2020年12月2日，Keep Network 市场和业务战略负责人 Carolyn Reckhow 在中国加密货币社群梭哈阁（ALL IN HOUSE）开展了一次 AMA 活动，主题是《让 BTC 以最安全的方式进入 DeFi》(tBTC, the Safe Way To Use Bitcoin in DeFi)，主持人为梭哈阁社区负责人 Andy，以下为 KeepDAO 对本次活动的内容整理：
Andy：首先欢迎tBTC项目的市场与策略负责人Carolyn Reckhow来到梭哈阁，能先简单自我介绍一下吗？
First of all, welcome the Carolyn Reckhow of the tBTC project to our ALLIN House. Can you introduce yourself first?
Carolyn Reckhow：谢谢梭哈阁的邀请！我叫Carolyn Reckhow，我在加密领域工作了五年多。我是ConsenSys最初的几个成员之一，负责领导运营工作，然后在Casa的Jameson Lopp工作。在ConsenSys和Casa的时候，使我能够在较为早期便接触到了比特币及以太坊。两年前，我加入了Thesis风险投资机构，负责业务战略，并在推动Keep和tBTC项目方面发挥了重要作用。
Andy：
So what prompted you to build the project?
很丰富的经验，特别是对于区块链行业来说。那么是什么促成了您建设这个项目呢？
Carolyn Reckhow：
Thesis is the leading crypto venture builder. In our portfolio, we have a number of exciting projects, including Fold, the Bitcoin credit card partnered with Visa, Keep, and tBTC. I’m going to focus for this session on Keep and tBTC, but encourage you to check out Fold, as well.
We built the Keep network technology out of the belief that dApps would need to use private data on a public blockchain. A great use case for the Keep network is DeFi and tBTC, a decentralized Bitcoin peg on Ethereum, which the Keep team and other contributors proceeded to build.
Thesis是领先的加密货币风险投资建设者。在我们的投资组合中，我们有许多令人兴奋的项目，包括Fold，与Visa，Keep和tBTC合作的比特币信用卡。我将在本次会议上重点介绍Keep和tBTC，但也推荐大家去了解一下Fold。
我们建立了Keep网络的初衷是：Dapps需要在公共区块链上使用私有数据。 Keep网络的一个很好的切入点是DeFi和tBTC，这是Keep团队和其他贡献者着手建立一个可以在以太坊上使用比特币的应用。
Andy：
Can you introduce tBTC? What is its vision and what problems is it trying to solve?
嗯，是这样，现在这个阶段 DeFi 对于区块链行业来说是一个很重要的应用方向。你能介绍下 tBTC 吗？它的愿景是什么，并试图解决什么问题？
Carolyn Reckhow：
The problem we saw that led to our building tBTC is that Bitcoin is still the largest market cap in crypto, but that BTC holders are increasingly looking to participate in DeFi and other earning opportunities on the Ethereum blockchain. However, they had no way to do so that was safe and consistent with Bitcoin values such as being decentralized and permissionless.
我们之所以建设tBTC是因为现在比特币仍然是加密货币中市值最大的项目，BTC持有者越来越多地希望参与DeFi和以太坊上的其他赚钱机会。但是，他们没有办法做到这一点，特别是无法安全的，使用去中心化方式和通过公链的方式与比特币价值保持一致。
That’s why tBTC is the only decentralized, permissionless bridge between Bitcoin and Ethereum. The Keep technology enables the keys to Bitcoin in the system to be stored safely and in a decentralized fashion, rather than in a wallet the team has access to. The team should never have the keys. The way it works is that anyone can go to tbtc.network, mint TBTC tokens for BTC, use the TBTC in DeFi or elsewhere on Ethereum, and then convert TBTC back to BTC any time. No intermediary needs to sign off.
这就是为什么tBTC是比特币和以太坊之间唯一的去中心化，无许可的桥梁。 Keep技术使系统中比特币的密钥能够以安全，去中心化地方式存储，而不是在团队可以访问的钱包中。团队永远不要拥有密钥。它的工作方式是，任何人都可以访问tbtc.network，为BTC创建TBTC令牌，在DeFi或以太坊上的其他的地方使用TBTC，然后随时将TBTC转换回BTC。无需中介机构即可退出。
Andy：
How does tBTC work and how does it achieve the value binding of Bitcoin?
那么，tBTC是如何运行的，它怎样实现的与比特币的价值绑定？
Carolyn Reckhow：
tBTC is a 1:1 supply peg, one TBTC = BTC and you can always redeem TBTC for BTC.
