-based digital asset payment systems can reduce costs and delays. We demonstrate how to build a serverless payment system on AWS, using stablecoins such as USDC, PYUSD, or USDG as an example. This solution creates a low-cost, scalable, and decentralized alternative to legacy payment methods. The implementation is available in our GitHub repository.
