What It Is
Bitcoin 09 is Bitcoin's old idea with one deliberate swap: Argon2id memory-hard proof of work instead of SHA-256. Normal CPUs can mine it, and ASIC/GPU advantage is intentionally pushed down.
| Bitcoin | Bitcoin 09 | |
|---|---|---|
| Supply cap | 21,000,000 | 21,000,000 |
| Block reward | 50, halves every 210,000 | 50, halves every 210,000 |
| Block time | 10 minutes | 10 minutes |
| Premine | none | none |
| Proof of work | SHA-256d | Argon2id 64 MiB |

Node Notes
Mining only starts when -mine is present. A non-mining node still syncs, relays blocks and transactions, listens on :9009 by default, and can serve its own explorer.
btc09 node -explorer :8009
Wallet balance is calculated from your local synced chain, so a fresh node can show a balance later than the public explorer while it catches up. v0.1.10 and later sync fresh nodes in larger bounded batches and log balance changes as soon as the local chain sees them. Mined coinbase rewards become spendable after 100 blocks.

Markets
There is no official 09C price. Early trading is community OTC only: users can post buy/sell offers in Discord, and completed trades can be referenced as price discovery. Read the markets note before trading.
Third-party Miners
NTMminer is a third-party closed-source binary miner, not the official 09C wallet or node. It only needs your payout address. Do not give any pool miner a seed phrase, private key, wallet file, remote access, or Discord token.

No Promises
09C is worth nothing. Bitcoin was worth nothing in 2009 too, that's the whole idea. No premine, no allocation, no promises. The genesis reward is burned, so every coin that will ever exist gets mined by someone's CPU. Mine it because it's fun and you missed 2009.
