Bitcoin can enhance your privacy if this protocol improvement proposal is approved

Bitcoin is a network whose transparency can work against you at times, so every proposal to improve your privacy is welcome. This is so as long as the solution does not put users at risk.

Andrew Chow, Bitcoin developer and engineer at the Blockstream company, presented a improvement proposal to the Bitcoin protocol or BIP, for its acronym in English. Said proposal implies changes in the functioning of the descriptors of the transactions with the purpose of optimizing their level of privacy.

The descriptors of a Bitcoin transaction they are a kind of script written in programming language that dictates each of the steps that she must fulfill.

Chow explained his proposal through the Bitcoin developer mailing list, where he provides technical details of the procedure to execute the change he proposes. It is about allowing the use of a single descriptor for both external and internal transactions.. By this he refers to transactions from other Bitcoin addresses, on the one hand, and to the change or change that is received when the entire available balance is not spent, on the other.

Currently, in accordance with BIP32, most wallets use separate routes to receive transactions from other addresses and for change. This is in order to keep Bitcoin as private as possible. However, Chow presents a hypothetical scenario in which the external addresses of a Bitcoin wallet are leaked, the attacker would have access to information about when and how much said wallet has received and spent.

Several developers gave Chow feedback on his proposal and confirmed that wallets like Trezor and Sparrow are already prepared to support a scheme like the one he presents. According to developer Dmitry Petukhov, Bitcoin wallets currently use only external and internal pathways; so that Developing improvements designed for other types of roads would only bring unnecessary complications to the proposal..
