Specifying oracle mechanism

• Forum post published with requirements for the Logos Oracle Network (LON) and first design iterations

• Review first iteration and explore offchain aggregation with single oracle (type 0)
• First proof-of-concept implementations

Integrate and dogfood capability discovery in Logos Delivery

• Dogfooding of the latest round of fixes completed with no new issues found

• Organise a synchronous dogfooding session using chat2disco

• Waiting for nim-libp2p and Logos Delivery to release new versions

Specify and implement extended DoS and exit node abuse protection

• PR review comments addressed and stake-weighted Mix RLN DoS protection spec refactored
• RLN proof encryption update and implementation in progress (WIP)

• Complete RLN proof encryption
• Update Mix RLN Spam Protection Plugin to reflect the spec refactor

Integrate de-MLS into Logos Chat

• Architecture reworked from client-centric to conversation-centric
• Consensus library release published with signer trait

• Planning next iteration of integration with Jazz

Implement MVP payment protocol

• FFI and protobuf plumbing implemented for payment channels

• Begin integration with Logos Core

NAT Traversal progress

• DHT client mode merged — key for maintaining content lookup performance when nodes sit behind NATs/firewalls — logos-storage-nim-dht #115
• Working on integrating DHT client mode into Logos Storage Nim
• Began scoping work on wrapping libplum — a modern port mapping library supporting PCP in addition to UPnP and NAT-PMP — in Nim

• NAT tests: "NAT transport" simulates NAT filtering at the libp2p level for limited testing
• Removed (local) public address discovery code from node
• Look at libplum; Arnaud will talk to Jacek to decide whether to land it in nim-nat-traversal or as a separate wrapper

Mix Protocol read-behavior encoding

• Proposed encoding of the so-called destination read behavior in the Sphinx packet payload, so that Mix protocol becomes destination protocol agnostic
• Implemented proof of concept of the above Mix Protocol extension — mix-read-behavior-option-1, mix-read-behavior-option-2
• Currently supporting a new libp2p protocol in Mix requires recompiling and redeploying all exit nodes; this PoC makes protocols encodable instead of hard-coded

• Encoding delivery method in the Mix Protocol payload: drafting spec updates and hardening implementation with tests
• Continue working on the Mix transport layer

Exit-node investigation and DHT proxy experiments

• Investigating how exit nodes work and running first experiments with DHT proxies
• Investigating apparent 3-fold increase in memory usage with Mix enabled
