对leaf的一些分析: 比特币上以leaf开发的协议和eth上的defi协议仍然有些不同,但希望能透过以下说的缺陷和怀疑,再反观leaf的创新性,会更加理性: 1·eth上的defi,当借款人抵押,并借出,如果抵押物的价格下跌到清算线,会立即清算。对于债主而言,他借出去是比较安全的。 但是btcfi的leaf协议不同,即使借款人抵押了110%~150%于借出的axbt(每axbt等于1聪的价值绑定),清算线是不存在的,也就是btc抵押在里面下跌50%下跌99%归零还是上涨,都不会产生清算。leaf协议下的清算机制是:由借款者限定一个“时间线”,譬如100天之后,在这100天内无论比特币插针还是拔网线,还是暴涨,总之最后那一天只要比特币涨回去了,只要在最后一秒前把axbt给回系统,系统就会把抵押物btc返还给借款人。如果比特币暴跌50%,借款人发现手里的axbt的价值还大于比特币的价格,借款人就可以不还钱。他就可以在超过100天之后,拒绝还款。这时候市场上的债主,就可以开始“狩猎”了,债主在超过“时间锁”的100天之后,随时随地都可以去市场购买等同于当初借给借款人的axbt,等同数量。然后塞回给系统,系统再把暴跌了50%的比特币转给债主。 注意,leaf的债主并不是一个独立的人借给你的,leaf的债主是一群人,是一群市场上主动买入leaf和axbt代币各一半的,看好leaf协议的投资人,他们提供了流动性。借款人去借钱,系统收取一些税费奖励这些提供流动性的人;借款人借的钱,就是这些“提供双边流动性的债主”的钱(技术其实不是双边,但功能效果一样)。 刚刚讲了btc暴跌,下面讲下btc暴涨和不涨。如果100天之后,借款人忘记了时间,债主会在临近时分就开始“狩猎盯盘了”,哪个债主看到一笔超过“时间锁”的单子公开到市场的第一秒,他就可以将这些btc还保留有原价值或者暴涨的价值,以当初借款人借走的多少axbt的数量,以等同的axbt归还系统,就可以取回这笔btc,获得超额收益。 注意:债主之间谁gas高,谁第一个抢到,而且如果借款人即使超过100天,只要他比债主的gas费还高,他依然能有资格去还axbt赎回btc。 在这里会发现,借款人和债主之间是一种零和博弈的对手盘。双方甚至等于在针对“一个时间期限后”比特币是长还是跌,是多还是空的期权对赌。如果btc未来下跌,借款人开的“借款合约”不赎回,盈利,债主承担损失(因为借款人跑路了一分钱拿不回来,现在债主偿还axbt,至少还能回本一些,如果btc跌的太多了,债主也干脆不赎回了,不然再次增加亏钱,但幸好比特币整体的插针回复,和长期的回升力,这个导致崩盘的情况概率很小);如果btc未来上涨,债主们就期待借款人忘记还款期限,立刻“狩猎”这块肥肉,但是借款人如果普遍都很小心,那么债主们也就什么收益都没有,依然只有整个协议的流动性和微博利息。 2·稳定币并不如btc和axbt的流动性池子。 目前最大的问题是,整个协议号称一个axbt等于1聪,保证了一个比特币能兑换出的axbt的铆钉稳定性。但是由于axbt需要用户们通过唯一的交易对,现在市场上买入leaf代币,而leaf代币是在市场上波动的,然后再买入axbt。 因此axbt和比特币的一聪之间的汇率,也会因为目前leaf和axbt的池子比较浅,而产生波动。譬如axbt现在跌到了只能兑换0.8聪,这时候怎么办? 市场的借款人和债主都会自动去修复差价,譬如一个借款人本来要还1000axbt,他由于借到了axbt立刻买入了leaf,手上没有axbt,本来100天后到期要花1000聪的价格买回1000axbt还款,才能取回btc抵押物(约等于1100聪~1500聪的价值,时间锁的期限如果是200天更久,抵押物的价值系统就要求抵押的越高),但他现在看到只需要800聪就能还款,他会立刻去抄底这些axbt修复价差。 而市场上的债主们,同理,市场上如果一直停留着一些借款人超过时间锁的btc抵押物,而且长期没有一个债主愿意去支付axbt赎回,这证明现在现在市场很差,如果债主赎回这些不值钱暴跌50%的btc(比如:借款人之前9万美金抵押物,借走了6万美金的axbt的钱,债主支付了6万美金的axbt,现在比特币跌了50%,抵押物只有4.5万美金,但是借款人肯定沾沾自喜拒绝还钱,超过时间线,但一个个体的“狩猎”债主 任然要偿还给系统6万美金等值的axbt,注意借款人跑路的时候,不是这一个债主承担,是所有提供双边流动性池子的人共同承担,axbt的价格略微下跌,此时市场上这个违约的btc抵押物,借款人不要了,就看有没有个体债主愿意代替借款人偿还等数量的axbt给系统,也就是注入资金买入leaf,再兑换为axbt,这对系统而言就是修复了axbt的下跌,略微回升到1聪的平衡点。 但是这里注意:一个狩猎这些违约借款合同的人,他会计算:剩下4.5万美金价值的btc,我却要还款6万美金价值的axbt?他倒亏1.5万元?所以他大概率不会去还款。 而这时候当axbt下跌到0.8,他只需要还款5万元,如果axbt下跌到0.5他只需要花3万美金就可以买入之前6万美金等同数量的axbt,环入,就可以拿走4.5万美金价值的btc,中间利润为1.5万美金。 以上就是axbt目前价格暴跌如何修复,至少可以肯定的是,这个不会像luna那样螺旋暴跌。) 但是即使axbt的价格可以价格行为去修复,但是这只是弥补的方法,整个leaf协议最大的问题,依然是只有leaf一个入口,才能买入axbt,leaf的池子特别小,即使未来会很大,但是leaf毕竟还是不如一个类似usdc母公司提供法币和usdc1:1兑换的稳定的锚,而官方最好的方法就是提供btc和axbt的交易对。但是现在技术没法实现,因为现在只是质押btc,获得一部分axbt,但是axbt和btc之间的流动性池子并没有出现,而且这个技术障碍还需要未来去攻克。因为比特币原链很难识别crc协议,产生比特币和axbt之间的原生交换,或许未来leaf团队能攻克,但也需要很久譬如数年。 leaf团队,现在退而求其次,不能以btc和axbt进行锚定。我自己发行一个wusd的稳定币行不行?wusd被人们承认,是1:1锚定usdt的。而这里的风险在于,wusd能让circle这样的合规母公司,通过代币合约安全审查,然后发行吗?这也是很以后的事情。里面是否有漏洞?