BCS Northampton: Blockchain Lecture

This evening I attended an interesting lecture on Blockchain at the University of Northampton, presented by Drs Ali Al-Sherbaz and Scott Turner. It covered the basics of blockchain, include hashing, mining, signing, creating blocks, and so on.

It then covered particular examples of blockchain projects within the University, including one on social interactions and one on network activity logging. Apparently Blockchain is one of the key topics the University will be addressing in its future development strategy.

What wasn’t covered, however, was Bitcoin and in general most comments were dismissive of cryptocurrency. I think that will prove to be shortsighted. Most of the criticisms and limitations levelled at Bitcoin and other cryptocurrencies during the event were demonstrably false or at least incomplete and a more detailed discussion would have demonstrated that.

Personally I think cryptocurrencies are here to stay, with Bitcoin taking the role of the reserve cryptocurrency, and their positions will get stronger and stronger over time. Whether they will eventually replace fiat currencies is less clear, but I certainly wouldn’t dismiss the possibility.

For sure they will massively disrupt the banking and financial sectors (see, for example, Bank Of America: Our ‘Inability To Adapt’ Could See A Failure To Compete With Crypto).

Cryptocurrency Mining at Home Heats Up With Eco-Friendly Miner

Proof of Work (PoW) mining operations, like Bitcoin and Ethereum, use a tremendous amount of energy and generate a tremendous amount of waste heat.

Qarnot is one of a number of growing companies that has found a way to turn that waste heat into controlled heating for the home or office.

The new Qarnot QC-1 “crypto heater” takes advantage of an obvious synergy: It makes use of the waste heat generated by mining crypto in the guise of an attractive space heater.

Spec wise, the QC-1 contains two GPUs: NITRO+ RADEON RX 580 8G 60 MH/s at 650W. Local electrical costs and climate are key determining factors with regard to recouping costs and making a profit; for example, if you are in a cold northern environment with cheap electricity like Quebec, then your costs to run it should be low enough (about $0.03 KWh USD) that the mining revenue should pay for the device in a few years.

The device mines Ethereum by default but can be configured to mine various other PoW-based cryptocurrencies such as Litecoin. A mobile app is available to monitor your account and configure the unit. The lack of fans or hard drives leads Qarnot to claim the system is “perfectly noiseless.”
