People often waste time debating which blockchain is the best. There is no "best" blockchain. Each one has its own strengths and weaknesses, and most people online are too tribal to admit it. Bitcoin is the slowest blockchain. But at the same time, it is the most secure. That's not a coincidence. That's the trade-off. Speed and smart contract capability come at a cost, and that cost is security. The faster and more programmable a blockchain gets, the bigger its attack surface becomes. Think about it: - Bitcoin → the only way you get hacked is if your private key is stolen. That's it. - Ethereum & Solana → people lose millions every year to faulty smart contracts. One bad line of code and your funds are gone forever. The $600M Ronin hack. The $320M Wormhole exploit. None of that happens on Bitcoin, because Bitcoin doesn't try to do what Ethereum and Solana do. Complexity is a feature. Until it isn't. So before you say Bitcoin is "outdated" because it only does 7 TPS - ask yourself: how much is absolute security worth to you?

If you've been building on #Tron lately, you already know energy costs have gotten painful. A single transfer of 1 USDT can cost 13.4 TRX (~$4.12 USD). For any platform like a crypto payment gateway or a stablecoin payment processor moving huge volume, that adds up fast. At Fystack, our users felt it. So we built a fix. We've integrated TronZap, an on-demand energy rental provider, directly into our withdrawal and sweep automation flows. Here's what that means in practice: - Rent 131,000 ENERGY in 1 our for just 5.5 TRX (~$1.69) - enough to make a USDT transfer - Up to 60% reduction in transaction costs - No need to run large-scale staking operations like Binance or Bybit to get free energy. - Fully automated, no manual intervention required Instead of locking up capital in staking just to offset fees, you rent the energy you need, when you need it. Clean, efficient, and cost-effective. This is now live on Fystack at fystack.io lnkd.in/gUTh_ixA If you're managing crypto infrastructure on Tron and high energy costs are eating into your margins, I'd love to hear how you're handling it or show you how we did.

According to Chainalysis, illicit crypto transactions reached $154B in 2025, with #stablecoins accounting for 84%. Most RWA and stablecoin B2B payment projects follow the same pattern. The first 6 months are spent on fundraising, legal structuring, and refining the business model. But that is only 20% of the real challenge. Sooner or later, reality sets in: financial crime on blockchain. That is when many teams realize a hard truth. If your infrastructure still relies on centralized SaaS wallets, you are effectively running on rented rails. This means you cannot control transaction signing logic or stop risky transfers at the entry point. That is why the next generation of payment infrastructure is moving toward policy as code and self hosted architecture. 🔹 AML rules are enforced automatically through code 🔹 Risky wallets are blocked using real time data 🔹 Businesses retain ownership of their keys and operational data In 2026, the real competitive advantage will not come from slightly better UX. It will come from infrastructure sovereignty, the ability to fully control your own payment infrastructure.

Stablecoins didn’t become relevant because of hype. They became relevant because global payments are still broken. Cross-border transfers: slow, expensive, opaque. Stablecoins quietly found traction where legacy rails fail most 👇

How do you move $1M to a supplier instantly on a Saturday? Traditional rails like ACH involve batch processing delays (T+2). Tokenized deposits enable atomic T+0 settlement. But to work safely, they require a precise synchronization between the Bank's Ledger and the Blockchain. Here is the End-to-End Workflow 👇

I want to forward this video here to show why it would take a lot of effort to craft a perfect product. From @thicody perspective, the button label "withdraw" makes perfect sense, but it makes zero sense to normie, it should be "send" or "transfer". Now, 10x tuning into every detail of your product. --- People says that 1st time founder do product first, 2nd time founder do distribution first. I want to argue: great founders - who love what they do - obsess on product, "commercial" founders - who seek a quick exit - do distribution.

Happy New Year everyone 🎉 We just want to say thank you to the @fystack community, our users, and everyone who has contributed or supported us along the way. Whether you tested the product, gave honest feedback, opened an issue, shared ideas, or simply believed in what we’re building, it truly means a lot. Fystack would not exist without this community. Last year wasn’t easy, but it helped us build strong foundations. This year, our focus is simple: build better, ship faster, and create real value for the people who trust us. Really grateful to have you here with us. Let’s keep building together 🙏 Fystack Team

1/ 2025 was the year Superteam Vietnam stopped being “just a community” and started behaving like an economic engine. Despite legal uncertainty, noise from other chains, and a tough macro backdrop — the builder flywheel started moving.

If you are building a decentralized protocol on Solana Or you have one already (under 1 million mcap) I will invest and bring funds to you before the end of the year We need more of the real thing

Devs should be careful when interacting with open source code. If you accidentally install malwares on your machine, hackers will collect these data. Recomendation: - Always set a strong passphrase for ssh key - Avoid static AWS credentials at all cost, never put AWS credentials in ~/.aws/credentials - Be extermely careful with open source code, vet it carefully, run in sandbox environment This is from the Bybit hack exellent breakdown blog post by Elastic Labs team: elastic.co/security-labs/…

This is our second submission. First submission, won nothing but we acquired customers, iterate from feedback, submited again. Regardless of the result, the team will just continue to build and ship relentlessly
Fystack@fystack

Building is a long game. At @fystack, we’re building enterprise-grade stablecoin custody for teams - the fastest way for fintechs and Web3 companies to go on-chain securely. The @solana Cypherpunk Hackathon was an important touchpoint to validate how we automate stablecoin and digital asset workflows on Solana, with strong team controls and security by default. Thanks to @colosseum for the Honorable Mention, and to @SuperteamVN for the support. Congrats to all!