需要更严苛的审查。但是,至少类似我们这些早期使用者,愿意去支持,以1美金等于1wusd的方式去相信,或以()链下市场)usdt和wusd的池子,在它的链下客户端中兑换,会产生一个池子,再由wusd和axbt的(聪单位)间形成强劲有力的刚性兑付的锚定。 所以目前整个leaf的协议,最核心的问题就是刚性兑付,导致的1axbt能否稳定=比特币1聪,牢牢的锚定。这里是用户们安全储值,和保证axbt不会只有单单一个leaf通道进出兑换造成的,暴涨暴跌的波动性。 最疑虑的说完。我们再说说好处,再最后说回让人欣喜的愿景: 1·好处: a·无论是runes的烷jin协议,这个协议即使是美国安全审计合规了,他们的defi也不是在btc的原链上的,是其它链下的池子,所以根本就不能说是btc的btcfi。还是第三方的。 b·eth的defi,有一个痛点,插针!!!如果插针30%,你的抵押物就已经爆仓了!对于借款人而言,当然开心的要死。对于借款人而言,插针立刻回收白白损失了。30%的亏损。而btc的时间线,你自己借款人自己写deadline,时间线,并且写了之后之前的任何一天,你都可以还款,而且不管btc如何插针,只要修复回去了,你就可以高高兴兴的赎回btc,根本就没有插针风险。所以对于借款人而言,这是很开心的一件事。 c·闪电网络和leaf协议不构成竞争,闪电网络是支付速度,处理速度,和leaf反而是互补性的。所以没有竞争。 d·之前的btc的defi是怎么做的?是类似在bsc链eth链发行映射一个假的wbtc进行,而管理wbtc的是一个第三方的机构,是人的机构!这是多么不安全的一个行为啊!!! 对于一个btc原生原教旨主义者,就和沙丘里的革命军一样,我的btc质押,怎么能掌握在帝皇的手里呢?所以btc的质押如果能就在比特币链上,非常的安全!就好了!所以leaf协议达到了,划时代的处理! 我甚至可以“贬低”的说,虽然axbt肯定不会像luna一样死亡螺旋,但是就算在比特币开始一次新概念的创新,再死亡一次,又如何?就没有高估值了?这段话可以省略。 回到客观的话来说:leaf是目前整个比特币,唯一提供了比特币的持有者(超级大户和权贵们),不用离开比特币链,把比特币质押在比特币原链上,不用交给别的人别的机构(会跑路),只靠比特币上的时间锁,就可以直接在原链上释放流动性,将静态储值,释放为比特币愿链上的动态流动性,具有套利的行为。我认为这个基础设施的出现, 先不管锚定的axbt的安全性,未来一定会出现axbt和更多比特币原生币中的交易对: axbt/ordi axbt/runes axbt/bitmap ... .. 当比特币的defi基座从0到1出现,横向扩充更多比特币的原生交易对的流动性世界,就会出现。 注意:axbt和btc交易对的技术攻克很难,而axbt和ordi,runes,bitmap这些同为xrc-20的协议,同为 meta-protocol 资产,技术上相对可行,难度降低很多。就看未来leaf协议方如何攻克。 而注意,如果未来leaf和bitmap ordi之间的交易对,无法原链上攻克,只能链下撮合手段,第三方解决,这也会一定程度稀释leaf协议所谓的原生btc原链btcfi的叙事浓度。 最后说回整个协议,一开始的初心,也是最让人希望的愿景: 只在比特币原链上,发生比特币的金融行为,没有以太坊,比特币的wusd稳定币,比特币的静态储存质押,并释放出axbt的动态流动性在比特币链的未来更多池子内穿梭。 目前crc-20协议最牛逼的就是实现了借款人质押btc,在btc上原生的聪,类似染色的聪变为axbt(但不是染色聪说是),再释放一部分axbt给回借款人。 有人说为何我持有btc,就可以交易,我还要一个axbt来提供流动性? 因为btc你现在只能卖出,或者买入,然后质押给第三方,获得利息,btc你安安静静地持有就没有任何收益!就是一块死饼!但是axbt,btc还是在链上时间锁锁着的,你axbt就在链上,在没有其他交易对出现的当下最初期,你至少可以拿到axbt和leaf做流动性池子,获得稳稳的微弱利息和报酬。这也相当于btc现在持有你没有卖出,仍然在为你身产生收益。 总之,比特币第一次产生了质押和借贷,而借贷让你不用卖出btc,随时能够赎回的前提下,还稳稳的参与投机性、流动性的生息收益。 ordinals没有,stamp没有(src-20),atomicals没有(arc-20),cbrc-20没有,runes没有,bitmap没有。 这是比特币第一个原生defi的资产协议。 投能够接受归零的的钱,然后忘记他,很可能归零,也可能...

GM Frens. First CRC20 stablecoin on Bitcoin is a bigger step than it looks. Most Bitcoin stablecoins still rely on sidechains or federations. @theprecop is trying to keep the state and enforcement closer to L1 using covenants under CRC-20. If the stablecoin pool works, it means they’re testing collateralized debt without moving everything off the base layer. LEAF already handled basic tokens. An AMM and now a stablecoin pool is the next real test. Still early and liquidity will stay thin, but this is one of the few attempts actually building financial primitives directly on Bitcoin instead of waiting for a soft fork. Worth watching how the first pool holds up. @laz1m0v @tap3leaf

