DeFi 若保持目前的发展态势会对 BTC 的安全造成较大冲击. 1 提高手续费方案 由于手续费的目标提升水平在百倍级别，可能会赶走更多用户，可操作性极低。提高区块大小让每个区块支持更多交易也可以变相提高矿工的手续费收入，不过关于这个方案比特币社区内已经有过争论，BCH 的分叉和后续发展显示多数人仍是“原教旨主义”者，并不支持 BTC 规则出现较大的改动，且 BTC 面对的核心问题并不是拥堵而是交易不足。 2 将 Bitcoin 升级至支持智能合约，建立原生 DeFi 生态，从而将交易留在 BTC 本链上 第二种方案是将 Bitcoin 升级至支持智能合约，建立原生 DeFi 生态，从而将交易留在 BTC 本链上。关于 Bitcoin 与智能合约的讨论和实践已经是一个老话题了，即便在 Ethereum 上已经有非常丰富的 DeFi 生态，部分观点仍坚持 Bitcoin 应主动引入 DeFi。 原因有三，首先 BTC 作为加密市场中最重要的资产占据六成以上的份额，没有或仅低度参与 DeFi 是不可想象的，而 BTC 也需要成为一种创造收益的主动型资产；其次，Bitcoin 具备最广泛的共识、最健壮的网络和最高级别的安全性，(如果可以的话）在 Bitcoin 部署 DeFi 将是理想状态；最后，Bitcoin 上的智能合约存在可能性，通过脚本语言、闪电网络、侧链或联合挖矿链等古怪但不失创新的独特方法，使 Bitcoin 也可以支持智能合约逻辑。 但实际上，虽然目前通过资产网关将 BTC 引入至 Ethereum 的规模仍较低且方式略显中心化，但迁移 BTC 的速度在快速增长，BTC 已经参与到开放网络的金融和货币市场中，而且有越来越多的 DeFi 项目在从应用层解决这个问题。 Bitcoin 作为结算层在性能上还远不能支持庞大的 DeFi 交易需求。最后，是在不改动 Bitcoin 核心协议的前提下支持智能合约的可行性的问题，相关的设想可以追溯到五年前为 BTC 设计扩容方案时期，而直至今天未出现一个可行方案。目前的尝试无法在不制造共识分裂的前提下支撑与主链安全等级一致的逻辑复杂的智能合约。而对于将 Bitcoin 整体硬分叉成为智能合约兼容的新链的可能性可以忽略不计。对比在 Bitcoin 上开发 DeFi 的成本和推进速度，BTC 继续作为被动资产参与 DeFi 生态可能性更高。 3 提高 BTC 总量相对为最合理的方案 第三，提高 BTC 总量相对为最合理的方案。关于减半是否会危害网络安全问题已经是一个古老的议题，但 DeFi 让 BTC 的使用场景脱离了之前讨论发生是的语境。通过 DeFi，BTC 将以各种形态脱离 Bitcoin 作为价值符号流通在其他便宜好用的 Bitcoin 的 Layer2 中，而最可能维持网络安全的是提升 BTC 总量的方案，将 BTC 的货币政策由通缩改为温和的线性通胀，以覆盖基本的网络安全成本，这个观点同时被普林斯顿大学的三位学者讨论过。他们提出，如果没有固定的区块奖励，比特币挖矿出块的收益完全基于手续费时，收益的方差将变大，这将不可避免的激励自私挖矿行为的出现，导致比特币网络陷入混乱。而他们也认为温和通胀让挖矿收益变得相对可预期或许是最好的解决方案。 所以我们认为当手续费将必然成为 BTC 矿工收入的主要来源时，DeFi 若保持目前的发展态势会对 BTC 的安全造成较大冲击，因为 DeFi 使 Ethereum 成为 BTC 的交易层从而降低了BTC的网络手续费。为保护 BTC 网络安全性会出现这三种情况：BTC 提升手续费、BTC 链上支持 DeFi 和 BTC 提高总量，而最终温和通胀的方案会被采用。 # 本帖 steem 首发 [ DeFi 对 BTC 的安全造成较大冲击 ](https://steemit.com/@sunyuchen/20201219chong) # 最近新帖 1.
