一提到金融,大家最先想到的恐怕就是银行。不管是转账、存款还是贷款,几乎都得通过银行来完成。这就是我们熟悉的中心化金融。银行,就是那个不可或缺的中心。2 i% h) L$ g3 c( W* B4 J
但有没有一种可能,金融活动可以不再依赖银行这样的中间机构?答案就是DeFi,去中心化金融。) Y& w3 f, S" ?; \/ a
在DeFi的世界里,一切金融操作都在区块链上完成,靠的是提前写好的智能合约自动执行。+ R) m* b3 |7 x1 C: P" @1 ?
没有柜台、没有信贷员、甚至没有银行,只有代码和规则。6 F, Y5 X6 O7 {
以借贷为例。) a$ H6 O% U' [6 [
传统世界里,你想向银行贷款,得提交收入证明、抵押房产,签一堆文件,等银行审核通过后才能拿到钱。
3 r v6 V+ e5 H而在DeFi中,这一切变得像在一个全自动的当铺里进行。你不用面对任何人,只需跟程序打交道。
& ]3 T5 ]2 x) e7 X, D& s" I这个当铺能运转,靠的是下面3个核心部件' P* W! w5 z3 Q3 [1 L- A$ p
区块链好比一个公开的账本,记录所有交易,谁都不能篡改。比如在以太坊上记录了你的账户下有1000个以太币,你有这1000个以太币才能进行抵押借贷。- ~% f- x3 B5 ]
然后抵押借钱的关键在于,你抵押的资产到底值多少钱。( L/ x) Z! }0 k$ R {- f, q
传统金融中有专门的人来评估你的房产。在Defi中则依靠Chainlink 预言机,它负责实时汇报外部价格。比如说1个以太币3000美元。/ R( e- N, @* V5 o( z! p0 `
有了区块链和预言机,当铺才知道了你抵押的资产值多少钱。但你能借多少钱,利息多少,钱从哪里来。& A2 f; c" b. F5 L: Y: N# f
这些就是借贷协议层,这里就相当于当铺本体,规定了借贷行为的各种规则, U6 N$ p/ i% g, a* {
典型代表有 Aave 和 Compound。
: B4 C5 t9 \0 `' }: U/ C: o比如我们定义了资金池,所有想赚利息的人,把钱存进来的,形成了一个大资金池。这些钱就可以拿去借给别人。
: u$ a' h. a2 e# N4 a6 ~你想借钱,就从池子里拿。你存钱进去,就相当于当了债主,能收到别人借钱的利息。
/ d, v5 I" P% I' g你想借100块钱,那你必须抵押价值至少150块的东西,防止你借钱跑了。
7 n5 }/ |, {; C: k0 s, |0 p万一你抵押的东西价格暴跌,只值120块了,机器人店员不会打电话催你,会直接把你抵押的东西卖掉,先把100块本金拿回来,保护资金池的安全。这个过程就叫清算,对你来说很无情,但对存钱的人来说很安全。
. u2 P0 p4 j/ g' `- [这些零零散散的借贷协议,保证了当铺的运作。; V1 U3 l: x2 j' b7 F: N5 i3 Q6 G
DeFi不是虚无的概念,它正在重构我们对金融的认知。当然,它仍处于早期阶段,高收益往往高风险,特别是智能合约漏洞和资产波动可能导致资产直接归零。" y. @# ?4 i9 w+ c) c4 Y2 B
