About Bitcoin
比特币是世界上首个去中心化加密货币,由化名为“中本聪”(Satoshi Nakamoto)的人物于 2009 年创立。它支持点对点的电子现金交易,无需银行或政府等中介机构,运行在由工作量证明(PoW)挖矿和 SHA-256 加密算法保护的区块链上。
凭借 2100 万枚的固定供应上限和每四年减少矿工奖励的程序化“减半”机制,比特币被设计为一种通缩型数字资产,常被称为“数字黄金”。其价值源于在没有受信任中介的情况下解决了“双重支付”问题,创造了首个真正稀缺、具有抗审查性且无需许可即可访问的数字资产,任何政府、公司或个人都无法控制。
比特币作为一个去中心化的点对点网络运行,交易被记录在一个称为区块链的公共账本上,该账本分布在全球数千台计算机上。交易被打包成区块,通过“挖矿”大约每 10 分钟添加一次,在此过程中,专用计算机竞争解决复杂的数学难题。
比特币已通过多种途径实现了主流采用。2024 年 1 月,美国证券交易委员会(SEC)批准了 11 只比特币现货 ETF,向传统金融参与者开放了比特币投资;像 Strategy(前身为 MicroStrategy)这样的公司正在将比特币作为资金储备资产,以抵御货币贬值,并为 MSTR 持有者提供放大的比特币敞口。
随着创新的不断涌现,比特币生态系统持续发展。例如 2023 年 1 月出现的 Ordinals,实现了直接在比特币上运行类似 NFT 的功能;以及 BRC-20 代币,这是一种利用 Ordinals 铭文创建同质化代币的实验性标准。BTCFi(比特币金融)代表了超越比特币传统角色的新兴金融应用,诸如 Babylon 之类的协议允许比特币持有者通过质押 BTC 来保护权益证明(PoS)链的安全。
