[ANN][LTA] Lattica - Post-Quantum PoW | ML-DSA-44 | SHA3-256d GPU | Fair Launch

[lattica-core]

⬡ Lattica (LTA)
A post-quantum cryptocurrency built on the Bitcoin Core architecture
GitHub · lattica.org · Telegram

When a large enough quantum computer exists, Shor's algorithm breaks the ECDSA signatures that protect every Bitcoin and Ethereum coin. Lattica keeps Bitcoin Core's battle-tested design — UTXO ledger, Script, full-node validation, P2P network, HD wallet — and replaces the cryptography that won't survive:

• Quantum-resistant signatures — every coin is locked with ML-DSA-44 (CRYSTALS-Dilithium, NIST FIPS 204). No ECDSA, no secp256k1 anywhere in the tree.
• Quantum-resistant network — the encrypted v2 P2P transport uses ML-KEM-768 (CRYSTALS-Kyber, FIPS 203) key agreement, enabled by default. The wire is quantum-safe too, not just the coins.
• SHA-3 everywhere — consensus hashing is SHA3-256 (Keccak, FIPS 202), not double-SHA256.
• Simple, GPU-friendly proof-of-work — SHA3-256d over a standard 80-byte header with Bitcoin's 2016-block difficulty retarget. A portable OpenCL miner ships in-tree (NVIDIA / AMD / Intel).
• Fair launch — no premine, no ICO, no dev tax, no masternodes. The genesis output is provably unspendable (OP_RETURN). Every coin must be mined.

— Specifications —

— Downloads (v0.1.0) —

• Windows installer:
• Windows portable: lattica-0.1.0-win64.zip
• Linux x86_64: lattica-0.1.0-x86_64-linux-gnu.tar.gz
• Source + build docs: github.com/lattica-core/lattica

Every archive ships the GUI wallet (lattica-qt), node daemon (latticad), CLI, offline tools and the GPU miner (lattica-miner). Verify against SHA256SUMS.

— Run a node & mine —

Code:

# start a full node (Linux)
./latticad -daemon

# mine to the node with your GPU
./lattica-miner        # see the README for RPC flags

The network is bootstrapped by DNS seeds (seed.lattica.org / .uk / .us) with nodes in the US, UK and Asia.

Post-quantum from genesis. Fair launch. No premine.
Bring a GPU.

What's going on with the website ?? Did you forgot to create ?
And are you the same dev as the flowcoin flc or whatever symbol was ??

That "Block time: 10 minutes (2016-block retarget)" is bad, if someone with a big hash leave the chain, your chain will get stuck at high diff for 2016 blocks, you guys never learn.

[lattica-core]

Thanks for the questions.

Website — it's up now: https://lattica.org

Difficulty — fair point in general, and hit-and-run diff swings are exactly what
kill small coins. The reason 2016-block retarget is workable here specifically:
SHA3-256d has no rentable hashrate market and no idle ASIC farms — you can't spin
up a huge amount of SHA3-256d hash and dump it on the chain the way you can with
SHA-256/scrypt on NiceHash. So the "big miner joins then leaves" scenario is far
less likely than on a rentable algo. It's on the radar though — the retarget is
a one-file swap to a per-block DAA (ASERT/LWMA) if real hashrate volatility ever
shows up. I'd just rather not add timestamp-manipulation surface preemptively.

On the dev question — Lattica stands on its own code. It's all open
(github.com/lattica-core/lattica), fair launch, no premine, genesis output is a
provably-unspendable OP_RETURN. Judge it on that. Happy to answer anything
technical.

GPU miner + full node are in the v0.1.0 release. Bring a card.

I'm experiencing a blockchain synchronization issue. My node syncs the headers, but the block height stays at 0, so I can't complete the sync. I'm not sure how to resolve it. Could you please help?

[lattica-core]

Your node has the headers but lost its peers (getblocktemplate says "not
connected" = 0 connections), so it has nothing to download block bodies from.
The chain itself is fine — the seeds are fully synced and serving blocks. You
just need a stable peer. Add the seed nodes explicitly:

  ./lattica-cli addnode 52.2.229.188 add
  ./lattica-cli addnode 51.24.93.148 add
  ./lattica-cli addnode 13.124.192.251 add

(or put them in ~/.lattica/lattica.conf as
  addnode=52.2.229.188
  addnode=51.24.93.148
  addnode=13.124.192.251
and restart latticad).

Then:
  ./lattica-cli getpeerinfo    # you should see the seeds connected
  ./lattica-cli getblockcount  # will climb from 0 up to the tip

Give it a minute to download the blocks. IMPORTANT: don't run the miner until
"blocks" has caught up to the network height — mining on top of block 0 would
build a fork off genesis that gets orphaned. Sync first, then mine.

(The "tor ... 127.0.0.1:9051 Connection refused" lines are harmless — you don't
have Tor running. Add listenonion=0 to silence them.)

Next time you clone another coin, don't forget to rename the coin name everywhere in the code. I found references like `{'F','l','o','w','C','o','i','n',...}` still present.

I'm almost 100% sure you're the same developer behind FlowCoin (FLC). You posted multiple FlowCoin threads on Bitcointalk, and all of them ended up being deleted. Now it looks like you're trying again with Lattica.

Yep — that output means your miner is finding blocks, so you're good. 👍

Lattica is solo mining, so there's no separate "pool payout" — every block you mine pays its full reward straight to the address in your own wallet via the coinbase transaction. Your payout history is your wallet's receive history.

How to check:

GUI (lattica-qt): open the Transactions tab — each mined block shows up as a reward. Freshly mined coins are immature until 100 confirmations (~a couple hours), then they become spendable. The Overview tab splits your balance into Available and Immature.
CLI:

lattica-cli getbalances               # mine.trusted (spendable) + mine.immature
lattica-cli listtransactions "*" 50   # each reward, category "immature" / "generate"
If Immature is growing but Available is still 0, that's normal — just wait for the 100-conf maturity. If both stay 0 while mining, your blocks likely aren't being accepted — check lattica-cli getpeerinfo shows peers, and I'll help debug.

📈 OTC is live — the first LTA price offers are up in #otc.

Early asks range from ~$0.05 to ~$1 per LTA. A wide spread like that is normal on day one of any market — a real price only forms once buyers and sellers actually trade. Lattica isn't on an exchange yet, so it's pure peer-to-peer.

Want in? Head to #otc, read the pinned safety rules, and start small. The project sets no price — it's whatever you and a counterparty agree on.Network Update — Day 4

Mainnet steady, growth is organic since launch:

• Network hashrate: ~160 GH/s (120-block avg), ~100 GH/s on the last 10 blocks
• Nodes: 110+ connected, IPv4 + IPv6
