HashLatch (HLC) is a fair-launch Layer 1 proof-of-work blockchain where GPU miners earn two ways: classic block rewards AND on-chain bounties for solving cryptographic tasks — all enforced trustlessly by the protocol, not by any operator.
No premine. No ICO. No presale. Code is law.

⚡ KEY FACTS
────────────────────────────────────────────────────────
• Algorithm: KawPow (GPU-only, ASIC-resistant)
• Max supply: 21,000,000 HLC
• Block reward: 10 HLC (9.8 miner + 0.2 dev fee = 2%)
• Block time: ~2 minutes
• First halving: block 1,050,000 (~4 years)
• Difficulty: DGW-180, active from block 1 (anti-instamine)
• Premine: NONE — fair launch from block 0

🔐 THE BOUNTY LAYER (what makes HLC different)
────────────────────────────────────────────────────────
Anyone can lock HLC in an on-chain bounty whose payout is gated
by an OP_SHA256 hashlock. Whoever provides a preimage that hashes
to the target releases the funds — directly via the script, with
NO operator custody and NO trusted middleman.
createbounty — lock HLC behind SHA256(target)
listbounties — see all open bounties on chain
solvebounty — spend the hashlock with the preimage (trustless)
commitbounty / revealbounty — optional commit-reveal flow that
protects solvers from mempool front-running
Use cases: password-hash recovery, lost-key recovery, authorized
pentest challenges — a free market for useful cryptographic work.

⛏ HOW TO MINE (solo pool — you mine to YOUR address)
────────────────────────────────────────────────────────
Each miner's block reward is paid by the coinbase directly to the
address in your worker login. The pool never holds your coins.
1) Get an address — open the web wallet at hashlatch.online
2) Download a KawPow miner (T-Rex or GMiner)
3) Point it at the stratum:
t-rex -a kawpow -o stratum+tcp://34.185.173.154:3052 -u YOUR_ADDRESS.rig1 -p x
That's it. Whoever finds the block receives the full reward
(minus the 2% dev fee) straight to their own wallet.
