In September 2022, Ethereum transitioned to a Proof of Stake (PoS) consensus model. This change allows anyone with a minimum of 32 ether to stake their holdings and operate a validator node, thereby participating in network validation and earning staking rewards. In this post, we explore the technical challenges and requirements of operating an institutional-grade Ethereum staking service. Additionally, we outline a solution for deploying an Ethereum staking service on AWS.

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. In this post, we focus on multi-party computation (MPC) wallets. We introduce the core concepts of MPC wallets, including the security features they offer that make MPC wallets uniquely well suited for institutional customers. We also detail the most critical aspects of implementing a distributed, highly secure MPC wallet on AWS, including a design for a single MPC cosigner that uses AWS Nitro Enclaves to protect the most sensitive information: the key shards.

In order to build an application that interacts with the Bitcoin blockchain, whether it be a wallet, an Ordinals marketplace, or a BTC exchange, you must be able to reliably access the Bitcoin network. For example, you will need to read critical data from the blockchain that acts as input for properly constructed Bitcoin transactions. […]

In the evolving landscape of blockchain technology, understanding the intricacies of node deployment on AWS is paramount in order to be able to interact with the blockchain. In this post, we provide a comprehensive overview of the role nodes serve in blockchain networks, cover the spectrum of available node types, discuss use cases, and present […]

Building a cryptocurrency wallet requires the operation of a multitude of blockchain-specific components that enable critical functionality for the wallet. This includes but is not limited to provisioning and managing blockchain nodes, developing secure private key management solutions, building performant transaction management modules, and working with complex blockchain data pipelines. These components require complex security […]

In this post, we dive deep into establishing your infrastructure and deploying Polygon blockchain nodes on AWS. We provide recommendations for selecting optimal compute and storage options tailored to various use cases. We discuss the approach to speed up the horizontal scaling of Polygon full nodes on AWS with Amazon Simple Storage Service (Amazon S3) […]
