Not many have noticed one thing about Bitcoin that I consider highly underrated: Silent Payments (BIP-352).
The concept is quite wild from the historical Bitcoin perspective, but absolutely necessary in our current circumstances. You can publish a single permanent Bitcoin address that starts with sp1q... and distribute it to everyone or simply publish it online for donations.
Unlike a classic Bitcoin address, this address cannot simply be copied into an explorer and reveal everything you have received. Technically, when someone sends you BTC, they are not paying directly to your sp1q... address.
Their wallet uses the cryptographic data of your Silent Payment and the transaction to create a unique Taproot output. So, if 10 people send you Bitcoin, the blockchain will see 10 different outputs, with no obvious public link between them.
Your wallet can recognize those belonging to you, thanks to the scanning key. And this is a great idea: a permanent Bitcoin identity you can openly display without turning your financial history into public information.
Of course, this doesn't make Bitcoin completely anonymous, and you can still create visible connections by spending your UTXO incorrectly. But for the purpose of receiving payments, the concept is incredibly elegant.
You can test this directly with Cake Wallet. Silent Payments / BIP-352. Clearly, this is a Bitcoin feature that almost no one has ever heard of.
However, in a world of fragmentation where American regulators may label cryptocurrencies as red and render them non-payable, or when accusatory judgments come to your wallet for public donations, the idea is just wonderful.
