To carry global level payment traffic by 2026, "fast" alone is not enough, it also needs to be "unobstructed". This involves @ SeiNetwork's killer move - Parallel Execution. Let's break it down into easy to understand principles and see what it looks like in real life. 1、 How can Sei prevent traffic congestion through 'parallel execution'? Traditional blockchains (such as early Ethereum or Bitcoin) process transactions like a supermarket with only one checkout counter. Create a four grid image with the uploaded image as the protagonist Traditional mode (serial): Whether you're buying a bottle of water or a whole vehicle, everyone has to line up. If someone is slow to checkout earlier (such as a complex NFT minting event), then everyone who wants to buy water later (simple transfer) has to do it. This is the reason for "congestion" and "skyrocketing gas fees". Sei's model (parallel): Sei is like a large supermarket with dozens of checkout counters. How does it work? (Intelligent diversion) @SeiNetwork's system is very intelligent, it takes a glance at "who is related to whom" before processing transactions: Non interfering transactions, running simultaneously: If A transfers money to B, C transfers money to D. These two things do not affect each other, Sei will make them happen simultaneously on different "lanes". Result: Efficiency doubled without occupying resources. Transactions with conflicts, queue up and run: If A transfers money to B and at the same time A wants to transfer money to C. Because they all involve A's wallet, it is necessary to queue up and follow the order. What does this mean for 'preventing congestion'? On Sei, 'Neighbor noise won't affect your sleep'. Previously, on other chains, if a popular game or Tugou project suddenly became popular, the entire network would crash, causing you to have to wait for half a day or even fail to transfer dozens of yuan to your friends. But on @ SeiNetwork, that popular game will occupy its own "lane", and your payment transaction is taking another idle "lane". That's why Sei can serve as the core reason for the financial foundation - it ensures the certainty of financial transactions. 2、 Actual Payment Application Cases on Sei in 2026 Based on Sei's existing collaborative ecosystem (Circle, PayPal, etc.) and the implementation of MIG and Giga technologies, the following are several typical application scenarios we will see in 2026: 1. Cross border remittance application: For example, friends working in Singapore have to remit living expenses to their parents in China every month. Previous pain points: bank wire transfers take several days and incur transaction fees of several tens of dollars; Alternatively, you can find a currency exchange store, where there is a risk of exchange rate differences and card freezing. Experience on Sei: Now all you need to do is open the app, recharge new coins directly, and the backend will automatically switch to native USDC (Circle's native integration on Sei, no bridging risk). Click send, within 400 milliseconds, USDC will arrive at the parents' digital wallet or the bound compliant fiat currency withdrawal channel. Cost: The handling fee is less than 0.01 US dollars. Bottom level technology: Utilizing parallel execution, even if someone is speculating on coins on the chain, Mr. Zhang's remittance will arrive in seconds. 2. Creator economic payment: Scenario: A live streamer with millions of followers is broadcasting. Fans want to give small red envelopes (such as $0.5) as a reward. Pain point: On the Ethereum mainnet, tipping $0.5 may require paying a $5 gas fee, which is completely impractical. Experience on Sei: Fans click on the screen, and a few cents in tips are instantly credited to their account. Sei's ultra-low rates make "Micro payments" possible. The anchor received PYUSD (PayPal USD), which can be directly consumed at global merchants that support PayPal. 3. Institutional level settlement gateway: Scenario: A Hong Kong hedge fund wants to buy US treasury bond token products (RWAs). Experience on Sei: This is a large-scale, low-frequency operation that requires extreme safety. Transactions are conducted through MIG (Market Infrastructure Grid). The system will automatically check the compliance qualifications (KYC) of the fund and conduct atomic exchanges through the wallet hosted by Coinbase Custody. Funds are settled entirely within a compliant walled garden without passing through any unsafe cross chain bridges, with real-time T+0 arrival (traditional finance may require T+2). @SeiNetwork's "parallel execution" solves the problems of "fast" and "stable", and these payment cases demonstrate the future of "cost saving" and "connectivity". Parallel execution allows you to avoid traffic congestion on the chain. MIG encourages large funds to enter the market. Giga ensures that even if hundreds of millions of people worldwide use it, the speed will not slow down.
