A proposed "Shielded Bitcoin" design would publish encrypted transfer data on the Bitcoin blockchain while leaving validity checks to separate software anyone can run, unlike Zcash, which enforces its private payment rules inside its own chain. As a result, a Bitcoin transaction could confirm even if the shielded payment within it fails checks. Users could reconstruct payments with wallet keys and share viewing keys with auditors without granting spending rights. Zcash shielded pools held about 4.9 million ZEC on Friday, up 14% from July 30, roughly 29% of issued coins, worth about $7.8 billion. The paper arrives as developers pursue practical privacy for payroll, business payments and everyday spending, since ordinary bitcoin transactions permanently expose addresses and amounts.

    New bitcoin privacy protocol just dropped Shielded Bitcoin uses “shielded notes” and “PIPEs” to make larger private payments. Not meant to compete with L2s such as Lightning and Ark for frequent, smaller payments. https://t.co/iOj8TaUxM1

    No soft forks, no bridges, no operators, just Bitcoin. We’ve put a lot of work into thinking carefully about the security of Shielded Bitcoin and about what information the protocol reveals. And this is just the beginning! https://t.co/5kMgCafcHU