WUSD 是 PRECOP / CRC-20 协议在比特币 L1 上的稳定币(stablecoin)代币。 @leloupump 它属于 CRC-20 Mint / Burn Standard,和 AXBT 组成了 AMM 流动性池(AXBT-WUSD)。PRECOPSCAN 是这个协议的链上状态观察工具,用来展示基于 Taproot MAST 契约(covenant)的池子、金库等状态。 关键信息: • 协议背景:这是 PRECOP(Predictive Covenant Oracle Protocol)+ CRC-20 体系。它在比特币主网用 Taproot + MAST + Simplicity 实现类 DeFi 功能(CDP 金库、恒定乘积 AMM 等),不需要软分叉,每个金库/池子都是独立的 Taproot UTXO。 • AXBT:BTC 抵押的债务代币(通过 CDP 金库铸造,锁 BTC 借出 AXBT)。 • WUSD:被明确称为该体系下的稳定币(“First CRC20 stablecoin on Bitcoin” / “stablecoin in development”)。近期(约 2026 年 10 月)有相关实验,包括无预言机荷兰拍卖(oracle-free Dutch auction)和 AXBT-WUSD 池子上线。 @laz1m0v 图中显示的现货价格(1 AXBT ≈ 0.21138 WUSD)、池子流动性(约 18k WUSD)以及契约结构(Stateful AMM Pool Covenant、Dual-Horner Monotonic 等)都符合这个定位。 注意:这和以太坊等链上常见的 Worldwide USD(WUSD) 法币抵押稳定币不是同一个东西。截图里的 WUSD 是比特币原生 CRC-20 代币,依托 PRECOP 的契约机制。 相关资料主要来自 crc.garden、PRECOP 相关 GitHub/README,以及协议开发者(@laz1m0v、@theprecop 等)的公开帖子。这个生态还比较早期,具体稳定机制(合成、抵押、拍卖清算等细节)以官方文档和链上状态为准

LEAF just posted a short thread calling the whole thing highly experimental, running 32 bytes at a time, and sitting directly on Bitcoin. That’s pretty honest. Most projects in this space overpromise. @leaf_btc is openly saying the system is still experimental while showing it’s actually executing on L1. The 32-byte constraint is interesting because it forces everything through small, verifiable pieces instead of big smart contract calls. It limits what you can do in one step, but it also means the state changes stay tightly bound to Bitcoin’s existing rules. They already went from basic token minting to AMMs and now a stablecoin pool. Seeing them keep emphasizing that it’s experimental while shipping these pieces is better than the usual “this is the future of finance” posts. Still early, liquidity is thin, and a lot can break, but @tap3leaf and the Precop team are building actual financial primitives on Bitcoin instead of waiting for soft forks or moving everything to a sidechain. Curious to see how the first stablecoin pool behaves once people actually start using it. @theprecop @laz1m0v

**Why this actually breaks the previous model** Bitcoin never had a clean way to do non-custodial debt and AMM logic on L1. You either: - moved to an account-based chain, - accepted a sidechain / federation, - or waited for a soft-fork that may never activate. PRECOP doesn’t do any of that. Every vault and every pool is a single Taproot UTXO. The address *is* the state. There is no shared storage. There is no global balance sheet. If vault A is insolvent, vault B is physically unreachable. That’s not an economic incentive. That’s topology. The classic hole on Bitcoin has always been the signer. Whoever holds the key that can spend