Jimmy Song on what EasyPaySy could do for Bitcoin

Speaking today at Advancing Bitcoin, in London, Bitcoin educator Jimmy Song devoted his talk to explaining what EasyPaySy means for Bitcoin.

In December, José Femenías Cañuelo released a whitepaper called “EasyPaySy,” which he sent on the Bitcoin mailing list. But beyond a highly technical article in Bitcoin Magazine, the idea saw little exposure. Luckily, Song was here to make it simple.

He started by pointing out the obvious. BitcoinBitcoin addresses are complicated strings of alphanumeric characters, which aren’t easy to use, he said, identifying a common problem with using Bitcoin. While this issue is commonly solved by using QR codes, they add a layer of complexity that could be avoided.

Jimmy Song: The making of a Bitcoin maximalist

Bitcoin entrepreneur and educator Jimmy Song is standing on an upturned beer barrel in Riga’s oldest cellar restaurant, surrounded by ravaged hunks of meat, dead birds and androgynous-looking serving staff dressed like characters in the Latvian version of Grimms’ Fairy Tales. An auction is in progress.  Bids rain down from Song’s fellow Bitcoin enthusiasts—including Francis Pouliot CEO of Canadian exchange Bull Bitcoin, and What Bitcoin Did podcast host Peter McCormack.

“There’s a new approach using locator IDs,” he said, adding, “Instead we could use the transaction location within the blockchain and that’s a lot easier.”

How would EasyPaySy work?

The rough idea is that the location of a Bitcoin transaction (unique to every transaction) is easier to use as a reference when pointing to an address.

“It comes down to block height and transaction number. Every block has a list of transactions. Just put wherever that transaction happens to be. That’s a lot easier to remember. That’s the basic idea,” he said.

With EasyPaySy, you would create IDs that refer to these addresses, based on their block height and transaction number. An example ID would look like this: “cerealriver.limit.”

If this seems familiar, the end experience for the user would look like the Ethereum Name Service, which uses easy-to-remember names instead of EthereumEthereum addresses. Similarly, Handshake wants to offer a service like this for Bitcoin and other cryptocurrencies.

But EasyPaySy is different. Unlike these services that connect human readable names to blockchain addresses, it would connect them to the location of the transaction instead.

The pros and cons of EasyPaySy

The result is greater privacy. It’s much harder to find a Bitcoin address when given the EasyPaySy ID, Song said.

Jimmy Song wants you to run Bitcoin on your phone, safely

Try downloading the entire Bitcoin blockchain onto your phone. It's a hefty chunk of data, some 200GB at last count. While some high-end smartphones might be able to cope with the load, it's way too big for most of us--and that's important, especially when it comes to making transactions on mobile. This is why we use wallets. These are apps that allow you to access great hulking blockchains without having to store all that data locally. The problem is, these wallets are often reliant upon third-...

There are a few catches, however. EasyPaySy transactions would be larger, taking up more space on the Bitcoin blockchain—where space is at a premium. It would be hard to make anonymous transactions using this method, Song claimed. And they would be incompatible with light clients—that let you run Bitcoin on smaller devices like phones.

The last issue is probably the most pressing for Song, who runs Neutrino—one of the most popular Bitcoin light clients. But he didn’t seem to mind.
