My 2 cents on x402: - It is just a communication standard set to streamline the services to opt into crypto as the payment rail instead of credit card system. Without it, you can still just do it via P2P standard to inform of your wallet address as a vendor, and receive the payments, then settle the services. - The response code can be 402, can be 200 but with a metadata describing the next step to pay, could be anything, but the idea is to ask for service, respond with the price tag, and pay the price, then you get your service. If you swapped the blockchain part with just sth like a random @WechatPay, @PayPal, the user experience will still be the same. - Business in the states who usually have a complete business, credit card, KYB setup, with users all have access to credit cards won't have much upsides to x402, @stripe is already their fav platform, unless stablecoin adoption in the states becomes mainstream. - Business who has interests in launching their own stablecoin to farm T-bills, so that their payments operations suddenly becomes a for-profit product. (insights from yesterday's @WPReadingClub event) - Business that operates in less financial infra established markets could really benefits from this as onboarding as a service vendor that accepts crypto payments is literally PERMISSIONLESS, and anybody with a cellphone and internect could open up a payment wallet to start using the services. - Payments on x402 has no transaction fee needed but only some small gas fee regardless of the transaction amount. Unlike visa, mastercard, amex who charges from 2.5-3%. - x402 with Agents is an amazing upside, but it comes with preconditions, we are still 2 steps away: 1. step one is to have good and reliable agents who can actually do trades that won't hallucinate, predictable, and has a boundry/policy mechanism set for bounding behaviors. 2. step two is to have actual communication and trades between the agents 3. x402 will then become actual usable protocol for the A2A usecases. - The customizability of facilitators could open up web2 like payment experience that was not possible before on web3. It's all because of the "signed intent" that facilitators can settle onchain when they want to. It's like a check sent out waiting to be claimed. so when to upload the intent(from immediately all the way to couple days for security garantee), how they upload the intent(single or batched?), which ones to upload?(censorship ability if thats part of their business requirement), and more. One thing that's inevitably going to happen is more people are going to use crypto as the payment rails for its efficiency compare to everything else out there. The only problem is the onboarding atm, which is growing at an unstoppable rate. So don't sleep on x402, go build infra for it, build services on top of it, create modular monetized internet on top of it. g402

1/24 Excited to release the @AggLayer Unified Bridge Tutorial This tutorial explains the design and usage of Unified Bridge and Bridge-and-Call on AggLayer. Here's the breakdown: Architecture: ❓ WTF is Unified Bridge? ❓ What? Unified Bridge has 4 Merkle Trees? ❓ The components that make Unified Bridge Tick! ❓ Why is Unified Bridge secure? Dev Interfaces: ✉️ Bridging Assets and Messages using UB. ✉️ & 📲 Bridge-And-Call: Literally doing bridge, and call, all in one txn. Example Transactions using Unified Bridge: 🌉 Bridging Asset from L1 👉 L2 🌉 Bridging Message from L2 👉 L1 🌉 Bridge and Call from L2 👉 L2 🌉 Bridge sth from Lx 👉 Ly 👉 lz (?) Tutorial Link can be found here: github.com/BrianSeong99/A…

Weird thing in Crypto: - @0xPolygon working with Jio to bring crypto to India, changing lifes, token price not pumping. - Trump decides to launch meme coin on @solana, fandom, and token price sky rockets. Ppl ask whats the value in Crypto: it’s attention. the value is still not yet on problem solving. Don’t get too carry away with the trend. Or blockchain can never prove its value. If you have been a solid builder trying to make blockchain useful, your time will come. If trust, then build, timing is always not mine to control.

Won the @SuccinctLabs track at @ETHGlobal Trifecta, and this is only the beginning. We’ve built #zkHyperliquid thats is powered by #SP1 zkVM (and @Agglayer will also be added in the future as App bridge📈) I want to share more about what we've built, but will do it properly, it's a new paradigm for Apps built on blockchain. 👀 Stay tuned, Sharing this week 🤩 Best team, built with @0xRouss & @saugardev 🙏 Appreciate the judges for the nomination!

