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 […]

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. […]

Recent security incidents across blockchain and broader IT sectors underscore the persistent risk of sophisticated attacks on software supply chains and build environments. Reproducible builds offer a powerful mitigation strategy by making sure that software compiled from the same source code and dependencies consistently produces identical binaries, making it possible to detect tampering. In this […]

Digital assets is a rapidly maturing set of asset class, and customers are choosing AWS to build exchanges and trading platforms to differentiate their offerings across this dynamic and growing industry. In this multi part series, we explore the world of centralized exchange (CEX) and market maker (MM) infrastructure on AWS. In Part 1, we […]

Different types of blockchain applications and users demand varying types of private key management solutions, referred to as wallets. Custodial wallets are managed by third-party vendors such as a centralized crypto exchange, whereas non-custodial wallets give you full control and ownership over your private keys and funds. Crypto-native users with experience managing their own digital […]

Those who choose to take ownership of digital assets, such as cryptocurrency or non-fungible tokens (NFTs), are faced with a crucial decision when creating a wallet: do they opt to manage their own wallet or delegate that responsibility to a trusted third party? Non-custodial wallet solutions, whereby a user manages their own wallet, are popular […]

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 […]

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 […]
