About the coin (primary summary)

• What the coin is: Zecnero (ZMR)
• Mining algorithm: RandomX (v1) with modified Argon2‑salt (denoted as RandomX‑Zecnero)
• CPU‑only or not: CPU‑oriented (RandomX), positioned as mining on regular processors
• Brief description: Zecnero is a fork of the Zebra node from Zcash, retaining Sapling and Orchard shielded pools, but replacing Equihash with RandomX to remove the advantage of specialized hardware and make mining accessible on desktop CPUs. No premine, no ICO/dev fund, a founder stream is provided — 3 % of the block subsidy until the first halving (block 1 680 000).
• Where to mine/pool: not specified (the announcement only mentions testnet plans and nodes in North America and Europe)
• Wallet/links: Website, Protocol Specification, GitLab, Discord, X (Twitter) — specific URLs are not listed in the text
• Community reaction: Users express interest, plan to follow the Discord for testnet news; they ask about the need for testing on older and ARM hardware, the author confirms that correctness of the build needs to be verified, not just hash speed, and announces an upcoming testnet launch.

Summary of new messages about Zecnero (ZMR)

Main topic of new messages

Closure of the testnet phase and announcement of mainnet launch. Developers announced testnet readiness, mainnet launch in Q4 2026, and the introduction of the “Genesis Miner” competition system.

Key news/updates

• Testnet launched — official announcement with access to explorer.zecreno.org and pool pool.zecreno.org
• Mainnet scheduled for Q4 2026, exact date will be posted on Discord
• Founder fund provides rewards for best videos, posts, and miners (limit 1 000 ZMR)

Issues/complaints

• Mining security — user cryptomaxsun warned about the danger of using the provided commands on Windows without verifying binaries and noted the existence of mirrors after a GitLab outage
• Need for verification — developers stress the importance of checking code signatures and recommend visiting the official GitLab repository (https://gitlab.com/zecreno) and site https://zecreno.org/mine

Overall tone

Neutral‑positive — the community is actively discussing the transition from testnet to mainnet, there is interest in contests and bonuses, but warnings about potential security risks when installing tools independently are also present.

Main topic of new messages: Windows support update — installation via install.ps1 script with signature verification and work on a native Windows miner.

Key news/updates:

• install.ps1 now deploys pre‑built binaries inside WSL and checks their checksums;
• The next update will add verification of the script’s own signature before execution;
• Development of a native Windows miner (plain .exe without WSL) is underway, announcement will be posted in the thread;
• Desktop wallet already has a ready Windows build: https://zecnero.org/wallets
• All files are signed with the key from the first post, source code is available on GitLab: https://gitlab.com/zecnero

Main topic of new messages:

Announcement of testnet update to version v0.2.0 with a network upgrade at block 16 529 and security fixes.

Key news/updates:

• Activation of shielded payments: after the upgrade only coinbase transactions may have transparent outputs; all other transactions use Sapling or Orchard (including change).
• Shielded coinbase requirement: mined coins must be moved to a shielded address before spending.
• Difficulty change: ASERT half‑life reduced from 2 h to 1 h (3600 s) with re‑anchoring to avoid difficulty spikes on transition.
• Orchard proof fix in the wallet; full Orchard support will arrive later, but core rules already work with genesis on mainnet.
• Chain state, balances, and Genesis Miner wall remain unchanged.
• Instructions before block 16 529:
• Update miner (zecnero-miner update).
• Miners in the pool must log in with a Sapling address; after block 16 469 the pool will pay out accumulated balances, and subsequent payouts will go to the registered Sapling address.
• Solo miners keep their nm…‑reward address and must shield the reward before using it.
• Update wallet to version 0.2.2; version 0.2.1 will stop syncing at block 16 529.
• Update daemon zecnerod; a node without the update will stop at block 16 528.
• Security fix: two issues in the randomx-rs-zecnero library (RandomX binding) have been resolved.

Issues/complaints:

No issues or complaints were mentioned in this message.

Overall tone:

Positive/neutral – announcement of an upcoming upgrade and security improvements.
