GCC · reference coin testnet · no monetary value
The coin layer.
Yours to configure.
GCC is the reference cryptocurrency that proves the stack: a working proof-of-work blockchain, real mining payouts and a native wallet — demonstrated on testnet. Supply cap, block time and reward schedule are parameters you set for your own launch.

A note from the developer
Why build a chain at all?
S
Steven
developer · @StevenJTobin
"A proof-of-work chain is the clearest way to show the whole stack actually works: real mining, real blocks, real payouts, and a real wallet that holds the coins. You can read about a crypto stack all day — this is me proving it runs."
Everything here is on testnet, where the coins are deliberately worthless. It's a demonstration, not a coin sale. I'd rather show you a working engine than sell you a promise.
When you buy the stack, the chain becomes yours. Supply cap, block time, reward schedule, halving — they're settings, not promises I'm making. You configure them, you launch, and you take on everything that comes with being an issuer. I built the engine; you decide where it goes.
I'm the developer of the software, not the issuer of any coin. On testnet the coins carry no monetary value. What you do at mainnet — and any value it might carry — is entirely your undertaking.
Launch parameters
Configurable, not fixed.
These are the demo defaults. Supply, emission and distribution are all parameters you set for your own launch — the engineering supports whatever model you choose. Nothing here is a property of the product you can't change.
EXAMPLE DISTRIBUTION · DEMO DEFAULT
70%
15%
8%
- Mining emissions paid block-by-block — you set the curve 70%
- Treasury (optional) on-chain multisig if you choose one 15%
- Pool rewards (optional) bonus payouts you can enable 8%
- Reserve (optional) whatever your model needs 4%
- Founder (optional) vested or zero — your decision 3%
EMISSION CURVE · 20-YEAR SCHEDULE
halves every 4 years
In the demo, block reward starts at 50 GCC and halves every 4 years — but the schedule is a parameter. Set your own starting reward and halving interval.

Build roadmap · 2026
How the stack is progressing.
The development path for the coin layer and its handover tooling. This is a software roadmap, not a token launch timeline — there is no sale, listing or fundraising milestone here.

What the chain demonstrates
Three things you can watch work.
The demo isn't a slide deck — it's the running stack. Here's what the coin layer proves before you commit to a build. All on testnet; coins have no monetary value.
PROOF 01
A working PoW chain
Real blocks, real difficulty
A live proof-of-work blockchain producing blocks on a continuous testnet network — not a simulation. Genesis, difficulty adjustment and block intervals all behave as they would on mainnet.

PROOF 02
Real mining payouts
Pool → block → wallet
The pool finds blocks on the chain and splits the reward to miners' own wallet addresses, end-to-end. You can watch the full path — share accounting, block discovery, payout — in the walkthrough.

PROOF 03
A native wallet
Send, receive, restore
A real, hardened wallet bridged to the same chain — send and receive testnet coins, restore from seed, secured with Argon2id PIN, biometric unlock and FLAG_SECURE. It's field-tested daily, not a mockup.

Wallets
A wallet on every device — in the box.
The stack ships with native wallets across all four major platforms. Same address format, same backup format, same code — re-skinnable in the buyer's brand.

Roadmap
The seed phrase is the wallet. Self-custody, by design.
No recovery server, no "support" team that can reset it — the keys live only on the device. Lose the seed and the testnet coins are gone; copy it and whoever holds it controls the wallet. It's the right security model to inherit: write it down, store it offline, never type it into a website. (Testnet coins carry no monetary value.)
