This page exists so that the narrow claim made in the book can be checked rather than believed. It lists the public, on-chain artifacts left by the reference implementation, states plainly what they do and do not prove, and carries the running list of corrections to the text.
本页的存在,是为了让书中所作的那个有限的主张可以被查验,而非被轻信。它列出参考实现留在链上的公开痕迹,坦白说明这些痕迹能证明什么、不能证明什么,并持续登载对正文的勘误。
The implementation's settlement layer writes to Base Sepolia, a public Ethereum layer-2 test network. Records there are timestamped by consensus and cannot afterwards be altered or removed by anyone, the author included. Both artifacts below can be opened on any public block explorer.
该实现的清算层写入 Base Sepolia——一条公开的以太坊 Layer-2 测试网。其上的记录由共识加盖时间戳,此后任何人(包括作者本人)都无法更改或删除。下方各项均可在任意公开区块浏览器中打开。

A test network is a test network, and its history is not guaranteed to outlive a book. So the same proof hash was written a second time, to Base mainnet — the live chain, where records are not swept away — in a transaction that moves no money and does nothing except carry the hash into permanence.
测试网终究是测试网,其历史未必比一本书活得更久。因此,同一份证明哈希被第二次写入 Base 主网——那条真实运行、记录不会被清除的链——通过一笔不转移任何资金、除把哈希送入永久留存外别无他用的交易。

It is the plainest transaction that could be devised: zero value, sent from the address to itself, its whole purpose being the thirty-two bytes of calldata it carries. Those bytes are the same proof hash recorded in the settlement above. Read both and compare them. It cost a fraction of a cent, and it will outlast the test network, the prototype, and in all likelihood this book.
这是所能设计出的最朴素的一笔交易:零金额,由该地址发给自己,其全部用意就在于它携带的那 32 字节 calldata。这些字节,正是上面那笔清算里记录的同一份证明哈希。把两者读出来比对即可。它的成本不到一美分,却会比测试网、比原型、多半也比这本书活得更久。
That the machinery described in the book was built, deployed and run, and that it left a permanent, public, independently checkable trace of having done so. The record exists, and its timestamp is not mine to change.
它能证明:书中描述的机器确实被构建、部署并运行过,并且为此留下了一份永久、公开、可独立查验的痕迹。记录就在那里,而它的时间戳不由我更改。
The settlement transaction is the one worth reading closely. It carries two records in a single transaction: the movement of 25 test units from a payer's address to a different payee's address, and — inseparably, in the same transaction — the cryptographic hash of the settlement record, the proof layer the book calls L3.
那笔清算交易最值得细读。它在一笔交易中承载两条记录:25 个测试单位从付款方地址转入另一个收款方地址;以及——在同一笔交易中、不可分割地——该清算记录的密码学哈希,也就是书中称为 L3 的证明层。
What to look for on the explorer page在浏览器页面上看什么
from is a real payer address, not the zero address; to is a different address. A genuine two-party movement.0xb8e0deb771dedabfc2994988eac3eca930de2cd152b6878cf8e41f78fbed4705UBK-SETTLE-1784529632320.from 是真实的付款方地址,而非零地址;to 是另一个地址。一次真实的双方转移。0xb8e0deb771dedabfc2994988eac3eca930de2cd152b6878cf8e41f78fbed4705UBK-SETTLE-1784529632320。The distinction the book keeps bright throughout applies here too: mechanism demonstrated is not system delivered, and neither is institution built.
全书始终分明的那条界线在此同样适用:机制得到演示,不等于系统交付,更不等于机构建成。
Both contracts' source code has been published and verified on the explorer, so you can read what they actually do rather than take their behaviour on trust. The token is a standard ERC-20 built on OpenZeppelin libraries. The anchor is a single function of a few lines.
两个合约的源码都已发布并在浏览器上验证,因此你可以直接读它们究竟做了什么,而不必凭信任接受其行为。代币是基于 OpenZeppelin 库的标准 ERC-20。锚定合约不过是寥寥数行的单个函数。
Verified source已验证源码
Neither of those contracts is the kernel, and the kernel is not published. The book describes the architecture — the ideas and the reasoning — and withholds the implementation, which is protected as a trade secret. That boundary is deliberate and is stated in the book rather than concealed. An address, a hash and a transaction give nothing away: they carry no business logic, no data model, no code. The proof that it exists is public; the design stays private.
这两个合约都不是内核,而内核并未公开。本书描述的是架构——理念与推理——而保留了实现,后者作为商业秘密受到保护。这条界线是刻意为之,并在书中明言,而非隐瞒。一个地址、一份哈希、一笔交易,并不泄露任何东西:它们不含业务逻辑、不含数据模型、不含代码。它存在的证明是公开的;而设计,仍属私有。
Regulators, prospective partners and academic examiners can be given a closer look under appropriate confidentiality, on request.
监管机构、潜在合作方与学术评审者,可在适当的保密安排下、经请求获得更进一步的查看。
Every factual claim in the book was checked against a primary or reputable secondary source before publication, and a chapter-by-chapter audit record was kept. Errors that survived that process are mine, and they will be posted here as they are found, with the date and the correction.
书中每一处事实性陈述,均在出版前对照一手来源或可靠的二手来源核对过,并保留了逐章的审核记录。若仍有错误漏过这道流程,责任在我;它们一经发现即会连同日期与更正登载于此。
No corrections recorded to date. This note will be replaced by a dated list as entries arise.
迄今未记录任何更正。待有条目出现,本说明将被一份带日期的清单取代。
If you have found an error, please write with the page or chapter, the claim as printed, and the source you believe is correct. Corrections are welcome and will be credited unless you ask otherwise.
若你发现了错误,请来信注明页码或章节、书中印出的说法,以及你认为正确的来源。欢迎指正;除非你另有要求,更正将署名致谢。
Figures and regulatory positions in the book are given as they stood in 2026, and the text says when a number was true rather than pretending it is permanent. Where published sources disagreed, the book states the range, or uses the formulation that is true on every published basis, rather than selecting the most striking figure.
书中的数字与监管口径,均以其在 2026 年时的状态给出;正文会说明某个数字在何时为真,而非佯称它永久成立。当已发布的来源彼此不一致时,本书或给出区间,或采用在所有已发布口径下都成立的表述,而不去挑选最惹眼的那个数字。