Unified Bridge of @Agglayer Video Explanation coming soon💜

Today, I found out that the founder of a hugely renowned zk company watched my Plonky3 tutorials to learn about it, and he liked them a lot. It’s surreal—earlier this year, I was in fact diving into their content to learn ZK myself. Moments like this remind me how life works in crazy, rewarding ways. Stay hungry. Stay foolish. Keep building, and you will find yourself progressed so far that you can build anything! 🚀 Some of the tutorials I have built for @0xPolygon Plonky3: - Plonky3 Introduction & Fibonacci Example: github.com/BrianSeong99/P… - Plonky3 Constraint Degree Introduction & RangeCheck implementation: github.com/BrianSeong99/P… More coming early next year! (#howtowritesimplezkVMinplonky3?)

Planning for my 2025: 💪 Health is No.1, both mentally and physically. I have been exercising at least 3 times a week last month and feel Great, and I will keep doing it this year. 健康是革命的本钱 🧠 Brain Engagements: Having long-term learning habit habits is super beneficial, life just feels much more fulfilling each day. I have been learning Japanese for an hour every day since October and hopefully, I can do a Japanese workshop by the end of this year. ✏️ Learn & Progress: Never work for the sake of work, it should be helping you learn and progress, and I am extremely fortunate at @0xPolygon to be in this position. I will continue to Make new useful contents, keywords: #zkVM, #CrossChainProtocol, #AIAgents. Technical Contents that I have made / making can be found here: github.com/BrianSeong99/A… 🏗️ Build: I have mentioned multiple times how much I believe in Verifiable Computation, starting way back in 2023 when I first saw @0xPolygonMiden and @RiscZero, and have been diving into this for quite a while now, probably this year is the best time to build something on for this problem space, and I'm ready to build sth! 🫂 Last year wouldn't be as meaningful and fruitful without the support from all my friends, colleagues, mentors, and families. ⌚ Cherish the people and the time you spend together, time is fair to everyone, and I truly am grateful for everyone who has spent time with me last year, wish you all the best in 2025!

Pessimsitic Proof of @Agglayer running in @RiscZero zkVM🔥 Running in CPU vs in GPU is day and night difference. 🫡 GPU is the way for Proof Generation I ran Risc0 zkVM using their GPU mode and OMG it took only 10% of the time that it took for Pico zkVM.

In the alt-VM L2 future, seems like only @AggLayer will be able to support them as long as they can produce Pessimistic Proof. - Super Chain @Optimism requires L2s to be built in op stack - Elastic Chain @zksync requires L2s to be built in zk Stack - Gwyneth @gwyneth_taiko requires based rollups to be EVM equivalent and use the same storage tree format Thoughts?🧐

Unify Bridge Workshop Last week at AggSummit @AggLayer Agglayer Unify bridge is the infra that help facilitate Cross-chain communication on AggLayer, it supports: - BridgeAsset & ClaimAsset: token transfer interface - BridgeMessage & ClaimMessage: cross-chain data transferring interface - Bridge-and-Call: interface to call any smart contracts on any chain that's connected to AggLayer. Here's a complete explanation of the infra, its source code, it's architecture, and how to use it. github.com/BrianSeong99/a… Happy coding🤌

Use any dapps from any chain on @Agglayer

AI, RWA, DEFI, NFT, BRIDGE, and many more. They all have to run on a powerful Unified Cross-chain enabled infra to scale for everyone. And Thats @Agglayer.

There's been a lot of praises💜 for @0xPolygon PoS Lately. Perfect opportunity to dive in and understand how is Polygon PoS work ! 🍂 Thanksgiving is 🏗️ ThanksBUIDLING ! This repo explains how was PoS designed that made it so ahead of its time. 🚀 github.com/BrianSeong99/P…
