docs(10_Wiki): Topic_Business/General/Graphic/Programming을 Topics/ 하위로 이동
최상위 10_Wiki/Topic_*였던 4개 카테고리 폴더를 10_Wiki/Topics/Topic_* 로 재배치. 콘텐츠 변경 없음(순수 폴더 이동) — Topics/ 하위 나머지 폴더는 이미 지난 커밋에서 전부 정리된 상태(잔존 항목은 에이전트 운영 상태 및 사용자가 보존을 요청한 업데이트0615/무제 3.canvas 뿐).

# Play and Earn
|
||||
|
||||
## 매 한 줄
|
||||
> **"매 fun-first, earning은 byproduct"**. 매 2021-2022 P2E 붕괴 (Axie Infinity death spiral) 의 lesson 으로 emerge 한 hybrid model — 매 game 의 핵심은 entertainment, token reward 는 retention sweetener. 매 2026 sustainable Web3 game 의 dominant frame.
|
||||
|
||||
## 매 핵심
|
||||
|
||||
### 매 P2E vs P&E
|
||||
- **P2E (2021)**: 매 earning 이 primary motivation. 매 grinding farm. 매 mercenary players → token dump → economy collapse.
|
||||
- **P&E (2024+)**: 매 fun 이 primary. 매 token 은 long-term retention reward. 매 player base 의 50%+ 가 non-earners 이어도 ok.
|
||||
- **결정적 차이**: 매 game 의 token 없으면 still fun? P&E = yes, P2E = no.
|
||||
|
||||
### 매 economic design pillars
|
||||
- **Sink/Faucet ratio**: 매 token issuance ≤ token burn (장기 deflationary 또는 stable).
|
||||
- **Non-token utility**: 매 cosmetics, social, competitive ranking → 매 non-earner motivation.
|
||||
- **Soulbound progression**: 매 character XP / achievement 는 non-transferable → grinder farm 차단.
|
||||
- **Skill gate**: 매 earning rate 가 player skill 에 비례 → bot resistance.
|
||||
|
||||
### 매 응용
|
||||
1. Pixels (Ronin) — 매 farming-sim 으로 daily active 600k+ 유지 (2025).
|
||||
2. Off the Grid (Avalanche) — 매 Battle royale, AAA quality, optional NFT.
|
||||
3. Illuvium — 매 auto-battler + open world, token earning은 ranked play 에 한정.
|
||||
|
||||
## 💻 패턴
|
||||
|
||||
### Reward emission curve (deflationary)
|
||||
```solidity
|
||||
// SPDX-License-Identifier: MIT
|
||||
pragma solidity ^0.8.24;
|
||||
|
||||
contract PlayAndEarnReward {
|
||||
uint256 public constant INITIAL_DAILY_EMISSION = 100_000 ether;
|
||||
uint256 public constant HALVING_PERIOD = 180 days;
|
||||
uint256 public immutable startTime;
|
||||
|
||||
constructor() { startTime = block.timestamp; }
|
||||
|
||||
function currentDailyEmission() public view returns (uint256) {
|
||||
uint256 halvings = (block.timestamp - startTime) / HALVING_PERIOD;
|
||||
if (halvings >= 10) return 0;
|
||||
return INITIAL_DAILY_EMISSION >> halvings;
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### Skill-gated earning
|
||||
```typescript
|
||||
function earnedTokens(matchResult: MatchResult): number {
|
||||
const base = matchResult.won ? 10 : 2;
|
||||
const skillMultiplier = Math.min(matchResult.mmr / 1500, 3.0);
|
||||
const dailyCapRemaining = getDailyCapRemaining(matchResult.userId);
|
||||
return Math.min(base * skillMultiplier, dailyCapRemaining);
|
||||
}
|
||||
```
|
||||
|
||||
### Soulbound progression
|
||||
```solidity
|
||||
contract SoulboundXP is ERC721 {
|
||||
function _update(address to, uint256 tokenId, address auth)
|
||||
internal override returns (address)
|
||||
{
|
||||
address from = _ownerOf(tokenId);
|
||||
require(from == address(0) || to == address(0), "Soulbound: non-transferable");
|
||||
return super._update(to, tokenId, auth);
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### Sink: cosmetic burn
|
||||
```typescript
|
||||
async function craftCosmetic(userId: string, cosmeticId: string) {
|
||||
const cost = COSMETIC_COSTS[cosmeticId];
|
||||
await burnTokens(userId, cost);
|
||||
await mintCosmetic(userId, cosmeticId);
|
||||
await emitTelemetry({ type: 'sink_burn', amount: cost, source: 'cosmetic' });
|
||||
}
|
||||
```
|
||||
|
||||
### Non-token leaderboard
|
||||
```typescript
|
||||
interface SeasonReward {
|
||||
rank: number;
|
||||
cosmetic: string; // soulbound
|
||||
tokenBonus?: number; // top 10% only
|
||||
title: string; // permanent
|
||||
}
|
||||
```
|
||||
|
||||
### Anti-bot detection
|
||||
```python
|
||||
def is_likely_bot(user_session) -> float:
|
||||
signals = {
|
||||
'click_variance': click_timing_variance(user_session),
|
||||
'movement_entropy': mouse_path_entropy(user_session),
|
||||
'session_regularity': cron_like_score(user_session.history),
|
||||
}
|
||||
return weighted_sigmoid(signals)
|
||||
```
|
||||
|
||||
### Emission throttle (treasury-controlled)
|
||||
```solidity
|
||||
function adjustEmission(uint256 newDaily) external onlyDAO {
|
||||
require(newDaily <= currentDailyEmission() * 110 / 100, "Max +10%/epoch");
|
||||
require(newDaily >= currentDailyEmission() * 90 / 100, "Max -10%/epoch");
|
||||
dailyEmission = newDaily;
|
||||
emit EmissionAdjusted(newDaily, treasuryRunwayDays());
|
||||
}
|
||||
```
|
||||
|
||||
## 매 결정 기준
|
||||
| 상황 | Approach |
|
||||
|---|---|
|
||||
| Casual mobile audience | Token-optional (P&E) |
|
||||
| Hardcore competitive | Skill-gated earning |
|
||||
| F2P with whales | 매 hybrid IAP + token reward |
|
||||
| Pure speculation play | 매 avoid — P2E 함정 |
|
||||
|
||||
**기본값**: 매 P&E + skill-gate + soulbound progression.

||||

- Adjacent: [[LiveOps]]
|
||||
|
||||
## 🤖 LLM 활용
|
||||
**언제**: 매 Web3 game economy design 시 — 매 sustainable token model 이 필요할 때.
|
||||
**언제 X**: 매 traditional F2P (token 없이) — overkill.
|
||||
|
||||
## ❌ 안티패턴
|
||||
- **Pure P2E**: 매 earning 이 fun 의 substitute. 매 mercenary churn → death spiral.
|
||||
- **Unlimited token mint**: 매 inflation. 매 Axie SLP 의 답습.
|
||||
- **Transferable XP**: 매 grinder farm. 매 Ronin botting outbreak.
|
||||
- **No sink**: 매 token velocity 0. 매 price collapse.
|
||||
|
||||
## 🧪 검증 / 중복
|
||||
- Verified (Sky Mavis post-mortem 2023, Ronin Network reports 2024-2025).
|
||||
- 신뢰도 A.
