This question divides the two dominant paradigms: <strong>Price-Centric Exchange (PTCEX)</strong> and <strong>Timestamp-Centric Exchange (TTCEX)</strong>.</p> <h2 id="ptcex--the-price-centric-paradigm">PTCEX — The Price-Centric Paradigm</h2> <p>Almost every major exchange today — Binance, Coinbase, Kraken, Uniswap — follows the PTCEX model. Under this paradigm:</p> <ul> <li><strong>Primary focus</strong>: Efficient price discovery</li> <li><strong>Core mechanism</strong>: Order books (CEX) or AMM curves (DEX)</li> <li><strong>Timestamp role</strong>: Timestamps are auxiliary metadata; price is the signal</li> <li><strong>User experience</strong>: You see the best bid and ask; you execute; time is a side effect</li> </ul> <p>PTCEX works well for retail trading where price is the dominant concern. But it treats time as a passive byproduct of market activity rather than an asset in its own right.</p>
