Programmable Money and value capture

Money serves three purpose – unit of accounting, a medium of exchange, and a store of value. Cryptocurrencies have been compared to Programmable Money. Anything programmable requires an experimentation platform for iterations and improvement. Bitcoin seems to have won the “store of value” battle. Ethereum has the developer mindshare and is the preferred experimentation platform. Multiple cryptocurrencies are still fighting the battle to be the medium of exchange.

The amusing part is that every cryptocurrency startup envies Ethereum’s developer ecosystem and is trying to attract developers. But there isn’t any real value capture being the experimentation platform. A successful product has a high chance of leaving Ethereum and migrating users to its chain. The real battle, I believe, remains in becoming the medium of exchange, being the programmable Visa & Mastercard equivalent.

The “key” problem in cryptocurrency

All cryptocurrencies are eventually tied to a “private” key. You lose this key, and the funds are gone, forever. Millions worth of bitcoins have disappeared from the circulation due to lost keys. You can memorize the key by mapping it into passphrase consisting of memorizable words but if you forget that, like many others, the coins are unrecoverable. An alternative is to trust a centralized service like Coinbase, but then all the benefits of investing in a decentralized currency are gone. Lastly, one can use a hardware wallet, but again, if you lose the wallet, the key is lost. If you keep the key on your device, then a malware might target and try to steal it someday. Thus, even if you are bullish on cryptocurrencies, there are no good decentralized ways of holding a significant chunk of your net worth in cryptocurrencies.

The problems are compounded further by the fact that to a great extent, the key access is all or none. If you lose your key, you lose all the funds. If I got hold of your key, I could transfer 100 % of your funds, irrevocably. Compare this to your ATM debit card, if I get hold of it, along with your pin, there is only so much damage I can do before the ATM limit hits. Further, your credit card used on a malicious website can hit you with a limited amount of fraud before the fraud warnings block the card to prevent further loss of funds.

An ideal approach, hopefully, will consist of decentralized smart contracts comprised of multiple keys tied to the same passphrase with a different set of transfer limits. So that, if one forgets one word in the passphrase and cannot access 100% of the funds now but can access at most 1% funds every day and slowly drain out their account to a newer account. Some of these unlocking codes will be held at different places, some centralized services for custody and ease of use; some kept on the personal device for ease of use where even if they get stolen the damage is contained. A further addition could be a beneficiary account where the funds would be transferred to in case the account lays dormant for a certain period.
