New friendly protocol to solve the problems of scalability and high transactions costs in Ethereum network. The upgrade means more decentralization, functionality and competitiveness to the system.

On May 8, developers released a planned improvement to Ethereum’s network – a new version of the code of Casper. Hybrid Casper Friendly Finality Gadget was introduced to move network away from mining-related problems, as “excessive energy consumption, issues with equal access to mining hardware, mining pool centralization, and an emerging market of ASICs”, the ultimate goal being to move the network from a PoW to a PoS system.

Let’s see what is known about “possibly the most significant” change to the network to date, according to Ethereum News.

Energy consumption and commissions

While 2017 was exciting due to the exponential price speculation of cryptocurrencies, it emerged that neither Bitcoin nor Ether in their present form would be able to become a fully fledged alternative to fiat currencies because of their very low transaction speeds.

An additional concern was the high amount of energy required to mine leading cryptocurrencies. Therefore, it should come as no surprise that among journalists and analysts, the latest trend has been comparing mining costs to the rate of the energy consumption in each country to determine where mining would be most profitable.

To date, developers of leading cryptocurrencies have failed to solve the issues related to scalability. In particular, Ethereum scales poorly despite a huge number of miners. Hypothetically, it may seem that as more people mine the cryptocurrency, the more transactions the network can handle. The reality is that as all these miners simultaneously try to process one block, the complexity of production increases and the network bandwidth remains the same. This means that even if the number of miners grows a thousand times, one block will still be produced in ten seconds and the cost of electricity would noticeably increase.

A direct consequence of poor scalability is high commissions. Miners choose transactions with a
