2017 really has been the year where hype in crypto, including financial hype and social hype in general has far exceeded the reality of what existing blockchain systems can offer. There is a lot of attention, and a lot of eager expectation, but as far as reality goes the practical usability of blockchains has in some cases even regressed due to rising transaction fees.

I expect 2018, at least within the Ethereum space that I’m best able to speak about, will be the year of action. It will be the year where all of the ideas around scalability, Plasma, proof-of-stake, and privacy that we have painstakingly worked on and refined over the last four years are finally going to turn into real, live working code that you can play around in a highly mature form in some cases on testnets, and in some key cases even on the public mainnet. Everyone in the Ethereum space recognizes that the world is watching, and we are ready to deliver.
 

Vitalik Buterin
Founder of Ethereum

Founded in 2015, the Fenbushi Capital fund with assets of $ 50 million was one of the first to provide seed investment to blockchain startups and participate in the ICO. During its existence, the fund invested in dozens of companies, which, of course, facilitated communication with the creator of Ethereum. 

Bitcoin Gold hit by Malicious Miner`s Double Spend Attack

An evil-minded miner efficiently made a double spend attack on the Bitcoin Gold network, making BTG at least the third altcoin to succumb to a network attack

Edward Iskra, Bitcoin Gold director of communications first admonished clients about the attack on May 18, reporting that an evil-minded miner was using the exploit to steal means from cryptocurrency exchanges.The miner bought at least 51 percent of the network’s total hashpower, which provided them with temporary control of the blockchain. Gaining this much hashpower is extremely expensive — even on a smaller network like bitcoin gold — but it may be monetized in tandem with a double spend attack.

The attacker, after getting the control of the network, started depositing BTG at crypto  exchanges while also intending to send those same coins to a wallet under their control. Generally, the blockchain would resolve this by including only the first transaction in the block, but the attacker managed to reverse transactions as they had majority control of the network.

As a result, they were able to invest funds on exchanges and withdraw them again soon, after which they repealed the initial transaction. This way they could send the coins they had primarily deposited to another wallet. 

An address of bitcoin gold connected with the attack has got more than 388,200 BTG since May 16 (basically from transactions it sent to itself). All of those transactions were associated with the double spend exploit, the attacker could have stolen as much as $18.6 million worth of funds from exchanges. The last transaction was sent on May 18, but the attacker could resume it if they still have access to enough hashpower to reach the control of the blockchain.

Bitcoin gold’s developers recommended exchanges to resist the attack by reaching the number of confirmations acquired before they lended deposits to client accounts. Blockchain data displays that the attacker reversed transactions as far back as 22 blocks, allowing developers to advise raising confirmation requirements to 50 blocks.
