It would be great to have a decentralized relay network! Right now this is a centralized bandaid solution, which is unfortunately necessary because of many well-known vulnerabilities of Bitcoin's p2p layer. E.g. - Tampering with the De

Well, that has never been the case. The algorithm of the network is defined by the most widely used implementations, which so far has continued to be Bitcoin Core. Bitcoin Core is maintained by a group of humans, who use some form of decisi

Yes! See suggestion #2 in the article. The block-chain is a great tool for decision making, since it makes it possible to get a transparent, permanent, public log of all the comments and opinions that go into the decision. So far, in-blockc

I wrote a paper called "Authenticated Data Structures, Generically" [1] that's closely related to this. It shows how to automatically make a "merkleized" version of any (pure functional) data structure. The original

"Full node" has a specific meaning in Bitcoin. It's a node that validates the entire blockchain and all incoming transactions, and relays transactions to peers. This is different than a "light" node or just a wallet

My opinion is the Ripple consensus algorithm doesn't yet meet the security claims its stated to in their whitepaper. There's an ongoing discussion here: https://forum.ripple.com/viewtopic.php?f=2&t=7801#p56432

We designed Permacoin with the goal of being rigorously secure. Our design addressed a bunch of problems that aren't (yet) addressed by filecoin. - Erasure coding (over the whole dataset) guarantees that you can't just drop some o

Yes, it's absolutely essential that a switch to a nonoutsourceable puzzle also comes along with a variance reduction mechanism. I have no clear winning solution for this part, but I've got a few ideas and have discussed them with

The basic idea for a delegation-breaking puzzle is outlined here: https://bitcointalk.org/index.php?topic=309073.0 The intuition (which is described in the original article, by the way) is that in this puzzle, whoever actua

The non-outsourceable puzzle discourages hosted mining as well as pools (though if users are trusting, then hosted mining might persist anyway). The non-outsourceable puzzle would have to be adopted at the same time as another change, which

I'm not an expert on StorJ, but I'm the Permacoin author. As far as I can tell, Permacoin is a possible candidate for the "proof of resource" puzzle that StorJ opaquely says they'll need (though they don't prov

Technical differences aside, proofofexistence.com predates the Cornell team's blogpost by a couple of months.[2] I am not surprised that the Cornell team did not cite the bitcointalk forum post (given the recent frenzy of their Selfish

BrowserID is a great long-term design for an identity system (much better than OpenID or WebID) and it already has a great UI. Use this right now on your fancy new webapp rather than asking your users to create a new account and password.
