I think you’re exactly right to be thinking of writes and reads separately, with writes being scattered and potentially in various formats. The heavy lifting is deciding what to do with the data, and we can be flexible in our approach: no need for everyone to use the same algo, or even to know what algos are available when creating the trust attestation.

On the topic of zaps: I think it is important to separate out in our minds the notion of PROXY INDICATORS of trust, like zaps, likes, etc, and EXPLICIT CONTEXT BASED TRUST ATTESTATIONS. No reason we can’t use both at the same time! The former exist in spades; it’s time for us to focus our attention on ways to represent the latter.
