Tezos to Implement Cash Privacy Features

Tezos to Implement Cash Privacy Features

Tezos developers are planning a network update called Edo. The implementation of the Zcash Sapling library will allow you to hide transactions in the Tezos blockchain.

According to the statement, Tezos developers Nomadic Labs, Marigold and Metastate have submitted several proposals for the next update of the network – Edo. The update will bring privacy features and other improvements.:

“No other major smart contract platform yet supports these features, but we can add these tools directly to the blockchain.”

In mid-November, the developers of Tezos successfully activated
the Delphi update, which significantly reduced the fees for smart contracts. With this move, Tezos hopes to attract the creators of DeFi projects.

“Although Delphi was launched on November 12, it was offered on September 3. Over the past months, we have worked hard on the core Tezos software and made significant improvements that we want to share with the users of the network, ” the developers said.

The first new feature in Edo will be the implementation of the Sapling library, originally developed by Electric Coin Company for the Zcash blockchain. As with Zcash, Sapling will allow you to hide transactions. Tezos developers will be able to integrate this feature into their smart contracts and applications for which privacy is important.

The second addition to Edo will be the ticket system. According to the developers, it is “a convenient mechanism for smart contracts to grant portable permissions to other smart contracts or to issue tokens.” According to the statement, although to some extent similar functionality can be achieved using already existing methods, tickets should greatly simplify the process for third-party developers.

The Edo introduces the so-called “fifth period”, which will simplify the deployment of updates in the future. Currently, it takes about one block (60 seconds) to launch new versions of the protocol after the voting is completed, which makes it difficult for some “bakers”, indexers and other users of the Tezos network to smoothly update their nodes. To fix this problem, the developers of Tezos suggested extending the update period so that users have more time to prepare.

“Under the new system, instead of four periods of eight cycles during voting, we propose to use five periods of five cycles. The “fifth period” will be five cycles between the adoption of the new protocol and the time of its launch, which, in our opinion, will help to ensure a smooth transition between the protocols, ” the developers write.

In addition, the Edo proposal contains several minor bug fixes to further improve performance and reduce gas costs.
