Zano announced that its Zenith upgrade is now in implementation, with a network transition planned for 2027, subject to testing, analysis, and review. The privacy-focused blockchain targets 15-second blocks and four to six confirmations under the proposed design. Zenith emerged after years of research into Zano's hybrid proof-of-work and proof-of-stake model revealed structural limitations tied to mining, prompting collaboration with blockchain research firm Common Prefix to explore pure proof-of-stake alternatives. The upgrade builds on more than 12 years of privacy research and extends Zano's existing Zarcanum privacy technology. Alongside the Zenith announcement, Zano launched a new forum for community discussion and technical support.
Zano Announces Zenith Implementation Targeting 2027 Network Transition
Zano has not announced an activation date, and the proposed operating parameters remain subject to network-level validation. The team initially sought to strengthen the combination of proof of work and proof of stake, but repeated design efforts continued to inherit limitations tied to mining. After encountering those structural constraints, Zano and blockchain research firm Common Prefix explored pure proof-of-stake alternatives.
The collaboration produced two research paths, StakeNote and Zenith. Zano selected Zenith because it extends the privacy machinery already built into the network through Zarcanum rather than requiring a separate architecture.
Zenith Introduces Private Staking Without Exposing Validator Balances
Conventional proof-of-stake systems often expose validator balances, staking histories or links between participants and their funds. That model would conflict with Zano's privacy goals, which center on hiding balances, transaction histories and user identities. Zenith is designed to determine whether a participant is eligible to produce a block without revealing the amount staked or creating a permanent public link between outputs and identity.
"Privacy projects should not have to choose between stronger consensus security and protecting their users' privacy," Andrey Sabelnikov, co-founder and core developer of Zano remarked. The Zano developer added: "Zenith is the result of more than 12 years of research into how a network can gain the benefits of modern proof of stake while preserving the privacy that users expect from Zano."
Proposed Design Reduces Block Time to 15 Seconds
Under the proposed design, Zano's block time would fall from about one minute to roughly 15 seconds. The recommended confirmation threshold would decline from 10 blocks to between four and six, cutting typical confirmation time to about 60 to 90 seconds. Zano detailed that six Zenith confirmations are expected to provide stronger security guarantees than the 10 confirmations used today, although those figures remain targets until testing is complete.
Faster settlement could improve private payments, wallet transfers, decentralized trading, bridge activity, and application integrations. For users, the main change would be quicker confidence that a transaction has become part of the accepted chain without weakening the privacy protections surrounding the transfer.
Ephemeral Blocks Address Chain Growth From Increased Block Frequency
In the announcement, the team noted that a fourfold increase in block frequency could ordinarily increase storage and synchronization demands. Zenith addresses that issue through ephemeral blocks, which retain full data near the chain tip but become more compact after an epoch is finalized. Under the proposed parameters, each 10-minute epoch would contain 40 blocks.
After finalization and a retention period, most blocks would be reduced to compact cryptographic records that preserve the chain structure and essential commitments. One block reward per epoch would remain permanently recorded in Zano's global output index, while the other 39 reward records would not require permanent indexing. An optional archival mode would preserve complete historical data for operators who want it.
Zenith Activation Would Eliminate 262,800 ZANO Annual Mining Issuance
Proof-of-work miners currently receive about 720 newly created ZANO per day, equal to roughly 21,600 ZANO per month or 262,800 ZANO per year. Once Zenith activates and proof-of-work mining ends, that portion of issuance disappears.
Zano argues the shift would reduce the amount of newly created ZANO entering circulation and remove some cost-driven selling associated with electricity, equipment, hosting, and maintenance expenses. The project stopped short of making a price forecast, noting that demand, liquidity, adoption, and broader market conditions will still determine ZANO's market value.
Zano Launches Official Forum Alongside Zenith Announcement
Zenith represents Zano's planned move from a hybrid network launched in 2019 to a pure proof-of-stake system rooted in Zarcanum's privacy technology. For holders and node operators, the proposal combines faster settlement, lower issuance, and private staking without exposing validator balances. The 2027 transition remains conditional, but Zano has now established the technical direction for its next consensus era.
Alongside the Zenith rollout, the team launched the official Zano Forum as a dedicated hub for questions, technical discussion and community support. Members can verify their on-chain aliases to receive a visible badge, giving users a clearer way to distinguish authenticated accounts from unverified participants and reducing uncertainty over who is providing information.
FAQ
What did Zano announce about its Zenith upgrade?
Zano announced that its Zenith upgrade is now in implementation, with a network transition planned for 2027, subject to testing, analysis, and review. The upgrade targets 15-second blocks and four to six confirmations, representing a shift from Zano's hybrid proof-of-work and proof-of-stake model to pure proof-of-stake.
How does Zenith change Zano's block confirmation time?
Under the proposed design, Zano's block time would fall from about one minute to roughly 15 seconds, and the recommended confirmation threshold would decline from 10 blocks to between four and six. This cuts typical confirmation time to about 60 to 90 seconds.
What is the economic impact of eliminating proof-of-work mining in Zenith?
Proof-of-work miners currently receive about 720 newly created ZANO per day, equal to roughly 262,800 ZANO per year. Once Zenith activates and proof-of-work mining ends, that portion of issuance disappears, reducing the amount of newly created ZANO entering circulation.
