purpose.
Orange is an independent, CPU-mined proof-of-work blockchain. OAG is its native coin. Its appeal is a deliberately limited monetary system that you can run, inspect and participate in.
This is our interpretation of the design, not a promise about its future price. Technical facts below are based on the upstream project and specification, reviewed October 10, 2026.
The basic ingredients
| Consensus | RandomX proof of work; CPU-oriented mining. |
|---|---|
| Ledger | UTXO accounting: transactions spend existing outputs and create new ones. |
| Signatures | BIP340 Schnorr on secp256k1; BLAKE3 tagged hashes. |
| Block target | 60 seconds, adjusted by difficulty. Actual intervals vary. |
| Issuance | 10 OAG per block, no halvings, capped at 1 billion OAG—roughly 190 years at target cadence. |
| Distribution | Upstream specifies no premine, ICO or developer reward; the genesis reward is burned. |
Why we find it interesting
Participation starts with a CPU
RandomX makes ordinary general-purpose processors relevant to mining. That lowers one kind of entry barrier. It does not make electricity free, guarantee profitability, or prevent hashpower from concentrating.
A small set of rules
Orange deliberately leaves out a general scripting language and virtual machine. There is less machinery to understand than in a general-purpose smart-contract platform. That is an appealing engineering constraint, not proof that the implementation is secure.
Distribution over generations
Flat issuance avoids periodic halving events. As supply grows, the same annual issuance becomes a smaller percentage of the total. The cap is distant; most of the supply has yet to be mined.
Keys can also be a voice
Version-0 addresses encode a public key. OAG’s separate message-signing scheme lets someone prove control of that key without sending coins. Our forum uses this for login. A signature proves address control, not a real-world identity or a balance.
What it gives up
The ledger is transparent. Address activity and balances can be linked, including to forum posts made under the same address. There is no general smart-contract platform, and high throughput is not a stated goal.
A small network also has real limits: concentrated mining, thin participation, immature tooling, changing software, and uncertain liquidity. Faster blocks are not the same thing as stronger settlement. None of these design choices guarantees demand or a market price.
Distinctive is not unprecedented
CPU mining, UTXOs and Schnorr signatures exist elsewhere. The interesting part is the particular combination, the restraint, and the opportunity to understand a young network from the ground up.
