Modular validation

Validation methods are also modular in OpenLayer’s design. The only principle for all validation methods is that they have to be retroactively, cryptographically provable. And for the same type of proof, multiple different providers could provide the service and it’s up to the developers to choose which provider to use.

For example on attested TLS connection. There could be multiple providers providing notary services, some of them may use TEE to enhance the authenticity of their execution, some of them may use multi-notary solutions or multiple notarizations to enhance secureness, some may combine both approaches. Choosing which provider to use is a decision based on requirement for security, trustlessness and cost.
