The Horizen team has announced a “Beta Preview” testnet launch of its sidechain solution, Zendoo.

Zendoo is a decentralized sidechain protocol and scaling solution that will enable businesses and developers to create fully customizable blockchains which are mapped to the Horizen public mainchain.

According to the Horizen team, the Zendoo sidechain model is designed to tackle some of the biggest roadblocks hindering the real-world implementation of blockchain solutions. Zendoo will solve problems like scalability and flexibility, privacy and audibility, as well as decentralization.

Talking about scalability and flexibility, Zendoo’s architecture is designed to prioritize functionality. Blockchains and other types of computing systems can be deployed as sidechains. This modular structure gives rooms for massive scalability since the Horizen mainchain’s primary function is to provide a common token of value and to ensure that applications conform to standards.

Whilst it is possible for the mainchain to verify sidechains on Zendoo, the mainchain does so without knowing the internal structure of the sidechain. This enables the creation of privacy-preserving blockchain applications.

Zendoo does not rely on third parties for backward transfers. Such an approach removes the need for trusted parties. By leveraging on zk-SNARKs, the mainchain can effectively validate withdrawals.

Speaking on the development, Rob Viglione, Co-founder and Team Lead of Horizen said:

When we began in 2017, we chose to go down the hard road of creating our own innovation to solve some of the biggest problems in blockchain – scalability and application privacy.
Zendoo is the last mile of this marathon. We are delivering the culmination of a two-year investment in significant innovation that solves real problems in the marketplace and gives businesses a reason to build on a public network that didn’t exist before.
