How to Reliably Confirm Blockchain Transactions Before Updating User Balances in a High-Traffic Application?
I’m developing a web application where users can purchase TON (Toncoin) on the TON Blockchain. My app is built using React for the frontend, Node.js with Express for the backend, and Firestore for data storage. The app currently has over 5,000 users, and I anticipate that up to 1,000 users might attempt to purchase TON within a single hour.
