Excellent overview of Sui Move from the @zellic_io team! Also, thanks to Zellic for noticing an odd "ID swap" behavior that ended up being due to a bug in the Sui verifier that we've since fixed.

Ever wondered what's up with Sui, and what the differences between Sui and Aptos are? Check out our new blog post! We introduce Sui, and highlight the differences between Sui, Aptos, and core Move. We also point out a few key security considerations. zellic.io/blog/move-fast…

Move is 6 years old today! Creating a programming language and growing a vibrant developer community is a hard problem that requires long-term commitment. I'm very proud of how far we've come with Move. It's the third largest smart contract language, and the fastest growing SC

Hey @Aptos_Network, I’m disappointed to learn that you pressured @PontemNetwork into removing @TNowacki + @damirka + Shayan Sanjideh as speakers at movecon.live, as well eliminating Sui Foundation from the organizations participating in this community-organized event.

My strongest non-Move view in the crypto space is that The utility of a smart contract platform is proportional to the amount of interesting shared state a program running on that platform can access atomically. I don't think this is particularly deep or controversial.

It's not intellectually honest to claim that the Bybit hack proves the EVM is fundamentally insecure (obviously, EVM, operational, and human factors were involved). However, if asked which policy would have the biggest impact on reducing the frequency and size of crypto hacks, I

BEHIND THE SCENES: Some parties are telling policy makers in DC that the Bybit hack proves the EVM is fundamentally insecure. This is MISINFORMATION. The Bybit hack resulted from Social Engineering and hacking the user interface - NOT a vulnerability in the EVM.

This is the third biggest launch we've ever done: 1. Sui (coordination) 2. Walrus (data) 3. Seal Seal leverages (1) to provide programmable access control for (2) (or any other data source you want to protect via encryption). The Sui stack is starting to feel like a real thing

Seal just launched on Sui Mainnet, and builders are already putting it to work. From token-gated content to confidential AI data, here’s how top teams are using Seal to add programmable privacy and access control to their apps 👇

The best Sui network upgrades just make everything faster, with no work for builders or users (see yellow lines). Awesome work by the consensus team shipping Mysticeti v2.

Sui highlights from EC mid-year dev stats refresh: - Sui is the 2nd fastest growing L1 dev community over the last year at 16.1% -- just a hair behind Solana at 17.7%. - Sui is the fastest growing L1 dev community over the last two years at 54% - This goes against broader growth
