-#+TITLE: Encoding for Robust Immutable Storage (ERIS)

-
-* An /encoding/
-
-Defines how to encode arbitrary content into uniformly sized encrypted blocks and how to reassemble them.
-
-Does not define storage level or transport level.
-
-** Inspiration
-
-- Datashards: How to use it for ActivityPub
-- An Encoding for Censorship-Resistant Sharing: implemented in GNUNet filesharing.
-
-** Context
-
-- Work part of the openEngiadina project
-- Supported by NGI0 via the NLNet foundation
-
-** Robustness
-
-- Availability of content
-- Authenticity
-- Plausible deniability for peers
-- Simple to implement correctly
-
-* Overview
-
-[[./images/eris-overview.svg]]
-
-Notable differences to IDSC:
-
-- optional convergence secret
-- verification capability
-
-** Cryptographic primitives
-
-Blake2b & ChaCha20 (IETF variant)
-
-- fast, standardized and widely implemented
-- Blake2b: inbuilt support for keying and personalization (allows implementation of convergence secret and key derivation)
-- ChaCha20: Nonce does not have to have high-entropy (vs. IV of AES)
-
-** Content-addressable storage
-
-- ~cas-put!(block)~
-- ~cas-get(ref)~
-
-Like the "Store Core Interface" in Datashards.
-
-** Read and verification key
-
-- read key :: ~BLAKE2b(content)~, ~BLAKE2b(content, key=covergence-secret)~
-- verification key :: deterministically derived from read key
-
-* Encoding content
-** Split content into uniformly sized blocks

-** Encryption nonce for nodes
-
-- Node position (nonce) can be computed when building the tree from bottom and when decoding from top.
-- Uses fact that ChaCha20 does not require high-entropy nonce
-- Protection against second preimage attack as position of node is encoded into node
-
-** Read capability
-
-[[file:images/eris-merkle-1.svg]]
-
-/Read capability/ consists of: root reference, read key and level of root reference (depth of tree).
-
-** Verification capability
-
-[[file:images/eris-merkle-1.svg]]
-
-/Verification capability/ consists of: root reference, verification key and level of root reference (depth of tree).
-
-* Implementations
-
-- Guile
-- JavaScript (+ ClojureScript bindings)
-- Elixir
-
-Experimental ActivityPub Server and Client (CPub and GeoPub).
-
-* Verification capability
-
-Usefulness of this still needs to be demonstrated...
-
-* Two-pass encoding
-
-1. Compute hash of content
-2. Encode tree
-
-Not suitable for large content!
-
-** Block size
-
-4kB
-
-Small...
-
-*** Maybe smaller
-
-#+BEGIN_QUOTE
-A CoAP message, appropriately encapsulated, SHOULD fit within a single IP packet ... an IP MTU of 1280 bytes SHOULD be assumed.
-
---- The Constrained Application Protocol (CoAP) (RFC 7252)
-#+END_QUOTE
-
-Block size of 1kB?
-
-*** What about large content?
-
-Use ECRS?
-
-(block size 32kb - single pass encoding)
