One of the challenges of deploying a Cosmos-based application specific chain is the complexity around securing the chain. Each application chain requires gathering validators, distributing staking tokens and designing a token mechanism that helps secure the chain. Saga uses shared security to remove this barrier to entry. Every Saga Chainlet is secured by the Saga Mainnet validators using shared security.
There are many flavors of shared security. Saga uses a model similar to the Cosmos Hub’s version 1 interchain staking called Optimistic Coordination to ensure security of each of the Chainlets.
Every validator on the Saga Mainnet is required to validate every Chainlet provisioned
Validators agree on a set of SLA for Chainlet provisioning and maintenance such as timely deployments, guaranteed compute capacity, minimum uptime, honest consensus participation, and inter-blockchain communication relaying
An auditor monitors the Chainlet and creates a governance case in the event that a validator fails to meet service obligations
Saga Mainnet enforces any consequences needed for validators violating SLA
With Optimistic Coordination, Chainlets automatically inherit the security of the Saga Mainnet. However, to make provisioning Chainlets as simple as possible, Saga requires a suite of tools to facilitate Chainlet orchestration for validators.
