A method performed at an electronic device with one or more processors and memory includes obtaining a public record including a plurality of commit nodes, where a respective commit node of the plurality of commit nodes includes: (i) a set of blobs corresponding to a collection of data; (ii) at least one cryptographic hash of one of the set of blobs; and (iii) at least one additional cryptographic hash of a parent node. The method includes: caching the public record; and obtaining, at a time after the obtaining, information corresponding to a new commit node, where the new commit node: includes a cryptographic hash of a parent node; and is associated with an updated collection of data. The method includes validating the new commit node; and in accordance with a determination that the new commit node is valid, updates the cached public record to include the new commit node.
