Ethereum client Parity özgü added support for on-chain private transactions in its latest software update, providing developers with the ability to create and deploy encrypted smart contracts.

Released on Tuesday, Parity 1.11.1-beta introduces several new features to the software client, which remains popular even though several bugs in Parity’s multisig smart contract libraries have given the company a black eye — and have caused users to lose access to hundreds of millions of dollars worth of funds.

The most eye-catching feature in the new release is the support for private transactions, which allows developers to encrypt smart contracts. The underlying code is stored in a private contract, which is permissioned and thus not publicly viewable. The private contract is then wrapped in a public contract, enabling authorized users to interact with it on-chain without exposing the private contract’s code.

From the release notes:

“Private Transactions make it possible for you to store, modify, and view code and state for a set of permissioned participants. This means that with private transactions on public chains, all contracts and transactions are accessible only by those with the right permissions viewable by anyone, but now you can work with others in the open behind strong encryption.”

And here’s another explanation, posted on Reddit by Parity developer Maciej Hirsz:

“Private Transactions are basically Private Contracts, where the state and the code of the contract are both encrypted. Transaction is first sent off-chain to a number (specified by the contract) of Validators that all have to agree on what the new state is, then you…
