Green energy made useful for mining

Japanese energy operator Kumamoto uses excess energy to mine cryptocurrency
01 March 2018   1900

Kumamoto City local energy producer has reported it established an affiliate company OZ Mining that deals with the virtual currency. OZ Mining buys electricity from Kumamoto solar plants at a rate of 10~19 yen/kWh. The amount that the operator offers is a surplus of the produced electricity. This kind of application makes it effective to mine cryptocurrency.

Apart from just mining cryptocurrency, OZ Mining specializes in designing and building data centre sites (like mining farms) and assembles necessary mining rigs that can be fit to customer needs and power capabilities. Another notable product of the company is mining systems designed to work in cooperation to further increase the effectiveness.

The uncontrolled usage of electricity for the mining needs has recently become a mind-boggling issue. The situation has a reached a point when a solo mining farm easily overspends an entire country in terms of energy consumption. This poses a risk of huge pollution and environmental disaster. The instance of using a green energy is unprecedented and potentially could pave a way to more affordable renewable energy. Sources of renewable energy are usually located far from the population and pose a threat to the environment.

Developers to Combat Bitcoin Mining Cetralization 

Stratum V2 mining protocol will significantly change the principles of functioning of bitcoin mining

The mining company Braiins has provided instructions for using a code that can make the Bitcoin mining process more decentralized, CoinDesk writes. It is expected that Stratum V2 will significantly change the principles of functioning of bitcoin mining and will help increase the safety and efficiency of mining pools.

More comprehensive than BetterHash, individual job selection, zero time backend switching. If this protocol does everything it promises, "mining centralization" as an argument will be completely dead.

Matt Corallo of Square, who made a significant contribution to the development of the protocol:

This is huge for mining centralization. Instead of being focused on the centralization of pools (which is the world we're in today), we can focus on the centralization of actual miners [and] farm owners!

Bitcoin developer, Square

Last year, Corallo introduced the BetterHash protocol, which became his own plan for decentralization of mining. Now Braiins and Corallo decided to put their know-how together to present a more effective solution.

Individual miners often pool in order to smooth out the negative effect of the uneven distribution of rewards. This has led to the fact that today only three mining pools control over 50% of the computing power of bitcoin and can directly affect which transactions are included in the blocks.

To prevent this situation, Stratum V2 uses a model that changes the relationship of the miner with the mining pool. In the proposed system, the decision about which transactions to include in the blocks is made by miners, not pools. In addition, the individual right to vote in determining the vector for the development of bitcoin is returned to individual miners.

However, the developers note that mining pools interested in censoring transactions may simply refuse to install Stratum V2, and the problem of centralization consists in the production of equipment, which so far is concentrated in the hands of several large players.

To induce the use of Stratum V2 mining pools should the advantages offered by the protocol in the context of reducing costs, preventing attacks and limiting the possibility of theft of computing power. Now developers are completing the preparation of their solution, but it is already available for testing. It is expected that in the case of a favorable attitude of mining pools, their transition to Stratum V2 will require at least 12 months.