When a user wants to mint TBTC, they come to the dApp at tbtc.network and complete 3 simple steps:
Request a deposit
Send BTC & wait for BTC confirmations
Prove BTC deposit (with an SPV proof) & mint tBTC
When you request a deposit, behind the scenes a new 3 out of 3 signing group of Keep stakers (bonded 150% in ETH) is randomly selected using Keep’s random beacon. The signing group generates a PKH hash (a Bitcoin address) and after the depositor sends BTC SPV proof after 6 Bitcoin block confirmations, the system lets the depositor mint TBTC.
tBTC是1：1的对应，一个TBTC = BTC，您随时可以将TBTC兑换为BTC。
当用户想要铸造TBTC时，他们通过tbtc.network来到dApp并完成3个简单步骤：
1.要求存款
2.发送BTC并等待BTC确认
3.证明BTC存款（带有SPV证明）和铸造tBTC
当您要求存入资金时，会在后台使用Keep的随机信标随机选择一个新的3 out of 3的Keep Keepers签名组（以绑定价值150％的ETH）。签名组生成PKH哈希值（一个比特币地址），并且在6个比特币块确认后，存款人发送了BTC SPV证明后，系统允许存款人铸造TBTC。
The way to bring Bitcoin into DeFi is by preserving the original values of Bitcoin. Ultimately the winner will be the one that can appeal to Bitcoiners. tBTC is permissionless and decentralized – no intermediaries need to sign off. If that isn’t in line with Bitcoin values, I don’t know what is.
将比特币引入DeFi的方法是保留比特币的原始值。最终，赢家将是可以吸引比特币持有者的人。 tBTC是无许可且去中心化的-无需中介机构即可退出。如果这还与比特币的价值不符，那我不知道这是什么了。
Andy：
Compared with other BTC projects in Ethereum, what are the advantages of tBTC?
在你看来，相比其他BTC在Ethereum项目，tBTC有什么优势？
Carolyn Reckhow：
Compared to other tokenized BTC projects, tBTC is more decentralized and censorship resistant, we use proven crypto (Binance uses ECDSAs), and are open sourced and 3x audited.
与其他令牌化BTC项目相比，tBTC更加去中心化和不受审查，我们使用经过验证的加密货币（Binance使用ECDSA），并且经过开源和3重审计。
We see one of the biggest catalysts for DeFi growth, to really get to the next level as a stepwise change, is to get Bitcoin liquidity safely into the ecosystem for Ethereum DeFi and also other L1’s DeFi ecosystems that are starting off. We think in order to do this a project needs to be trusted by the Bitcoin community and in line with the Bitcoin community’s values of decentralization, it needs to be open-source, audited, and insured, and it needs to be thoughtful and responsible in terms of its growth. That project we believe is tBTC, and Keep – the KEEP token is used to keep the tBTC network decentralized – and we’re excited to provide that bridge.
我们看到DeFi增长的最大催化剂之一，是逐步改变，真正达到一个新的水平，就是将比特币的流动性安全地进入以太坊DeFi和其他L1的DeFi生态系统的生态系统。我们认为，要做到这一点，一个项目需要得到比特币社区的信任，并符合比特币社区分散化的价值观，它必须是开源的，经过审计的和有保险的，并且需要在考虑周到和负责任的情况下进行。就其增长而言。我们认为该项目是tBTC，而Keep-KEEP令牌用于保持tBTC网络的去中心化-我们很高兴提供提供这样一个桥梁。
Andy：
Will future projects involve cross-chain technology so that BTC assets can be converted on more public chains?
未来项目是否还会涉及到跨链技术，使BTC资产可以在更多的公链转换？
Carolyn Reckhow：
Yes! Our goal is to provide Bitcoin holders with the most in-demand options for earning on other chains. We started with Ethereum, and that is live today. Next we are building a cross-chain between BTC and the Celo platform. More are coming, and we will announce them early next year. L1 blockchain platforms are consistently selecting tBTC as the bridge of choice for its high standards of security and safety, and of course, that it is the only decentralized option.
是的，我们的目标是为比特币持有人提供在其他公链上赚钱的机会。我们从以太坊开始，这是我们正在做的。接下来，我们将在BTC和Celo平台之间建立一个跨链。将会有更多的东西出现，我们将在明年年初宣布它们。 L1区块链平台始终选择tBTC作为其高标准的安全性选择桥梁，当然，这是唯一的去中心化选择。
Andy：
How safe is the project and has it been audited?
项目的安全性如何，是否经过了审计？
Carolyn Reckhow：
Yes! tBTC has been audited.
