This exploit exists for all Ethereum-based blockchains coded in golang. Specifically, it most easily targets chains with overall low network hashing rates of 100GH/s or less. Krypton, Shift, Soil, and Expanse are all vulnerable. It might even be possible, by a large mining farm such as the one owned by Chandler Guo, to attack Ethereum Classic in this manner.

50 billion things connected to the Internet by 2020, they will need to communicate and store data somewhere. Cloud.
performant hashing systems
two crucial areas:
the smart contracts that run on consortia blockchains
the edges of blockchains where third-party data is given entrance
the back-end infrastructure for blockchains = cloud = amazon, msft, ibm, goog

It is how every company/government would react once they feel threatened. That is why I created a thread called "Decentralization is a dream" were I said that maybe cryptocurrencies does not need better adoption. It could kill them.

good caller. let us watch and see.
i can agree with most too.
but not all of them. some of them NOT at all.
but smart enough worth noting the OP see if he sticks with it.

Altcoins potential in a year from now (List) (25/08/2016) VultureFund https://bitcointalksearch.org/topic/altcoins-potential-in-a-year-from-now-list-25082016-1596714
this vulturefund should post some reasons to this list, i can agree with most of it but there are some options that doesnt make sense.... doge coin(x4??)? litecoin?
luna tickles cycle
i have not been hearing much about dogecoin all these days,it seems to me that it popularity is gradually going down,am i right ?
Doge can't die as long as Litecoin Lives (Merge Mining) , and LTC will be getting stronger over the next few months after the coinbase deal.
Their community normally holds around 40 sats, they only need it to be worth 1 sat to keep it alive.
So no they are not dying, and with the micropayments angle may be a stronger coin in the coming years.

some of the smartest lines of advice i've seen on crypto coin trading
a good start is : www.theforexguy.com
the strategies are the same as forex, and forex have way more material to study.
and dont ask for tips, you will need to learn... people here will say BS all the time so i wouldnt trust in tips if i were you.

Charlie Lee: Nuclear option of forking the codebase should only be used as a last resort. It's dangerous & irresponsible. (twitter.com)

By forking the codebase, I meant a contentious hardfork of the consensus protocol, the users, and the miners. (Not enough characters in a Twitter message!)
Some people have mentioned that it's ironic for me to say this because I forked Bitcoin to create Litecoin. That fork is drastically different than what BitcoinXT is doing. Litecoin uses a different proof of work, so that it's not competing with Bitcoin for miners. And by creating a new genesis block, it did not fork Bitcoin's userbase. Users and miners can choose to (or not) support Litecoin and it would have no effect on Bitcoin whatsoever.
People have also said that forking the code is just a push of a button and that people do it all the time with open-source software projects. So forking should be encouraged instead of discouraged. I agree with this, but Bitcoin is different in that there is one thing that you need to be careful with. And that is the consensus protocol. Bitcoin only works if everyone (well, the vast majority of the people) are on the same protocol. Any small change to the protocol will leave users on a different fork and not able to reach consensus with the rest of the network. And that's fine in most cases. Users/miners, finding that they are left behind (shorter chain length), can quickly fix their code to be back in consensus.
The reason why BitcoinXT is dangerous and irresponsible is because it could potentially destroy Bitcoin and split the userbase into 2 separate Bitcoin networks. There are very good reasons why most of the core developers and Bitcoin experts are super cautious with increasing the block size too quickly. But these reasons are hard to explain to regular users of Bitcoin. Yet, it is quite easy for Mike & Gavin to convince people that supporting BitcoinXT means supporting block size increase, which makes Bitcoin scale for worldwide use, and it's what Satoshi intended. BitcoinXT is set to trigger with 75% miner support. This means it can trigger with only 50% miner support + a lucky streak. Or if there are malicious people running NoXT, they can cause the trigger to go off without majority support. When that happens, there's no guarantee that the losing side will all switch to running BitcoinXT. Now you've got a split user base and miner base. Some wallets will support BTC, some will support BTCXT, and some may support both. Same for exchanges and payment processors. It's going to be total chaos. Miners will switch back and forth between mining BTC and BTCXT. Users will send transactions on one network and not know why the recipient didn't get it. The price for both coins will tank. If you thought Litecoin and altcoins dilute the value of Bitcoin, wait til you see what BTCXT does to the price! Actually, the market is already giving us a hint as to why BitcoinXT is such a bad idea.
A more responsible option would have been to set the trigger threshold at a real super majority of 90% miner vote. If it was set at 90%, the chance of a bad fork would be far less likely. But Mike & Gavin knows that there's no way they can get 90% support, so they would rather risk hurting Bitcoin in order to get their way. Mike has even mention using checkpoints to force the issue if XT doesn't get the hashrate majority (https://bitcointalksearch.org/topic/hearns-worst-case-scenario-checkpoints-in-xt-to-ignore-the-longest-chain-1089283). That is scary.
There's a better option. Really try to reach consensus. Unlike what you have been told, the devs actually support increasing the block size. They just couldn't come to a consensus on how much and when. And we still have plenty of time to get to a consensus. Next month, most of the devs and bitcoin experts are gathering in Montreal to discuss this topic to get everyone on the same page. Check out https://scalingbitcoin.org/montreal2015/

