Re: [GNUnet-developers] blockchain vs gnunet, Integration of concepts?

[Bart Polot]

Worth keeping in mind: blockchain does not necessarily mean energy-intense, there are many blockchains that work based on history. They use proof-of-stake instead of proof-of-work. They are not without problems and there are a lot of proof-of-stake-SomehingElse to address those, but it is possible to make it work.

Hi!

First of all, I think having a blockchain in GNUnet is technically
possible. But the question is for what.  For a payment system, we're
working on GNU Taler (taler.net), which has a more strong ethical
foundation and should be less expensive to operate.  Blockchains also
generally worry me because of the inherent high demand for energy.

I do see some potential use for a blockchain in GNUnet to facilitate
computations or timestamping services a la Ethereum, but even there I'll
need some more convincing data before I believe it's viable (but
Ethereum is certainly a worthwhile experiment / research direction).
Still, for now, I plan to focus my efforts in other areas (GNS, ATS,
Conversation, PSYC, multicast, etc etc.).

If you want to see blockchain-based applications, I'd suggest you work
with the Ethereum folks for now, they seem to be the best team for that
today. And if those really take off, I'm sure we can find a way to
integrate Ethereum with GNUnet (AFAIK, some of their devs are already
thinking about that.)

Happy hacking!
