When it comes to blockchain ledgers, many people fall into a binary mindset—either completely transparent or fully hidden, with no middle ground. But in the real world of finance, operations are never so absolute. An interesting design approach worth noting is that ledgers can remain private while the system still verifies whether transactions follow preset rules. In other words, transaction details can remain confidential, but the accounting is crystal clear, preventing anyone from playing tricks. This approach is actually closer to traditional financial operations—banks do not disclose your account details publicly, but every transaction must comply with regulatory requirements. For financial institutions, this could be the key breakthrough in adopting blockchain technology. Privacy and verifiability are no longer mutually exclusive but can be achieved simultaneously.
