What if you could resolve a content digest (e.g. a SHA-256) to its location anywhere on the internet, just like DNS resolves a domain name to an IP address? This talk introduces ent, a simple protocol for distributed Content-Addressable Storage (CAS) that does exactly that, preserving integrity and verifiability of the underlying data even when servers are untrusted.
A common pattern that arises in many systems (and especially in anything related to transparency) is that of mutable pointers (e.g. labels, tags, keys, package names, version numbers, etc.) referencing immutable data. We explore how ent provides a flexible, scalable, and secure resolution layer for any CAS, decoupling data’s identity from its location.
The presentation will cover the protocol, our open-source client and server libraries, a few use cases, and a demonstration of static.space, a public ent server you can use today.
