Blog
This article details a secure method for generating Ethereum validator keys using a serverless architecture on AWS, addressing key security challenges in blockchain key management.
- Uses AWS Lambda to generate validator keys with high security
- Leverages AWS Key Management Service (KMS) to encrypt keys
- Implements a code signing process with AWS Signer to ensure code integrity
- Stores encrypted validator keys in Amazon DynamoDB
- Provides a secure workflow involving a developer and release manager
The solution ensures that private keys are never exposed, uses isolated Lambda execution environments, and supports secure key generation for Ethereum validators with minimal infrastructure costs.
