# 認識風險，保護資產

- [區塊鏈風險總覽](https://www.0x1.academy/ren-shi-feng-xian-bao-hu-zi-chan/blockchain-security.md): 「區塊鏈很安全。」
- [51% 攻擊](https://www.0x1.academy/ren-shi-feng-xian-bao-hu-zi-chan/51-attack.md): 想像一個 100 人的村莊在投票。
- [女巫攻擊](https://www.0x1.academy/ren-shi-feng-xian-bao-hu-zi-chan/sybil-attack.md): 想像一個小鎮要投票決定蓋公園還是停車場。
- [雙花攻擊](https://www.0x1.academy/ren-shi-feng-xian-bao-hu-zi-chan/double-spending.md): 想像你有一張 1000 元的鈔票。
- [量子攻擊](https://www.0x1.academy/ren-shi-feng-xian-bao-hu-zi-chan/quantum.md): 量子攻擊顧名思義就是關於量子電腦的出現對區塊鏈造成的影響。因量子電腦跟一般電腦相比運算速度極快，一旦出現即會贏過目前大多數礦工電腦有限的算力，可以立刻以算力的優勢掌控任何以工作量證明為基礎的區塊鏈網絡，迅速驗證區塊而成為最後合法的最長鏈。
- [流量攻擊（DDoS）](https://www.0x1.academy/ren-shi-feng-xian-bao-hu-zi-chan/ddos.md): 想像一條只有兩線道的公路。
- [無礦風險](https://www.0x1.academy/ren-shi-feng-xian-bao-hu-zi-chan/zero-block-reward.md): 無礦風險指的是在區塊鏈中，因挖礦不再有新的代幣回饋給礦工，造成礦工沒有繼續挖礦的動機。以比特幣區塊鏈來說，比特幣約在西元2140年會被全數發放完，不會再有新的比特幣透過挖礦生成。到那時，礦工唯一的獎勵就只能依賴交易發出者提供的交易手續費來維持區塊鏈網絡。
- [人為風險](https://www.0x1.academy/ren-shi-feng-xian-bao-hu-zi-chan/human-error.md): 人為風險是指與區塊鏈架構設計無關，單純在『應用』區塊鏈時的疏失，如智能合約工程師開發上的失誤。
- [如何保護資產](https://www.0x1.academy/ren-shi-feng-xian-bao-hu-zi-chan/asset-protection.md)
- [授權管理（Revoke）](https://www.0x1.academy/ren-shi-feng-xian-bao-hu-zi-chan/token-approval.md)
- [常見詐騙手法](https://www.0x1.academy/ren-shi-feng-xian-bao-hu-zi-chan/scams.md): 在區塊鏈的世界裡，有一句話：
- [假錢包 APP](https://www.0x1.academy/ren-shi-feng-xian-bao-hu-zi-chan/scams/fake-wallet.md): 你在 App Store 搜尋「MetaMask」。
- [釣魚網站](https://www.0x1.academy/ren-shi-feng-xian-bao-hu-zi-chan/scams/phishing.md): 你收到一封 Email，看起來是 Coinbase 發的。
- [空投詐騙](https://www.0x1.academy/ren-shi-feng-xian-bao-hu-zi-chan/scams/airdrop-scam.md): 你的錢包裡突然多了一個奇怪的代幣。
- [龐氏騙局](https://www.0x1.academy/ren-shi-feng-xian-bao-hu-zi-chan/scams/ponzi.md): 「保證每月 10% 收益。」
