Why do you say it's an attempt to make Bitcoin more efficient? It's essentially exactly the code base of Bitcoin core with some very minor changes including a block size commitment in the future. Seems pretty clear that it is about control of that code base, and not really the technical underpinnings which are almost identical.

I think the issue is that people have a vision of what Bitcoin is, that doesn't align with the reality of a proof-of-work system with a computation bound hash. The block size is basically orthogonal to the proof-of-work, and the proof-of-work is distributed in the sense that anyone can do it. There is nothing stopping any entity from doing the proof-of-work if they have the resources and capabilities. So this idea that there will be one company that is the only one doing Bitcoin doesn't really make sense if it's cost competitive for other companies to be involved, regardless of the computation or bandwidth requirements.

End users can still validate transactions via SPV, which is completely valid and provable without storing the entire block chain. Consensus relay nodes can do the same thing, although they will start dropping off the network when the bandwidth costs become prohibitive. So in a small block system we have an extremely limited amount of space for transactions, which means the cost will eventually be excessively high and result in settlement between big players. That's the choke point that allows for KYC and AML. You can submit a transaction to the network, but you can't afford to because there isn't enough bandwidth to service your request so you are forced into regulated channels, onto exchanges, or through third party choke points that can be audited. To a certain extent this is already happening.

People who want small blocks for Bitcoin really need to be thinking about using an Alt coin, it was never in the plans to have an extremely low bandwidth pipe to keep things decentralized when the proof-of-work is by default a centralizing force.
The code on the endusers machine needs the API key to function, since there is no server on the publishers side involved, right? So you have to give the API key to them in some way, if directly embedded in the code or not.

It’s only the binary logs that need to be base 12. This is the approximations inherent in the 12-step-per-octave equal-tempered Western music scale. Memorizing just two facts gets you a long way:

3 ~ 2^(19/12) -> lg 3 ~ 1;7 or to be more precise 1;703

5 ~ 2^(7/3) = 2^(28/12) -> lg 5 ~ 2;4 or to be more precise 2;3a4

This makes 2^0;7 just about exactly a “perfect fifth” 3/2 (off by about .1%), and 2^0;4 almost a “major third” 5/4 (off by .8%).

If you step up a scale by 2^(1/12) or in log scale 0;1 increments, you can find close fractional approximations to most of the steps. Then I happen to also know that 0;06 is ~lg 35/34, but that one obviously isn’t nearly as important or easy to work with.

It's not lucrative enough. The product is worth far more than the measly bounty. Sure, claim that 15 dollars in bitcoin, and never receive another pre-release copy again, or... strip it and continue business as usual.

This model really only works when most encoders are not aware the tag is there at all, and don't strip it.

Alternatively (as some other comments suggested) Custos buries additional tags without revealing them, in which case they act just like all sorts of other watermarking companies doing the same thing (not terribly effectively).

Python is an excellent glue language. It's surprising to me how difficult or non-intuitive it is to be able to interact with long running processes... especially with this nice new asyncio.

I know it's not as simple as it sounds (or people wouldn't still be using Tcl based Expect scripts eveywhere)... but it's still some complexity that could be hidden away in a library somewhere.

>I wish we had a faster way to test out more competing theories and models.

Luckily, the state of actual cognitive science and neuroscience is fairly far ahead of, "Gosh there's all these things and we just don't know." Unfortunately, MIT-style cogsci hasn't generated New Jerseyan fast-though-wrong algorithms for Silicon Valley to hype up, so the popular press keeps spreading the myth of our total ignorance.

Besides which, we do know what's missing from deep learning: the ability to express anything other than a trivial Euclidean-space topological structure. We know that real data is sampled from a world subject to cause-and-effect, and that any manifold describing the data should carry the causal structure in its own topology.

The issue is that both groups derive from a single block chain at some point, so everyone who held BTC before that split can spend them on both forks, whereas those who receive them or mine them after the split only hold the currency on one fork.

Additionally, if the split of hash power is highly asymmetric, then the difficulty of the majority fork will become much higher than that of the minority fork, over time. This opens the minority fork up to 51% attacks. Say the split is 90/10, then just 15% of the miners from the majority could team up and switch back to the minority fork to wreak havoc.

> Completely illogical...

Agreed.

Your argument is logical but vacuous[1]. Mine is logical, and what's more, proceeds from assumptions that aren't oblivious to empirical observation.

> You claiming a system which strictly enforces property rights always leads to a system which disregards property rights is absurd.

My claim is that political power is dynamically allocated, not statically allocated. In free markets, money buys power. Power is then abused to rig the rules of the game.

So even if you start in an ideal free market state, you'll quickly converge to cronyism. in this sense, opposition to "crony-capitalism" and advocacy for "free market capitalism" is an inconsistent position. Again, not as a matter of your definitions and logical derivations. But as a matter of observed reality!!! If you definitions and derivations contradict reality, the problem is not with reality but with your model of reality.

> Are you arguing that in order to keep people from wielding governmental power against others, we need to strengthen government? Really?

