Release Notes
Run a node
Discussed
-
New in v0.2.1: a multidimensional base-fee market with separate storage and execution markets. Storage fees adjust every five days for pricing stability (LEZ needs predictable inscription costs), execution adjusts per block. Fees split roughly 60/40 between the Blend network reward pool and block proposal leaders, so Blend nodes now earn from transaction fees.
-
v0.2.1 is the release set (like a Linux distro) with individual modules pinned to their own versions. Node operator docs live at docs.logos.co.
-
A proof-of-work bootstrap path called Empowering is coming in v0.3, letting newcomers mine just enough tokens to enter proof of stake, removing the “convince someone to give you your first token” permission barrier. PoW is deliberately unprofitable long term.
-
The initial block download was rebuilt. The old design funneled everything through four bootstrap nodes, causing 24 to 36 hour sync times. The new BitTorrent-style model spreads downloads across the whole network while pinning to trusted peers for the tip, followed by a prolonged bootstrap period to hedge against a malicious trusted peer. Bottleneck is now ZK proof validation, not bandwidth. Side discussion on possibly using Logos Storage’s content distribution for chain data.
-
The service discovery protocol (SDP) is an on-chain membership registry used by Blend, potentially DA later, with possible overlap with the capabilities module.
-
Channel balances are now UTXO-backed. Funds bridged into LEZ previously left the UTXO ledger and couldn’t participate in private proof of stake. Channel balances are now backed by real UTXOs, so bridged funds still secure the L1. Shipped early (was planned for v0.3).
-
Logos Storage’s NAT traversal work is now shared across the stack. The long war story covered routers, hotel Wi-Fi demos, and users giving up at conferences. They modernised libp2p’s NAT machinery (new port mapping library supporting PCP, periodic reachability checks, external IP discovery, relay fallback) and integrated it into the shared p2p layer so all Logos modules benefit.
-
Logos Messaging: improved node API, new store query API, better de-MLS integration in chat, improved app and Basecamp UIs.
-
Decentralised MLS (de-MLS) group encryption: standard MLS’s centralised delivery and authentication services replaced with Logos delivery plus an off-chain group consensus with an untrusted “steward” role. Decentralised MLS is a years-long holy grail of the anonymous comms world. Now also powers direct chats and multi-device.
-
The mix network adds routing anonymity for any libp2p connection: multi-hop routing, random delays, uniform packet sizes, cover traffic, and RLN (rate limiting nullifiers) as pluggable Sybil/DoS protection with staking and slashing. Close collaboration with the storage team toward anonymous downloads in v0.3, with a transport-layer-over-mix design needed for larger transfers and an honest caveat that long sessions degrade anonymity.
-
A unified discovery protocol adapts DiscNG for the Kademlia DHT, enabling capability-specific node discovery (e.g. find nodes running blockchain plus storage) while keeping randomisation for eclipse resistance. In testnet now, modules adopt it from v0.3, delivery first. Privacy-preserving discovery is the next research step.
-
RLN is being packaged as a reusable module for v0.3; Zerokit v3.0.0 released.
-
Decentralised sequencing for LEZ arrives in v0.3. Instead of running a second consensus network like other L2s, sequencer rotation is coordinated on the L1 itself: channels specify a rotation, and the L1 only accepts posts from whoever’s turn it is. Already implemented at L1, LEZ will be the first zone to adopt it.
-
λSQL (v0.3) turns any L1 channel into a decentralised database by intercepting SQLite writes and posting them to the channel as a distributed log, with clients replaying for replication. Your own devices acting as client-level sequencers.
