[ANN][GLAC] Glaciem — Monero fork with original CPU-only PoW (Lattice). True fair launch May 20, 2026.
I've been building a privacy coin called Glaciem (GLAC) since late April. It went live on mainnet on May 20, 2026, 00:00 EDT — pre-announced on r/cpumining the day before:
https://www.reddit.com/r/cpumining/comments/1thwnqd/launching_glaciem_glac_a_monero_fork_with_an/Posting here now to widen the audience. If you mine CPU coins, this is the right crowd to be straight with.
============================
THE SHORT VERSION
============================
Fork of Monero — privacy (RingCT, ring signatures, stealth addresses) inherited unchanged.
Original proof-of-work, Lattice — integer-only, CPU-only. Each hash is a long, serial, latency-bound walk over a ~1 MiB per-nonce scratchpad plus a shared epoch dataset: branchy, memory-hard, no parallelism within a nonce. Rewards wide high-IPC CPU cores and collapses GPU occupancy the way RandomX does. No GPU phase, nothing for an ASIC to target.
~2-minute blocks, no premine, Monero-style emission with tail emission.
Native miner + wallet apps for macOS, Windows, Linux, and Android — the app generates a wallet, syncs, and mines straight to it. No separate wallet daemon, no config files. Runs especially well on Apple Silicon.
============================
TRUE FAIR LAUNCH — verifiable on-chain
============================
The launch instant is consensus-enforced. Every node rejects blocks dated before 00:00 EDT, May 20, 2026 (= 04:00 UTC = unix 1779249600). Block 1 was mined at exactly that timestamp.
Verify on any synced node, two RPC calls:
curl -s -X POST
http://NODE:19081/json_rpc -H 'Content-Type: application/json' \
-d '{"jsonrpc":"2.0","id":"0","method":"get_block_header_by_height","params":{"height":1}}'
→ result.block_header.timestamp == 1779249600
I posted to r/cpumining the day before launch:
https://www.reddit.com/r/cpumining/comments/1thwnqd/launching_glaciem_glac_a_monero_fork_with_an/Anyone who saw that post could start mining at the exact same instant I did. No premine, no presale, no founder allocation. The chain literally rejects pre-launch blocks.
============================
COIN ECONOMICS (same as Monero)
============================
Emission constants identical to Monero's:
MONEY_SUPPLY (uint64_t)(-1) ≈ 18.4M atomic units
EMISSION_SPEED_FACTOR 20 (per minute)
FINAL_SUBSIDY_PER_MINUTE 0.3 GLAC/minute
DIFFICULTY_TARGET_V2 120 seconds
Translation:
block_reward = (MONEY_SUPPLY - already_generated) >> 19
capped below at 0.6 GLAC/block (the tail)
Current block reward: ~35 GLAC, smoothly decreasing.
Main emission ends near ~18.13M GLAC total supply (~30 years out).
After that: tail emission of 0.6 GLAC/block forever — same as Monero. Miners always have a subsidy; effective annual inflation asymptotes to ~0.14% and keeps dropping as a percentage of supply.
No halvings. Smooth curve. No "the security drops off a cliff in 50 years" problem.
============================
CURRENT DISTRIBUTION (transparent)
============================
As of block height 4,324:
Total emitted on-chain: ~151,477 GLAC
My wallets (operator): ~46,539 GLAC = ~30.7% of emitted supply
• main mining wallet: 45,092 GLAC
• pool operating wallet: 349 GLAC
• faucet wallet: 1,098 GLAC
Other early miners: ~104,938 GLAC = ~69.3% of emitted supply
I'm not the only miner — others joined from the r/cpumining post and have been participating since launch. I've run the most consistent hashrate because I have the infra already up.
============================
GROWTH FUND — 25,000 GLAC seeded into the pool
============================
I've seeded the official pool with 25,000 GLAC from my mining wallet as a block-reward bonus. For the next ~10,000 blocks (~2 weeks at 120s target), every block found by the pool pays out ~2.5 GLAC EXTRA on top of the standard ~35 GLAC reward, distributed proportionally to share contribution.
Practical effect: anyone mining through the pool during the next 2 weeks earns ~7% more GLAC per block than the chain reward alone. Bonus comes from my pre-existing holdings, not from anyone else's mining. After the fund empties, payouts return to normal block reward.
Why: this is a small CPU coin and adoption is the main thing it needs. I'd rather seed the network with some of my mining than hoard it.
What I'm keeping:
~21,539 GLAC after the giveback = ~14% of emitted supply
• Dev fund: servers, domains, ongoing development
• Long-term reserve: locked 12 months, no exchange sales, no insider gifts
============================
MINING IT
============================
Downloads (latest release): github.com/hughson/Glaciem/releases/latest
• Mac (universal, 14+) — Glaciem-Miner-macOS.zip
• Windows (x86_64, AVX2) — Glaciem-Miner-Windows.exe
• Linux (x86_64) — Glaciem-Miner-Linux.AppImage
• Android (arm64, API 26+) — Glaciem-Miner-Android.apk
Each miner ships with an embedded GLAC wallet. First launch generates a wallet for you (back up the 25-word seed).
To mine at the official pool: Settings → Pool Mode ON. URL is pre-filled. Min payout 1 GLAC. Pool fee 0%.
To mine solo: Settings → Pool Mode OFF. You'll mine directly against the network and keep 100% of any block you find.
============================
LATTICE GAMES — what GLAC is actually FOR
============================
I'm also building a small VR game catalog where GLAC is the only payment option. Working title: Lattice Games.
First title in development: VR Bowliards — billiards scored bowling-style, on the Valve Steam Frame headset. Premium one-time purchase paid in GLAC, with weekly skill-based leaderboard prizes paid from a sponsorship pool (not pay-to-enter, not gambling — same legal model as Beat Saber community tournaments).
Goal: give GLAC actual product-utility on day one. Earn through mining, spend on games. The pool + miners + chain is the bottom of the stack; the games are the top. No release date yet — when the game is ready it ships.
============================
BEING STRAIGHT WITH YOU
============================
• Hobby project, not an investment. No exchange listing. No fiat market. Don't buy GLAC anywhere claiming to sell it.
• Lattice PoW is original and has not had external cryptographic review. Self-tests against frozen vectors pass on all four platforms (build runs the test on launch and refuses to mine if it fails), but there's tail risk in custom crypto.
• Solo developer with AI tooling. Bus factor of 1. Community help welcome.
• Privacy coin regulatory pressure is real — Monero is delisted from many exchanges. Same forces would apply if GLAC ever gets listed. Mine because CPU-mining a fresh chain on a real PoW is fun, not because you expect a payday.
