Speaking as an academic who studies distributed systems, my advise is to stay away from anything that relies on a public DHT to work correctly. They're vulnerable to node churn, Sybil attacks, and routing attacks. The last two are par

It's also a long, long, long way from becoming a currency with properties most people actually care about. Wild price fluctuations don't help it's cause, for example.

Disclaimer: I work for blockstack.org, a company trying to build out the decentralized Web. I mostly agree with this line of reasoning. Users don't care about decentralization, and for developers it's much easier and more lucrati

Routing attacks aren't specific to DHTs--they affect all kinds of structured overlay networks. If your routing layer allows anyone to route requests, then the attacker can insert its nodes into the routing layer (e.g. as a sybil) and

IPFS uses a DHT to look up and announce the availability of content. DHTs are notoriously vulnerable to routing attacks, whereby an attacker can insert nodes into the network and take control of individual hash buckets. This is achieved b

Nope. You have to re-announce them periodically (and this is ignoring all the routing attacks you can do on IPFS).

I don't think the distro maintainers had that much say, since the most popular Linux desktop software began to depend on it. It started with GNOME, and now KDE is on its way. This basically forces their hand--if they want to provide

Uselessd has been abandoned, as your link points out. The rationale [1] is, predictably, that "mangling systemd into something a bit saner turned out to be frustrating" and it was "a fool's errand" to have tried. [

It's probably because all the features they need are already met by existing tools. In that case, there's no need to write more code.

The fundamental problem seems to be that, when positioned against the same threat model as Bitcoin, all the PoW alternatives reduce to an obscured form of PoW. Put another way, a PoW alternative proposal must be designed such that partic

The problems with using DHTs for naming are: * Locality-unaware routing. Your lookups can bounce around the planet a few times before reaching the right key, leading to extremely high and extremely variable latency. This can be mitigated

Don't forget that like BitTorrent, IPFS uses a DHT to route requests. This makes it vulnerable to DHT routing attacks, where an attacker can Sybil the system and censor all of the routes to a block.

No. First, solutions to Byzantine agreement for known numbers of processes predate Bitcoin. Second, Nakamoto Consensus is not Byzantine agreement. Byzantine agreement forbids committed writes from being reverted, and each replica sees t

What was false and misleading? Didn't the DAO creators and enthusiasts insist up and down that the code is the irrefutable interpretation of the contract? Doesn't ethereum.org still state that smart contracts are "applica

I've always thought of Bitcoin as a rate-limiting token. The only thing it actually buys is space on its blockchain, which you bid on and pay for via transaction fees. In fact, this will probably be the dominant use-case in a few year

Sure, the EVM may be fine, but the biggest flaws lie in the design of Solidity. Solidity makes it very easy to introduce reentrancy bugs like the one that led the DAO to be exploited. As long as Solidity remains the de facto smart contr

You're right, IPFS does not try to address dynamic content. I don't speak for the authors, but I think their opinion is that doing so is out of scope. I think they expect the application to represent each piece of mutable conten

I don't think IPFS is trying to replace HTTP; it's trying to replace URLs. IPFS's goal is to offer universal content-centric resource location as an alternative to the Web's host-centric resource location. This is a ni
