Use AWS Nitro Enclaves to build Cubist CubeSigner, a secure and highly reliable key management platform for Ethereum validators and beyond

Validators are the fundamental building blocks of proof-of-stake (PoS) blockchain protocols like Ethereum. They maintain the history of the chain and run the consensus protocol that makes it possible to implement complex decentralized applications—from decentralized finance applications to NFT collectibles. To join the protocol, validators provide assets as collateral, which ensures they behave correctly in […]

Choose the right type of AWS KMS key to encrypt Amazon RDS and Aurora Global Database

Security is a top priority in any organization. Amazon Relational Database Service (Amazon RDS) makes it easy to set up, operate, and scale a relational database in the AWS Cloud. It provides cost-efficient, resizable capacity for an industry-standard relational database and manages common database administration tasks. Amazon Aurora is a fully managed, MySQL- and PostgreSQL-compatible […]

Optimize AWS KMS decryption costs for Database Activity Streams

In regulated industries like healthcare and finance, auditing database activity is a top priority. Companies need to record the actions performed by database users and administrators to maintain compliance and security. AWS offers robust auditing for databases through Database Activity Streams (DAS). Integrated with Amazon Relational Database Service (Amazon RDS) and Amazon Aurora, DAS produces […]

Make EOA private keys compatible with AWS KMS

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 […]

Import Ethereum private keys to AWS KMS

In the world of digital assets, private keys have always been of utmost importance. Unlike traditional assets, digital assets are controlled by private keys (a string of letters and numbers), just like passwords, which unlock the right to manage and use assets. Private keys can be used to irreversibly transfer funds from the wallet, thus, […]

Securely generate Ethereum validator keys at low cost using a serverless architecture on AWS

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 […]

AWS Nitro Enclaves for secure blockchain key management: Part 1

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 […]

How to sign Ethereum EIP-1559 transactions using AWS KMS

Ethereum is a popular public blockchain that enables you to create decentralized applications across a variety of use cases. In 2020 and 2021, it became widely used for decentralized finance (DeFi) apps and non-fungible token (NFT) apps. Due to its permissionless nature, it’s available to every user by just setting up an Ethereum account. These […]
