ZenIP 42207: Complete Removal Of Shielded Pool From The Horizen Mainchain

 ZenIP 42207 for the complete removal of the shielded pool from the Horizen mainchain was submitted on January 4th, 2024. Here’s what it means.

This ZenIP proposes the complete removal of the shielded pool from the Horizen mainchain, achieving a wide range of various goals. This change builds upon the deprecation of access to the shielded pool enacted by ZenIP-42204 and is a response to the evolving regulatory environment around privacy tokens, re-confirming and showcasing the project’s strategic pivot away from privacy-focused features.

• Complete Disabling of Shielded Transactions: All functionalities related to the shielded transactions (z-addresses) will be completely deactivated, preventing any type of transaction related to the shielded pool.
• Removal of Related RPC Calls: RPC calls specifically related to shielded transactions, such as z_sendmany and z_mergetoaddress, will be deprecated.
• Migration Path for Users: A migration path with the necessary tools and guides will be provided to users to move their assets out of the shielded pool before the hard fork. Community support and detailed documentation will be available to facilitate this transition.
• Network Upgrade: The deactivation of the shielded pool will occur through a network upgrade at a specified block height (TBD). Extensive testing, community preparation, and communication will precede this upgrade.
• Communication and Timeline: Representatives of the Horizen ecosystem will communicate regularly with the community about the timeline, necessary user actions, and available support resources throughout the transition process.
•  

IMPORTANT: ZEN 5.0.0 is expected to be released in January and go live on Mainnet in February 2024. Once active it will not be possible to send any shielded transactions, including transactions to de-shield coins from shielded to transparent addresses.

ZenIP 42207 goes further than the hard fork originally announced with ZEN 4.2.0-rc1, ZEN 5.0.0 will completely remove the shielded pool. We strongly recommend that all users with existing funds in private addresses unshield their funds to their own transparent addresses using Sphere by Horizen or zen-cli before February 2024. After February 2024 it will not be possible anymore to transfer any funds inside of the shielded pool to any other address. Unshielding funds directly to exchange deposit addresses is strongly discouraged. Failure to remove ZEN from shielded pools prior to the hard fork will result in the loss of your ZEN.

Who is Eligible to Vote?

Any $ZEN holder can vote on improvement proposals, and those who hold (or who have been delegated) the requisite amount of $ZEN may put forth proposals to the community.

Voting power is determined by the amount of $ZEN you hold on the Horizen mainchain and on the Horizen EON chain. Therefore the more $ZEN you hold, the more voting power you have.
