@ping_pub In short, changing the way the Lagrange coefficients are computed does not necessarily produces the stake-weighted threshold property. One still needs t out of n shares, independently of associated stakes.

[Daniel Cason @dcason_bft]

@ping_pub Hey, interesting article. But the transformation from a ordinary t-of-n threshold signing to a stake-weighted threshold signing in section 3.4 is a bit complex. Can you provide more details?

@bugarela Ehe, Twitter is a clear example of a system that sacrifices consistency (order and integrity - read consensus) for performance.

WLAN-enabled multicast primitives, not only for high-level routing purposes, would change dramatically how blockchain systems perform at scale.

[DoubleZero @doublezero]

Multicast Monday.

Multicast is one of the most important performance unlocks in distributed systems and also one of the least understood.

Let’s fix that ↓

@arc testnet has been live for months, offering programmable finance with stablecoin native gas and sub-second finality

• join dc: https://t.co/t0ObH8f9Fa
• engage with the team and other builders
• build useful finance products

@_patrickogrady @commonwarexyz @B_Chou @vex_0x But are you paying an extra communication delay in this case, aren't you?

A real problem for all systems secured by cryptographic primitives, in particular blockchains. The question is not if quantum computing can break existing crypto, the question is when it will.

[Circle @circle]

How will blockchains adapt to quantum computing?

Circle Research explains how the industry is preparing for Q-Day.

[Arc @arc]

Live this Friday at 11 AM ET on 𝕏.

Principal Product Manager @AdiSeredinschi and @corey__cooper will walk through the reliability work behind the latest Technical Insights blog and break down how Arc achieves predictable performance and consistent block times.

We’ll cover:
→ How the team tested Reth and the Malachite consensus engine
→ The tools used to push Arc to its limits: Quake, Guzzler, and Spammer
→ How Arc delivers stable ~500ms block cadence across validators

Deep dive. Engineering tradeoffs. Transparent look into how Arc is built.

[Daniel Cason @dcason_bft]

End-to-end test infra (quake) and load generation tools to spawn realistic network topologies and push the protocol to its limits. Way to go!

[Arc @arc]

Arc is designed as the Economic OS for the internet and reliability is at the center of that vision.

Behind the scenes, our teams pushed Arc to its limits before opening testnet:

→ Chaos-testing entire networks with Quake
→ Saturating block gas with Guzzler
→ Stress-testing throughput with Spammer

The goal: make Arc settle flows with predictability that institutions can trust, at speeds that builders can rely on.

Every block targets 500ms, finalizing with regularity across a globally distributed validator set.

And we’re just getting started.

As we march toward mainnet in 2026, Arc is evolving toward four-nines uptime capability and seamless upgradeability for a settlement layer where you can build and coordinate real-world economic activity.

Explore the latest from Circle Research: Time is Money

This paper develops a new model to evaluate how the speed and cost of crosschain capital allocation affects capital efficiency and profitability.

Capital efficiency is everything for solvers, but unpredictable markets and slow crosschain transfers often trap funds in underperforming places.

We’ve applied this model to Circle Gateway, showcasing how instantly dispensing USDC crosschain provides an optimal allocation strategy, increasing capital efficiency and profit for solvers like @Rockaway_X.
