Recently, I noticed a quite pragmatic privacy computing project - TEN Protocol.

What it does is actually not complicated: it builds a Layer 2 network that can process data in an encrypted state. You can understand it as the entire computation process being enclosed in a sealed black box, where outsiders cannot see what is happening inside and can only see the final output.

This design is somewhat like doing a complex calculation where the scratch paper is completely obscured, and others can only see the answers you write on the answer sheet. The data remains encrypted throughout its flow on the chain, which does not affect verification and settlement while also preventing the leakage of sensitive information.

For scenarios that require handling private data on a public blockchain, this technological approach does address some real pain points. After all, many commercial applications or personal transactions do not want every operation to be publicly scrutinized.
