Week #10 · 13–19 Jul 2026 · Milestone 1 · Adaptive Sharding · Week 12

Split the work, not the world

CURRENT MILESTONE

Milestone 1 · Adaptive Sharding

Teaching the network to split and merge its shards on its own

Week 12

Previously: flightofthefox expanded formal proofs with Model F covering the full reshape lifecycle, ran adversarial Monte Carlo analysis on validator shuffling, and moved safe-vote and ratification structures to durable

If last week was about proving the reshape math, this week was about making shards survive the worst. flightofthefox built an entire halt-recovery system — the machinery to detect a frozen shard, redraw its committee, and bring it back to life without losing or duplicating a single transaction. It was a big, dense week with 60 commits across nearly every part of the codebase.

What flightofthefox built

Shards that heal themselves

flightofthefox built a full halt-recovery pipeline: detecting stalled shards, re-drawing their entire committee, bridging consensus over a proven parent, and freezing cross-shard transactions until the shard is safe again.

Beacon punishes silence, rewards recency

The beacon now jails validators who withhold randomness proposals, weights committee re-samples by how recently each validator served, and evicts the longest-tenured member each shuffle — keeping the lottery fair and alive.

Randomness by folding, proven by math

Each shard now publishes a per-block randomness reveal that gets folded into the epoch's shared randomness — the seed for committee draws. A new Quint model proves the fold is correct.

The bottom line

Standout change

A complete halt-recovery system now lets a frozen shard be detected, re-staffed, and restored without losing or duplicating cross-shard transactions.

What's next

Likely next: wiring the validator-shuffling logic into production now that halt recovery and the beacon's committee-management are in place.

Heard in the chat

The mood: Community discussion about visibility on X and the radix.wiki site, plus an off-topic drama that got wiped by mods. flightofthefox clarified consensus naming and stressed the value of combining simula

This week's concept

The Will— The dead shard's will

The heart of this week was giving dead shards a clean path back: detecting the stall, freezing cross-shard work, rebuilding the committee, and ensuring straddlers resolve by the fence — not by luck.

Jargon, decoded

Halt recovery — The process of detecting a frozen shard, assigning it a new committee, and bringing it back online without losing transactions.

Randomness reveal — A value each shard publishes every block that gets blended together to create the unpredictable seed for the next committee draw.

Fence freeze — Pausing all cross-shard transactions involving a halted shard until its fate is settled.
