Then they use zero-knowledge proofs to verify that a transaction is valid. To create another layer of privacy around transactions, some newer blockchain networks encrypt the information recorded in their distributed databases, so no external observers can read their blockchains.

(This has created a cottage industry of “ on-chain analysis” providers that offer insights into the state of crypto markets )

With Bitcoin, the progenitor of all cryptocurrencies, users can access the network without revealing their identities- but the balances and transaction histories of all addresses on the network sit in full public view on the blockchain. As blockchain experiments proliferate and become more complex, the proofs are being used by all kinds of players - governments, anarchists, entrepreneurs - to bake an extra layer of secrecy into new projects.Īdjusting the balance between "public" and "private" information has been a big part of crypto's evolution since the beginning.

Increasingly, new crypto projects are adopting mathematical techniques called zero-knowledge proofs, which allow users to verify that a certain piece of information is true - but without revealing the underlying information itself. One important shift right now is that the world of crypto is getting more, well, cryptic. Even as cryptocurrency markets have cratered, the underlying technology continues to evolve at a rapid pace - often in ways that governments would do well to pay attention to.
