Concurrency locks and token-aware wallets
The practical edge since the last check is about keeping high throughput correct — and keeping tokens intact when people actually use wallets.
Teranode has been spelling out concurrency controls inside the stack. UTXO Lock Records temporarily lock referenced outputs during validation so no other transaction can claim them at the same time, aimed at race-free behavior at 1M+ tx/sec. Two-Phase Commit is framed the same way: validation, UTXO update, and block assembly either all succeed or all fail, avoiding partial states across distributed services.
On the application side, LocalBSV has shipped a clearer BSV-21 Token Wallet inside /Wallet: send via Directory and Multi Send, receive via QR/address, send history, and a Token Locker. That pairs with a direct call to wallet providers to recognize BSV-21 UTXOs and stop burning assets through outdated or untested sweeps — the same friction that has kept coming up around auto-sweep behavior.
Infrastructure examples are also showing up beyond node marketing. LightBSV published three decentralized, distributed sample apps built on BRC-100 and SPV for a high-throughput Teranode environment, with patterns and code linked for others to inspect. The broader point from that lane remains: when throughput rises, wallet and protocol-layer choices (not only node capacity) will decide what actually works.
The current pulse is less about new TPS headlines and more about correctness under concurrency and wallets that do not destroy the tokens they claim to support.