Bitcoin is open source and is still so young that no position, no matter how well entrenched it may be perceived, is unassailable.
We identified three types of tokens:
Debt Tokens
Equity Tokens
User Tokens.
User tokens
User tokens , or 'appcoins' as Naval Ravikant and Balaji Srinivasan have called them, are a form of digital currency needed to access the service provided by the distributed network.
As Union Square Venture managing partner Albert Wenger explains, you can think of these as tokens you buy at a fair to get on a ride.
In ethereum, for example, you need ether to build distributed apps on the platform. In the case of Sia, a distributed storage system, you need to own Siacoins to store files in the network.
User tokens are earned by providing value to these networks.
Contributions can take the form of mining, as in bitcoin, ethereum and Sia, or publishing stories, as in Steemit. Since user tokens are on a blockchain, they can be easily redeemed for any local or cryptocurrency.
Equity tokens
Equity tokens are used to finance the development of the network, but are not needed to access the services provided by the underlying protocol. As its name suggests, we can see 'equity tokens' as cryptographic shares of a network.
In exchange for investment, equity token holders are entitled to "dividends" in the form of revenue sharing or transaction fees in the network. For example, in the case of Sia, 3.9% of all successful storage payouts go to the holders of Siafunds, their equity token.
In many cases, these equity tokens represent shares of a distributed autonomous organization (DAO). A DAO's code is responsible for issuing the tokens, holding the money collected from the token sale, and contracting a company to develop the network.
Besides receiving a pro-rated reward, equity token holders in the form of DAO shares are usually entitled to pledge on proposals for how the investment money will be used.
That's the case of Digix, an asset-tokenisation platform built on ethereum. DGD token holders:
Receive a reward on the transaction fees of the Digix Gold Network
Are able to submit and vote proposals on the DigixDAO.
Debt Tokens
A third type of token is the 'debt token'.
We can see these as a 'short term loan' to the network, in exchange for an interest rate on the amount lent. Steemit is one of the few networks with debt tokens, issued in the form of Steem Dollars.
Steem, the cryptocurrency mined by the network, can be used to buy Steem Power or Steem Dollars. Holders of Steem Dollars receive a ~10% interest rate, paid in Steem Dollars.
Steem Dollars are unique to the economics of the Steemit protocol.
Through buying Steem Dollars, people can invest in the network with sufficient liquidity, without committing to the two-year vesting period to which Steem Power holders are subjected.
We see networks with multiple combinations.
These include networks with:
Both user and equity tokens (Sia, Digix)
Only user tokens (bitcoin, ethereum)
Only equity tokens (Golem, SingularDTV)
User, equity and debt tokens (Steemit).
