Mining Pool BTC.Top Briefly Controls Over 51% of Bitcoin Cash's Hashrate

BTC.Top, a popular cryptocurrency mining pool, has recently hit a high of 54% of Bitcoin Cash’s hashrate, before seeing it recede. According to some users the mining pool has just been going after profitability, although any pool having over 51% of the hashrate could be cause for concern.

According to data from Coin.Dance, BTC.Top managed to mine over 54% of the blocks on the Bitcoin Cash network for a brief period of time, before seeing its hashrate go down. At press time, data shows in the last 24-hour period it mined 47% of blocks on the network.

Having over 51% of a network’s hashrate is seen as negative by many, as it could allow the entity controlling the majority of, in this case Bitcoin Cash’s hashrate, to pull an attack on the blockchain and double-spend coins.

This essentially means every network participant is forced to trust the mining pool not to attack Bitcoin Cash. Notably, BTC.Top is believed to have recently thwarted an attack on the network that sought to steal coins someone sent to a Segregated Witness (SegWit) address on the Bitcoin blockchain.

As such, network participants seemingly trust the mining pool was only mining the most profitable cryptocurrency on the SHA-256 algorithm, and wasn’t trying to act maliciously. This, however, doesn’t mean it couldn’t.

Various cryptocurrencies have suffered 51% attacks in the crypto space’s short history, including Verge (XVG), Bitcoin Gold (BTG), and Ethereum Classic (ETC). ETC suffered one of the most notable attacks, as hackers compromised one of the most popular networks in the space to double-spend coins worth over $1.1 million.

While BTC.Top heavily mines Bitcoin Cash, it revealed back in November of last year, before the hard fork that created Bitcoin Satoshi’s Vision (BSV) occurred, that it was apolitical and would support the blockchain with the most hahspower.

At the time Jiang Zhouer, the Chinese cryptocurrency mining pool’s founder, revealed BTC.Top’s goal was to recover stability for Bitcoin Cash, which at the time was engaged in a “war” between two sides.

On BSV’s side there are also concerns about a potential 51% attack. As covered, CoinGeek has reached the necessary hashrate to attack the network more than once, but hasn’t done anything malicious.

Dubai-Based Real Estate Giant Aiming to Launch Token on JPMorgan’s Quorum

Dubai-based real estate developer Emaar Properties says that it plans to launch this year a blockchain-based referral and loyalty platform called EMR that is being built on Quorum, JPMorgan Chase's enterprise-focused fork of Ethereum.

Emmar Properties is one of the world's leading real estate development companies. Its best-known project is Burj Khalifa, which is the world's tallest building. This is a skyscraper in Dubai, United Arab Emirates (UAE) that has a roof height (i.e. total height - the height of the antenna) of 828 m (2,716 ft ).

According to a report published on October 17 by local media outlet ArabianBusiness.com, the EMR platform rewards Emmar's customers with EMR tokens. Emmar says that these tokens "will not only be redeemable in Emaar’s real estate, hotels, ecommerce operations and malls, but can also be traded with other users."

Emmar Chairman Mohamed Alabbar had this to say:

We didn’t become Emaar by standing still, or by thinking small. By launching the EMR utility token ecosystem, Emaar is expanding the concept of connection. We aren’t just looking into the future — we are building it.

It will be possible for customers to use a mobile app (available for iOS and Android) to "access the referral and loyalty system and earn or redeem EMR tokens."

Hadi Kabalan, director of tokenisation at Emaar, stated:

We have an existing ecosystem and a large customer base, as well as millions of further potential users globally who have yet to discover Emaar. Our blockchain token platform positions us to grow our user engagement with today’s digital-native, mobile-first generation who expect a fairer internet and want to be part of the conversation.

For those of you who have not come across Quorum before, here is how a member of the Quorum team described the project in a reply to a Reddit post in November 2018:

"Quorum is a fork of the go-ethereum (geth) client with a few updates that add enterprise level features such as supporting private txns, node permissioning, fast consensus algorithms, block finality, and some others. It was originally created through a joint effort by JPMorgan and core engineers from the Ethereum Foundation. Beyond that, it has advanced to keep up with geth releases and has a full time team dedicated to it and its sub projects... Quorum does not have a mainnet, and the expectation is that users of it set up their own network, be it private or otherwise (we are aware of several that are public)."
