Horizen will stop processing transactions on its L3 network at 18:00 UTC on November 5th when Base activates the Denim upgrade. Bridging to Base closes at 13:00 UTC on November 4th and L3 staking rewards end on October 25th, so users should migrate their assets beforehand.
Refer to the official tweet by ZEN:
📣 Horizen update 📣
TLDR: Horizen is changing. The Horizen L3 is winding down over the next two weeks.
Users should bridge their assets to Base at their soonest possible convenience, including unstaking and withdrawing any funds from ZEN staking on the Horizen chain. A new ZEN… pic.twitter.com/vjROuzJGyg

ZEN Info
Horizen is a zero-knowledge-enabled network of blockchains powered by the largest node infrastructure in the industry. Blockchain interoperability is enabled by the Zendoo protocol, which uses SNARK-verification and allows for complete flexibility in sidechain type, consensus, speed, and privacy. Cryptographic verification of networked chains offers massive scale, and the network currently supports up to 10,000 sidechains with a throughput limit of 10,000,000 TPS.
Zendoo makes Horizen a permissionless network of blockchains. Developers can deploy their blockchains within the ecosystem using a variety of SDKs. The first set of SDKs, Blaze and Latus, deploy blockchains based on IOHK’s provably secure Ouroboros proof-of-stake protocol. Blaze offers high-speed chains that declare their own certifiers and can run up to 1,000 TPS, while Latus uses a recursive SNARK composition for full decentralization. The next set of SDKs will include EVM integration for Ethereum smart contract compatibility.
Horizen’s native cryptocurrency, ZEN, can be staked to participate in the network.
