Bitmain is totally busted on its Monero miner scheme

Editor's Note

Earlier this week we covered the release of Bitmain's CryptoNight ASIC machines. CryptoNight is the memory-hard algorithm used by Monero and several other networks. The Monero community has expressed antipathy towards ASIC machines, because they are perceieved to enable the centralization of hashpower in what should be decentralized networks.

In February, Monero core developers announced that the network will be switching to a different mining algorithm in a few months. This means by the time the machines are shipped, they may not work on the "main" Monero chain.

Since this paradox started getting attention on Wednesday, March 14, Bitmain has reduced the X3 price from $12,000 to $3,000, making it look as if it had been caught red-handed.

Despite this sort of nonsense, the company is arguably an industry flagship, with a predominant role in the Bitcoin mining community, and its own multi-billion-dollar fork, Bitcoin Cash.

Some members speculated that Bitmain has started producing Monero ASIC miners a long time ago.

If confirmed, it could explain the rapid hike in hashrate in the past few months.

What’s new with BlockSci, Princeton’s blockchain analysis tool
(Arvind Narayanan)

"Today we’re happy to announce BlockSci 0.4.5, which has a large number of feature enhancements and bug fixes. As just one example, Bitcoin’s SegWit update introduces the concept of addresses that have different representations but are equivalent; tools such as are confused by this and return incorrect (or at least unexpected) values for the balance held by such addresses."

Why preventing a cryptocurrency exchange heist isn't good enough
(Patrick McCorry, Malte Moser and Syed Taha Ali)

"While this approach may be sufficient for conventional financial systems (where a centralized authority can – within certain limits – reverse transactions), it is clearly inadequate for the cryptocurrencies paradigm where damage can be done immediately and irreversibly. Instead, exchanges need to incorporate reactive mechanisms into their defense strategies that anticipate failure and allow them to recover after a successful attack."

"Besides, the goal of Antshare is to provide a smart platform for digitalized assets while Ethereum is a platform for decentralized applications. Assets versus applications is also a key difference between the two. Those reasons provide a 'no' to the question in the headline."

"Christopher Wylie, who worked with an academic at Cambridge University to obtain the data, told the Observer: 'We exploited Facebook to harvest millions of people’s profiles. And built models to exploit what we knew about them and target their inner demons. That was the basis that the entire company was built on.'"
