I've been building Confer: private AI chat where your conversations are end-to-end encrypted so that only you can access them. It's still new, but I've been using it every day and beta testing it with friends. Let me know what's missing! https://t.co/EsRRPWWpYj

Another testament to why Sui has one of the best white hat hacking security teams in the world, helping the whole blockchain industry and beyond. Our Chief Hacking Officer @JohnNaulty is a legend, he was part of the research team behind the Milk Sad Vulnerability detection

“2025 will be an explosive year for AI agents on chain” by @JohnNaulty, our BugDar AI and internet-less transactions lead (super smart individual — UC Berkeley alumni, ex-Coinbase, ex-Meta, ex-BitGo, ex NeurotechX / OpenBCI etc etc). Sui launched a Telegram channel dedicated to

Going to Switzerland for 10 days, who's around?

The paper:

The new plotting format builds on new research since Chia was released. It makes on-the-fly plotting 1000x times less practical, while keeping the requirements of normal harvesting (reading random data) nearly as low as today.

A less severe manifestation of the problem is "compressed plots": Farmers run a modified version of Chia that is more space-efficient than the original, but compensates by extra computation (hence uses more energy).

An attacker may rent some GPU capacity to claim a portion of the network incommensurate with the storage capacity they have access to. A violation of the proof-of-space design that can lead to 51% attacks.

Plotting on the fly was very impractical. You must have the data ready in advance. However, since Chia mainnet launched in 2021, the world has started building many more GPUs.

Anyone can become a chia farmer by generating some fresh data (plotting). Plotting is a compute intensive activity meant to be done once when the new storage capacity joins the network.

Proof of space is an alternative to proof of work where miners fill their hard drives with pseudo-random data. When challenged, they must perform a small disk read and submit the data. Most of the time, the mining setup is at rest thus using very little energy - unlike Bitcoin.

Chia announced a 2-year plan to switch to a better model for proof of space. 🧵

@Mysten_Labs @SuiNetwork This may be solvable with a validator committee that rotates every 24 hour cycle.

@Mysten_Labs @SuiNetwork The issue with the approach is that complexity is quadratic with the number of validators. In practice, over 150 validators, the hardware requirements become impratical. Sui has 106 validators today. https://t.co/qKg6UwDmmt

@Mysten_Labs @SuiNetwork This allows high throughput (200k tps) and low latency to coexist within a single network. A different approach than the rollup-centric model embraced by Ethereum, Tezos etc.

@Mysten_Labs @SuiNetwork All in all, Mysticeti offers transaction commit with only 3 network round-trips. For validators spread out around the globe, it means sub-second transaction confirmation in most cases.

@Mysten_Labs @SuiNetwork 2. mysticeti builds on top of narwhal+bullshark, the previous algorithm. Using a novel DAG (directed acyclic graph) approach, it offers an ultra-fast path for transactions that need not be ordered (like simple transfers) while still guaranteeing fast ordering when it matters.

@Mysten_Labs @SuiNetwork 1. traditionally, wait for a block to be attested valid before submitting the next one. No such thing in Mysticeti - submit blocks optimistically, decides which one is good later. The algo ensures that one such good block will always exist even in byzantine scenarios.
