Saga is a protocol for automatically provisioning application-specific blockchains in the multiverse. The protocol design fundamentally reimagines developer and end user interactions with blockchains with a view towards scalability, sovereignty and ease of setup. Using shared security, innovations in validator orchestration, and an automated CI/CD deployment pipeline standardized across single-tenant application VMs, Saga makes launching a dedicated blockchain, or chainlet, as easy as deploying a smart contract.
