Sessions fully removed from the Logos Blockchain node: the final feature pull request merged and a fresh devnet deployed logos-blockchain#2850
Smart block building merged: the block builder can now sequence many dependent transactions from the mempool into a single block logos-blockchain#2864
Logos Execution Zone performance benchmarks completed: summary document published covering minimum and recommended hardware requirements for running a zone doc
Four research interns joined the blockchain team for the summer, and two new contributors joined the Logos Execution Zone team

“Modelling of Network Delays” extended with pairwise broadcast latency analysis on random regular graphs: the right tail of the latency distribution decreases with connectivity C and increases with 1/(dλ) doc
“Total Stake Inference with Network Delays” significantly revised: Section 4 reworked, figures regenerated, notation simplified — near complete doc
blockchain:bedrock:research:cryptarchia
Checkpoint-based Fast Bootstrapping RFC revised RFC; “Checkpoint State and StateRoot Specification” subpage substantially extended: new StateRoot specification, checkpoint_state defined as the state after epoch transition and before first block execution, hashing and verification against epoch_state_root, canonical ordering and encoding rules draft
blockchain:bedrock:research:post-quantum
“Post-Quantum Safety Analysis of the Logos Bedrock Layer” document updated doc
“Post-Quantum Migration Strategy for the Logos Bedrock Layer” document started (WIP) doc

Session removal completed: the final feature pull request merged, removing sessions across the stack including SDP and SRP logos-blockchain#2850; leftover session mentions removed #2847; self-applying blocks before broadcasting re-enabled #2851
/blend/join HTTP endpoint added for joining Blend as a core node with an SDP declaration #2873
Stake-less service provision prevention (in-review) #2855; SDP test improvements (in-review) #2852
blockchain:bedrock:eng:mempool
Smart block building merged: the block builder now loops to sequence dependent transactions from the mempool into a single block logos-blockchain#2864, respecting transaction topological order under the block size limit #2868 (supersedes the TxTracker approach #2746)
Wallet tracking from the block feed added to the testing framework logos-blockchain#2835
Local inscription throughput measurements mostly matched theoretical limits: larger payloads bounded by block size, small payloads by per-block transaction count
Proposed-block transaction selection now capped correctly by block size #2842
E2e log-level overrides preserved #2845; node binary set explicitly for nextest e2e runs #2862
E2e test artifact handling improvements merged #2819
Cucumber stress tests improved while stress-testing the new mempool (in-review) #2854
Testing disabled on Nix due to failures in Nix’s restricted environment #2848
blockchain:bedrock:eng:node
Node 0.1.3-rc.8 released with deployment fixes logos-blockchain#2877; manual dispatch added for the Node Docker Image workflow #2865; logging level configurable via the compose run file #2860
Keystore management commands added (generating and adding the devnet faucet key) #2846
Genesis generation binary now checks validity of generated deployment settings #2859; node fails fast on invalid serialized deployment and user configs #2863
CLI init, update and migrate commands reworked: updated keystore file format and commands to generate user_config.yaml from the keystore #2801, with devnet init node keys and recreation instructions documented doc; cargo-hack CI step fixed #2807
blockchain:bedrock:eng:circuits
rust-rapidsnark fork introduced to replace the prover and verifier binaries with library counterparts logos-blockchain#2839; rapidsnark dependency update to address concurrency issues and a buffer-based prover (WIP) branch, branch
Fr field type localised to avoid collisions with other libraries logos-blockchain-circuits#45; circuit file embeds gated behind feature flags (in-review) #44
Generic transaction flows in the wallet FFI finalized (in-review) logos-execution-zone#491; program deployment transactions in the FFI started (WIP) #510
Wallet UI improvements — network selector (testnet/localhost), shielded and deshielded transfers, account filtering by transaction type, syncing progress bar, proof-generation spinner — tested on local and testnet (in-review) logos-execution-zone-wallet-ui#16
Wallet UI journey draft targeting current v0.1.2 functionality doc