Any security expert should doubt any claim that a project is 100% safe. What I can guarantee is that we have adhered to the highest standards of security best practices, and that we have an incredibly strong and security focused engineering team. tBTC has actually been triple audited, by ConsenSys, Trail of Bits, and a Bitcoin-specific audit. Its funds also have protection from Nexus Mutual. Last, the tBTC project has always been completely open-source, which means the community doesn’t have to take anyone’s word in terms of safety – they can look at the entire project themselves and make their own decision.
任何安全专家都应对任何声称项目100％安全的主张表示怀疑。我可以保证的是，我们遵守最高标准的安全最佳实践，并且我们拥有一支非常强大且以安全为中心的工程团队。 tBTC实际上已经由ConsenSys，Trail of Bits和特定于比特币的审核进行了三重审核。其基金也受到Nexus Mutual的保护。最后，tBTC项目一直都是完全开源的，这意味着社区不必在安全性方面信服任何人，他们可以自己查看整个项目并做出自己的决定。
Andy：
It seems that tbtc has made very careful planning in terms of project security.
看来在项目安全方面tbtc已经做了十分周密的规划。
Carolyn Reckhow：
The KEEP token powers tBTC minting and redemption. KEEP is a work token that enables the Keep network to preserve tBTC being decentralized and permissionless. The more usage there is of tBTC, the more usage there is of the Keep network, which requires the KEEP token.
KEEP令牌为tBTC铸造和兑换提供动力。 KEEP是一种工作令牌，可让Keep网络保留去中心化且无许可的tBTC。 tBTC的使用量越多，需要KEEP令牌的Keep网络的使用量就越多。
Andy：
tBTC has recently landed on Kraken. This is good news. Will there be similar plans in the future?
tBTC近期登陆了Kraken，这算是不小的利好消息了，未来还会有类似的计划吗？
Carolyn Reckhow：
Yes, we’re on multiple DEXs like Uniswap, and are in the due diligence process with other major global exchanges. We’re also on Curve and other DeFI protocols, and have plans to be integrated into platforms like MakerDAO’s MCD, Aave, and Compound.
是的，我们使用Uniswap等多个DEX，并且正在与其他主要的全球交易所进行尽职调查。我们也在使用Curve和其他DeFI协议，并计划将其集成到MakerDAO的MCD，Aave和Compound等平台中。
Andy：
The formal Q&A session is over. Thank you Carolyn for your answer. Then we will start the free Q&A session. We have three opportunities. Anyone who is interested in Keep can raise their hands and ask questions.
嗯嗯，看来项目团队对未来的安排已经有了十分清晰的规划。
正式问答环节结束了，感谢Carolyn的回答，接下来我们开始自由问答环节，我们有三次机会，大家对Keep感兴趣的可以随意举手提问。
Community Q&A ：
Q1：
Apart from DEX, will tBTC be listed on more centralized exchanges in the future?
TBTC和KEEP哪个成长速度最快？
Carolyn Reckhow：
Compared to other tokenized BTC on Ethereum projects like Ren, we have completely open sourced our client and the audits the project has had. We are also comparitively more decentralized than a project like Ren, which currently uses a multisig to hold BTC that can be controlled by the team. We also use proven cryptography (ECDSAs, which are used by Binance and others) rather than buildling our own new types of cryptography like Ren does.
To the exchange question — yes, we are in the due diligence process for at least 5 other major exchanges, both western and Asian centralized exchanges. We expect more listings soon.
与Ren等以太坊项目上的其他代币化BTC相比，我们已经完全开源了我们的项目并通过了审核。相比之下，与Ren这样的项目相比，我们的权力更加分散，该项目目前使用multisig持有可由团队控制的BTC。我们还使用成熟的加密技术（Binance和其他公司使用的ECDSA），而不是像Ren那样构建自己的新型加密技术。
对于交易所的问题-是的，我们正在对至少5个其他主要交易所（包括西方和亚洲集中交易所）进行尽职调查。我们希望很快会有更多的信息！
Q2：
What projects currently support tBTC for liquidity mining?
目前有哪些项目支持 tBTC 的流动性挖矿？
Right now the best opportunity for tBTC liquidity mining is on Curve.Fi, we have pools that are supported both by Cure and Keep for liquidity rewards. There are also some places to liqudiity mine on Sushi and Harvest I believe. But stay tuned for more information on liquidity mining! We will be adding new projects every few weeks and announcing them accros all our channels.
现在，tBTC流动性挖矿的最佳机会是在Curve.Fi上，我们拥有由Cure和Keep支持的矿池以获取流动性奖励。我相信，在寿司和Harvest也有一些地方可以挖矿。但是，请继续关注有关流动性挖矿的更多信息！我们将每隔几周添加一次新项目，并在我们所有的频道中进行公告。