the UTXO can usually redirect the outputs. OP_CTV, OP_TXHASH, and BIP-443 exist because of this. PRECOP closes it without them. At vault creation the borrower generates an ephemeral key, pre-signs the exact residual output under `SIGHASH_SINGLE | ANYONECANPAY`, then destroys the private key. The liquidator never sees it. If they try to change the residual address or even shave 1 sat, Bitcoin Core rejects the transaction on L1 with `SCRIPT_ERR_SCHNORR_SIG`. The sats never move. Tokens are enforced separately. The L2 indexer reconstructs the expected outputs from the witness stack. Any mismatch (wrong edict count, wrong amounts, diagonal shift, desynced CRC20) is permanently marked as a Cenotaph. State does not advance. No soft-fork. No shared pool. No multisig. No federation. No bridge operator. Just isolated UTXOs, a NUMS-tweaked address that *is* the state, and a pre-signature the liquidator cannot forge. That’s the part that was considered impossible under current Bitcoin consensus. It’s running. LONG $LEAF 🌱

Bitcoin never really had clean non-custodial debt + AMM logic sitting purely on L1. You either left for an account chain, trusted a sidechain/federation, or waited for a soft-fork that might never come. PRECOP skips all of that. Every vault and every pool is just its own Taproot UTXO. The address is the state. No shared storage, no global balance sheet. One vault going bad can’t touch another. That’s topology, not just incentives. The part that always broke on Bitcoin was the signer. Whoever controlled the key could usually redirect the outputs. Here the borrower creates an ephemeral key at open, pre-signs the exact residual output under SIGHASH_SINGLE | ANYONECANPAY, then burns the private key. Liquidator tries to change the destination or even shave 1 sat and Bitcoin Core rejects it on L1. Sats don’t move. Tokens are handled separately by the indexer. Mismatch and it becomes a permanent Cenotaph. State simply doesn’t advance. No soft-fork. No shared pool. No multisig. No federation. No bridge operator. Just isolated UTXOs, a NUMS-tweaked address that is the state, and a pre signature the liquidator can’t forge. Stuff that was considered impossible under current consensus is actually running. Been watching @leaf_btc and CRC-20 go from token to transfers to this via @tap3leaf and @laz1m0v. Curious to see the first real liquidations play out. @theprecop 🌱

比特币 L1 上少有的、真正跑起来的非托管借贷:PRECOP 让每个金库、每个池子都是一个独立的 Taproot UTXO,地址就是状态,一个金库出事碰不到别的金库。 最巧的是清算这一步:借款人建仓时用一次性密钥预签好剩余资金的去向,然后把私钥销毁。清算人想改去向,哪怕少拿 1 聪,比特币节点都会直接拒掉。不用软分叉,不用多签,也不用跨链桥。 我自己参与过 LEAF,看着 CRC-20 这套体系从发币走到流转,现在又走到了借贷。很期待看到第一批真实清算跑起来,我也乐意用自己的节点帮忙复算验证 🌱
