Over the last few years, developers have been creating Bitcoin privacy tools, as we've seen with Coinjoin, Coinswap, Lightning Network and many other technologies.
However, the idea arose of creating static addresses that can be reused, not linking to the original or traditional address as we already know Legacy, Taproot and Segwit.
In 2019, Rust Russell, a Lightning Network developer, presented a draft of BOLT12 on the Lightning-dev mainlist. Since then, it has gained development and adoption as seen in Phoenix, LDK, Core Lightning and many others. This allows the invoice to be reused several times.
As for Silent Payments, it was created in 2023, proposed by the developers Ruben Somsen and josibake, allowing users not to reuse addresses and promoting greater on-chain privacy (L1). As mentioned in BIP-352 below:
This document specifies a protocol for static payment addresses in Bitcoin without on-chain linkability of payments or a need for on-chain notifications.
What we can see is that these addresses will be a trend in Bitcoin, giving it more privacy without the need to activate soft forks.
