$500m for what I understand to be a crypto bank account?

"Board says we need to invest in crypto. This is crypto."

Are you implying that a company that processes hundreds of billions of dollars in transaction volume is thinking of acquiring this company for the hype alone?

Cool, never heard of it and visiting their website it is not exactly clear to me what their product is. I have never quite understood how companies just have a single landing page with no publically available product or service (as it seems) and still get bought for several hundred millions.

I've built a similar product for a well-known company in the space (and competitor to this company & Coinbase) and co-led the development of the crypto custody at Novi (Blockchain subsidary of Facebook). Happy to answer more questions though they do not provide much insight into their technology publicly.

Curv provides MPC-based crypto custody solution wi. I'll be over-simplifying but they allow private keys that protect large sums of cryptocurrencies to be split in encrypted portions called 'shares'. These shares are both created and used in a fully distributed manner (just like threshold signing / or 'multi-sig'). You generally define a threshold 'm' out of 'n' that's mathematically required to get a valid cryptographic signature.

An attacker would need to compromise a sufficient quorum of these keys simultaneously in order to sign blockchain transactions that would extract the funds somewhere else. As you can imagine, the complexity of such attack is highly correlated (and actually tends to grow exponentially due to several factors) to the quorum threshold 'm'.

Curv seems to allow financial institutions and all kind of institutional investors to create the shares, manage them and use them securely to sign transactions.

The argument they provide which makes little sense to me is that there is no 'private key'. They just seem to play with jargon as the shares are pretty much equivalent to individual keys in a multi-sig system, or at least hold the same power and have same results in compromise scenarios.

From the use cases you can tell they basically manage the risk of holding crypto for institutional clients while providing an easy to use interface, that's definitely worth a ton of money if done properly.

Is that a bad strategy? We've seen billion dollar IPOs on hype alone. In 2021, it might even be the winning strategy.

Disclaimer: I work for a competitor.

Multi-party computation (MPC) enables you to participate in public key cryptography with shares ("parts") of a private key divided between multiple participants from the get-go, i.e. without ever having the private key in memory at any point in time.

So for example, if you divide the shares between mobile devices and servers then all of them would need to communicate with one another to sign a message without any of them knowing the private key. There are variants (e.g. 2 out of N, etc.), but that's the gist of it.

Connecting it to cryptocurrency wallets, you can then use this scheme to create accounts where the control is shared between multiple devices and "mathematically" it doesn't matter then if one of the devices is compromised - it could never do anything on its own.

Remember that there are people behind these decisions and they are largely rational actors. Someone at PayPal is getting a big promotion and bonus from pushing this deal. If crypto goes nowhere and they shut down this project, then it can be rationalized as "getting in too early" or some other "unforeseen externality" that happened, totally out of their control. But the promotion and risk taking executive will have solidified his/her position with headcount and other markers of success.

There are always things we don't know going on behind the scenes for these types of moves.

Remember when Marissa Mayer was poached from Google to run Yahoo, and the first big move she made in a series of bungles included buying Tumblr for $1.1bn. Then she termination the option for employees to wfh. Then was later revealed that she had consecutive bad performance reviews at Google and was not going to get further promotions there before she jumped ship.

Edit: I'm just bringing up Marissa Mayer as an example and maybe misremembering the specifics since this was 8 years ago at this point. There are plenty of other examples of executives doing weird stuff that seem nonsensical from the outside. Jamie Dimond proclaiming bitcoin is a fraud while consecutively JPM buys a hefty investment in bitcoin. Or Bill Ackmann crying on CNBC while financially positioned for the exact opposite.

The difference between multi-sig and no private key is that the former is an implementation of the blockchain protocol (e.g. different in Stellar and Ethereum) while the latter is a generic algorithm/service. Different layer.

Heh, the $150 Trezor Model T supports the "m of n" key thing. Repackaging the tech and selling it to business is really not a bad startup idea.

> Happy to answer more questions...

Does these kind of solutions work for every cryptocurrencies? For example does is support Bitcoin? Or is this something that needs some kind of smart contract like those provided by Ethereum?

And another question: what about optionally fully anonymous transaction as in ZCash, does the scheme work to sign tx done using ZK proofs too? Or fully anonymous ones, like David Chaum's upcoming "xx coin"?

Multi-sig for retail is great, and I use it myself. But you're held to a completely different standard in term of security and compliance as a financial insitution. And this applies to: software, hardware, operations, ceremonies, business continuity (what if the business goes bankrupt, what if country 'xyz' gets nuked etc..).
