00The Sui Stack: Building A Future Where We Don’t Have to Trust, We Can Verify
Sui’s recent post featuring Evan Cheng, Co-Founder & CEO of Mysten Labs, is more than just another project update—it’s a deliberate reveal of how far the Sui Stack has matured and how it’s setting the standard for Layer 1 blockchain infrastructure. What Evan articulates in the video is a clear expression of what many of us building in crypto already understand: that performance, scalability, and developer accessibility aren’t just features they’re requirements for real world blockchain adoption. And Sui has built those into its core from the ground up. The Sui Stack stands out because it solves foundational pain points. Move, the language powering Sui, isn’t just secure it’s asset-native. This changes the game for tokenization, identity, and ownership. Every asset on Sui is treated as a first-class citizen, making composability, modularity, and verifiability more intuitive and robust. From an architectural standpoint, Sui introduces a powerful data model that avoids the bottlenecks of account-based chains. Objects are separate from accounts, meaning parallel execution can happen at scale, without compromising security or decentralization. This unlocks true horizontal scaling a crucial advantage when you’re talking about global, user-facing applications like games, social networks, and digital commerce. What I appreciate most about this update is how Mysten Labs continues to push for transparency. This isn’t just a roadmap or a PR stunt it’s a builder focused breakdown of where the tech is and where it’s headed. For developers, you get a framework built around object-centric programming. For enterprise and protocol teams, you get predictable throughput, finality under 2 seconds, and lower gas volatility this makes designing user first experiences on-chain much more viable. The video underscores why Sui is leading in innovation: zkLogin integration, verifiable off-chain computation, dynamic fields, and programmable transaction blocks these aren’t surface level features. They’re part of a long-term vision for chain utility and flexibility. And with Mysten Labs’ background in systems engineering and their involvement in Diem (formerly Libra), you know this vision is backed by some of the sharpest minds in blockchain R\&D. If you’re serious about building in Web3 whether infrastructure, consumer apps, or modular tooling, Sui gives you a complete foundation to build with purpose, scale with confidence, and deploy with clarity. I’ve followed Sui’s evolution from testnet to mainnet, and this update validates what many of us have known for a while: this chain isn’t just ready it’s redefining what readiness looks like in blockchain. Let’s keep the conversation going check https://x.com/SuiNetwork/status/1945910251720720794 for more. what parts of the Sui Stack are you most excited to build with next?

PourThe GraphMar 14, 2025GRT Token - qu'en pensez-vous ?
The Graph (GRT) est un protocole décentralisé conçu pour indexer et interroger les données des blockchains, à commencer par Ethereum. Il permet aux développeurs de créer et de publier des API ouvertes, appelées sous-graphes, qui rendent les données de la blockchain facilement accessibles pour les applications décentralisées (DApps). Le jeton natif, GRT, est utilisé au sein du réseau par des participants tels que les indexeurs, les curateurs et les délégués afin de garantir la sécurité économique et l'intégrité des données interrogées. Au 14 mars 2025, GRT se négociait à environ 0,094$, avec un volume de transactions sur 24 heures d'environ 36 millions de dollars. Ce prix actuel reflète une baisse significative par rapport à son sommet historique de 2,84$, indiquant une tendance à la baisse au cours des dernières années. La trajectoire des prix du GRT a été influencée par divers facteurs, notamment les avancées technologiques, l'évolution de la réglementation et des indicateurs macroéconomiques plus généraux. Ces éléments ont collectivement contribué à la baisse de valeur observée au fil du temps. Veuillez noter que les marchés des cryptomonnaies sont très volatils et que les performances passées ne garantissent pas les résultats futurs. Il est essentiel de mener des recherches approfondies et de tenir compte de votre situation financière avant de prendre toute décision d'investissement.

Rewards Edge Cases
Q1: Is it possible that if a user supplies certain asset on AAVE V2, instead of just receiving equivalent number of Atoken, the user can also receive a non-Atoken? Q2: If I supplied 1000 USDC on AAVE V2, I am subjected to receive equivalent amount of aUSDC and get intrest on it, is it possible I can receive other rewards too without doing anything? If yes how?

ua.eeeh2.co mining pool
Hello,. A person who advised me to buy cryptocurrencies. I have known her for a short time. I got her contact from a dating site. She advised me, without forcing me, to open an account on Trust Wallet and DefiWallet, to deposit USDT and make them grow by mining ETH. The platform I use, which she recommended, is Defi Wallet, and my USDT is invested in the ETH 2.0 mining pool (link ua.eeeh2.co). I have been in the mining pool for a week and have already made several transactions. I also managed to withdraw USDT from the wallet and convert them into euros. Could you confirm this adresse ua.eeeh.co is a real mining pool? Thank a lot

Reentrancy Vulnerability
Hello everyone , I've noticed that the offer function uses the .call{value: amount}("") method to send Ether to the recipient's address. Could anyone provide insight into whether this function is indeed vulnerable to reentrancy and suggest any best practices or modifications to mitigate such risks? function _offer(address to, uint256 amount) internal { balance -= amount; (bool success, ) = to.call{value: amount}(""); if (!success) { revert TransferFailed(address(0), address(this), to, amount); } } `
