In 2015, the team issued a four-stage roadmap to implement a full platform. Two phases, Frontier and Homestead, were implemented. Phase III, Metropolis, is about to be released. This stage promises to be the most important upgrade yet, and is designed to make Ethium more secure and scalable, easier to use by non-technical users. The implementation of the city of Metropolis will require a difficult course that was to take place in late September, but was postponed twice. This is expected to be done on 17 October.
Metropolis will be launched in two steps, called Byzantium and Constantinople. Besanetium entered the testing phase on September 19, and despite some minor issues, it seems stable. The test successfully included the confirmation of knowledge manual zero, a completely unknown transaction between two parties. This type of transaction is very secure, that in theory it can not even penetrate by quantum computing.
The solid thorn, which is part of Byzantium, has been postponed on the advice of the founder of Vitriol Vitriol Ethium to give the miners more time to adopt it, enabling more testing. Butrin has reported that the etherium does not have difficulty, and that no further postponement will occur. Once the fork begins to block times will increase in steps from the current 23 seconds to 39, which will increase the difficulty for the miners, giving them an incentive to move to the new blockin.
Ethium upgrades are enthusiastically welcomed by cryptologists, and the prices of the ether are increased every time a major announcement is made. The value will almost certainly increase dramatically once the entire metropolis is implemented. If
upgrades continue to go smoothly, the etherium must be in a strong position for the foreseeable future.
Puterin and the development team were very straightforward about the need for Metropolis to be implemented without further delay. Ethium is rapidly growing in popularity among developers and organizations interested in exploring Blocchin technology. These include major corporations, national banks, and government institutions. In its current form, the network can not handle the demands that will soon be placed on it. Metropolis will play an important role in making the network more powerful and changeable.
Constantinople, the second part of the Metropolis, is expected to begin implementation in early 2018. Ethrium in the fourth major update, Serenity, will move the platform of evidence to the mining work to prove the share. The Ethium team has provided some details on how, or when, this transformation will take place.
