# PCASH: playing, finite rewards, offchain balances

PCASH is not issued. The website connects wallets and verifies server-issued game runs. No reward payment or token launch has been executed.

## Playing

Active play starts at 10 points per second. Distance compounds the multiplier by 5% every 250 pixels, capped at 8x. Paused or background time earns no points. Each run lasts at most three active minutes. The server independently replays integer mechanics, checks real elapsed time, immutable checkpoints and the wallet-bound receiving keys. A run-only key signs updates; it cannot Claim or spend funds.

## The 10% reserve

Acquire and hold 10% of the original issued Pump supply. Pump create_v2 does not give a free 10% creator allocation. The actual acquisition quote and financial transactions require owner approval.

A day is one epoch. Schedule 80% of the 10% reserve, keeping the other 20% unallocated. The first 180 days budget half the scheduled amount; each later 180-day era halves the daily cap. Reward = floor(day cap × wallet points / max(40,000,000, total daily points)). A wallet counts at most 100,000 points / 30 active minutes per day, so one wallet receives at most 0.25% of the day cap. Low demand pays less; high demand shares the same cap. Empty days, unused budget and rounding dust never roll into a later payout. These are wallet limits, not proof of unique humans.

For an illustrative one-billion supply, the 10% reserve is 100 million tokens. First-era daily budget is approximately 222,222.222222 PCASH. The actual mint and supply remain unset.

## Claim, Send and Withdraw

Claim adds a fixed daily allocation to a company-held internal PCASH balance.
Internal Send is authorized by the account spending key and conserves balances
in the server ledger. No GPU proof or public token transfer is used. Withdraw
locks units and sends the actual public token to a Solana wallet after customer
and company signatures. Fully signed bytes are recorded before broadcast;
finalization requires two RPC receipts and exact token balance changes.

Client spending and viewing keys are separate from the Solana wallet. An
encrypted, passphrase-protected backup restores account access on another device.
The server must also preserve the custody database and encryption key: a client
backup alone cannot recover a lost company ledger.

This is company custody. The operator sees internal transfers and controls the
reserve. Internal activity stays offchain; Pump trades, reserve acquisition and
wallet withdrawals remain public. It is not Zcash mining or ZK-enforced custody.

## Actual status

PCASH is not issued and this source release has not been deployed. The owner
retains deployment and issuance. No new custom Solana program or GPU worker is
required for the offchain path. Actual issuance, company reserve/signer setup and
a small real withdrawal still precede a claim of live payments.
