Researchers' Shielded Bitcoin (BTC) Design Sizes Private Transfers at 700 Bytes

Researchers proposed Shielded Bitcoin (BTC), a design using Zcash-style encrypted notes for private transfers. Each private transfer weighs approximately 700 virtual bytes. The proposal currently lacks a deposit mechanism, meaning users cannot yet move funds into the shielded system. The design aims to enhance Bitcoin privacy while maintaining compatibility with the existing network.
