The future of digital currencies and the question of whether that future involves decentralized applications took centre stage at CoinSummit San Francisco on 25th March in a talk that included Ethereum's Vitalik Buterin; Mastercoin Foundation's David Johnston; and NXT's Brian Snyder.

The panel was moderated by Adam Levine of popular online podcast Let’s talk Bitcoin.

The purpose of distributed applications is to better economize digital resources.

The concept of bitcoin was the impetus for this, but Vitalik Buterin of Ethereum, David Johnson of Mastercoin and Brian Snyder of NXT believe that there are many use cases for cryptographic systems outside of just money systems, the use case that bitcoin has popularized.

Ethereum's Vitalik Buterin told the CoinSummit crowd that cloud storage is one example of decentralization disrupting software:

Such forward-thinking ideas were on full display in a talk that discussed how bitcoin could have ramifications beyond the world of finance, and how today's entrepreneurs are working toward this goal.

The panelists talked at great length about distributed uses beyond bitcoin, and how soon these ideas will come to life.

Mastercoin's David Johnston, whose organisation provides a protocol that uses bitcoin to enable embeddable records such as smart contracts, said:

The proof-of-stake cyrptocurrency NXT is focused on fraud prevention via the use of tokens, Brian Snyder told the audience. The idea is to build something distributed but also provable and secure.

"I've seen credit cards get hacked, I've seen IDs hacked," Snyder said.

Ethereum is building distributed autonomous corporations, or DACs, to offer more complex functions to enforce the advanced functions of money.

Said Buterin, the core developer of Ethereum:

He said that Ethereum is focused on building a more scalable bitcoin that can do much more than just spend.

Added Buterin: "I think the reason to do this independently [of bitcoin] is all about scalability."

The panelists agreed that Bitcoin's rising price and hashing power are major problems, ones that they say squeezs out the mainstream's interest in building out its infrastructure.

Said Buterin:

Alternatives such as NXT, Mastercoin and Ethereum are next-generation software concepts that can inject new ideas into the cryptocurrency community. Mining is important for today's cryptocurrencies, but new ways to offer incentives to the community are going to be important.

Said David Johnston:

The talk concluded with what David Johnston called 'Johnston's Law':
