I have both bitcoin & ether apart from hundred other coins; earning profit is different from technical merit. I spent a long time studying ethereum as a promise for something incredible but in the end I realized its just the power of blockchains & can be done using bitcoin too. What I do not like in ethereum is the nature of origin of ether which makes it just an IPO coin.

Unfortunately, I'm trying to obtain a small amount of ethereum currency to experiment with this..

And I just killed my thread doing 1M hashes a sec, because I found out that 6MHash/sec = 5 Eth/month on average.

I'll spend my time learning other things, mainly because this is inaccessible to me.

> SatoshiDice is a dapp that was built using bitcoin. But SatoshiDice was not trustless; it was only provably-fair. By sending your dice bet to satoshidice, you were trusting them to actually pay you if you won instead of just keeping your money (though you didn't have to trust that they were using a fair die). An on-chain dice contract is completely different, because there's no central operator that you have to tru…

You are right my example was wrong. Yet dapps can be done using bitcoin nevertheless.

Earlier quoted context omitted.

It was a pump'n'dump. Lots and lots of people on the Reddit bitcoin-related subs reported PM spam about Ethereum, for instance.

Pump and dump the way you phrased it, seems to auggest the entire thing is a pump and dump scheme. Either way, the price fluctuates woldly as people try to do this scheme, but the company raised $15m and appears to be actively developing the tech. So whether it works(it appears promising) or not, they seem to be svidly trying

I'm speaking specifically of the price rise then fall in the last couple of weeks.

The fundraiser, of course, was a pre-mined altcoin.

Yep ethereum has been out for what 6 months and look at all of development on top of it already. BTC has tons of VC money and I see nothing interesting beyond a few regulated exchanges. But oh ya we are all suppose to believe BTC can do all of this but apparently nobody really knows how. It's really just a bunch of people that think BTC is special because it was first, but it lost it's first mover advantage. https://…

Please give me an ethereum use case & I'll try to tell you how you can do it with bitcoin.

I have previously answered a few use cases here [https://news.ycombinator.com/item?id=10846788]

Is there a "Hello World" version of a DAC? What is the simplest contract I can make? And do I need a 3rd party oracle to confirm anything?

It would look something like:

contract Hello { string greeting; function setName(string name) { greeting="Hello "+name; } }

The solidity compiler will automatically produce a "getter" function to retrieve the greeting.

You can buy the Ether on an exchange.

Crypto has come a long way since Ethereum was first conceived and what was impossible only a few months ago is now 100% practical. Today there are A LOT of new techniques that allow us to largely implement decentralized autonomous applications on any blockchain (no matter how limited) - a fact I feel often gets missed out in all of the Ethereum hype. If you have a lot a techniques like zero-knowledge proofs, homomorp…

> Interestingly enough - there's even ways to make the answer to any computable problem the keys to unlock a Bitcoin payment

Sure, bitcoin script can in theory compute any computable problem (as can any turing machine). But it doesn't have native access to the data it needs, so pretty much any input you'd want to use needs to be put there by a trusted "oracle" (through a clever encoding into UTXO logic). For example, bitcoin script can't compare the amount of coins sent to two different bitcoin addresses, so you'd need to use oracles to do that [1]. In ethereum script it is trivial to do it on-chain (no oracles needed), since it was designed from the ground up for such use-cases (i.e. "smart contracts").

the bitshares, nxt, insert any blockchain project all say the same thing yet none of them comes even close to the amount of dev taking place on ethereum. hmm why is that....