No. Where do you find me advocating for "strengthen[ing] government" in this thread? In fact, I think my critique of the World Bank is most commonly read as a critique of how strong (certain) governments have become. But actually I don't have any strong ideological advocacy, and even the World Bank/IMF have benefits and drawbacks that aren't so easy to categorically praise or condemn in broad strokes (see: various other threads).

I'm not the one claiming a theory of utopia. I'm just pointing out the absurdity of make such a claim by carving out increasingly arbitrary and anti-empirical definitional distinctions.

> What you're arguing is...

What I'm arguing is that definitions and logical derivations exist in service to describing reality. You have these two things -- reality and the tools we use to model reality -- the wrong way around.

Again, stop arguing about definitions and logical derivations stemming from those definitions. Answer the claim that free markets beget cronyism as a matter of empirically observable fact. Anything else is vacuous.

Hi HN!

In my work as a PHP developer I sometimes get frustrated when I or a teammate gets the "release version" wrong of a library that we use, and a backwards incompatible change gets released under a "minor" or "patch" version bump. This usually causes breaks for the unlucky person who updates the dependencies when, if everybody stuck to true semantic versioning, everything should work exactly as it did before.

I'm working on this proof of concept to help; it analyses proposed changes in a GitHub pull request and gives a breakdown of the types of changes (backward incompatible or no, etc). Based on this it recommends what the next release of the project should be.

At the moment it only works for opensource PHP projects, I invite you to give it a spin on an opensource project you may be working on. Feedback would be hugely appreciated.

Many thanks!
If we only wanted to track the current unspent outputs we're sitting at 54M which interestingly has been holding relatively constant since June. Where as the total number of transactions (size of blockchain in general) is at 240M and is strictly monotonically increasing.

See UTXO here: https://blockchain.info/charts/utxo-count

See total TX here: https://blockchain.info/charts/n-transactions-total

Every block for the near future will include one new UTXO, but it can increase, decrease or keep the total number of UTXO the same.

> End users can still validate transactions via SPV, which is completely valid and provable without storing the entire block chain

fraud proofs don't work because if you want to prevent someone from creating a fraud proof, you never send them the data that would be necessary to prove a fraud ("the block is too big! nobody (but some list of companies) have the bandwidth to support the enormous bitcoin network!"). SPV users don't require (nor check) the block data-- exactly the kind of scenario where you need in place so as to hide fraudulent double spends or other rule violations.

> the proof-of-work is by default a centralizing force

sounds like a good argument for regular pow change hard-forks. also to be watchful for economies of scale-- but economies of scale can hide pretty well i think, even after significant capital accumulation, it's an interesting problem.

The ledger of every transaction has only ever been a means to an end, that end being a cryptocurrency... and it's still necessary in Lightning Network as a way to resolve fraud and as a monetary backing, it's just not used in every single transaction.

In practice, a ledger of every transaction that is copied to the hard drives of a sufficient amount of bitcoin users is a terrible idea. It doesn't scale, at all. We need better solutions. Lightning Network is one that's potentially viable in the short term - and we're seeing more people play with radically different cryptocurrency designs (e.g. Iota) in the long term.

"This means their expected return is lower, not higher, they aren't getting a larger percentage of found blocks, and those blocks occur farther apart."

The blocks would happen farther apart, but it would also mean that the remaining miners would have much higher change of actually finding a block, since there would be less competition. Also as there would be the same amount of transactions and less blocks, the blocks would have more collected transaction fees -> bigger reward. Also probably people/exchanges would increase the fees since competition would be bigger to get the transaction to a block.

Also, it would make sense for exchanges etc to buy some mining power. That would make blocks appear faster, and also they would get the mining reweards, so it might be net positive. Or just simply bribe some miners to mine the valid chain. Very easy way to do that would be just to increase the transaction fees that they put to transactions.

>"it is amazingly hard work to churn out quality content throughout the year."

One of the best examples I've seen of this was David Gardener's Rule Breaker portfolio in the 90s. He publicly wrote up analysis after analysis on technologies and companies, along with the occasional announcement he was buying or selling a stock. There were a few whiffs, but he got AOL in '94, Amazon in '97, and Amgen, eBay and Starbucks in '98. He was highly visible, forward predicting and right in a way that was quantifiable. I'm not a fan of the direction his business (fool.com) has gone in the past 10 years, but throughout the first dotcom boom, he made some great contrarian picks despite extreme push-back, particularly for Amazon.

The same can be said, on the whole, of the predictions of Ray Kurzweil. Even though he wasn't talking about individual companies, there were specific predictions and timelines that could be compared to predictions of his peer and what actually happened (e.g. a chess AI beating the top human player, the mapping of the human genome by 2000, etc) http://bigthink.com/endless-innovation/why-ray-kurzweils-pre...
Came to the comments to say exactly the same thing. "Content is king" really refers to the service becoming invisible enough to let the users get what they want out of it.

As product owners/creators, we can easily obsess about our platform and loose sight of the needs of the users we set out to serve, then scratch our heads when users jump ships to a crappier service (in our biased judgement) which happens to have more content.
