Ethereum/Polish zloty (ETH/PLN) taux
Ethereum is currently the second largest digital currency in terms of market capitalization, reaching in April 2018 a market cap worth 131 820 146 809 PLN. Although the cryptocurrency market in Poland is relatively young, and the Polish zloty is the currency of a nation with only 38.5 million citizens, the ETH/PLN exchange rate is the twelfth best pair on the Ethereum exchange market, ahead of the Russian ruble or British pounds. On March 2018, it retained its position in the top 30 digital currencies of the BitHub.pl ranking, despite decreasing tendencies of the majority of cryptocurrencies on the digital exchange markets. But what are Ethereum's development plans and what can the platform offer to its users?
Like most of new digital currencies based on blockchain technology, Ethereum solves the problems typical of outdated technologies, while optimizing its network in terms of transparency and speed of service for as many users as possible. However, it is not completely clear what limitations the platform may encounter in the coming years. An example of a problem is the limitation of the number of calculations in the block - the Ethereum blockchain currently supports about 15 transactions per second, which in comparison to Ripple (1,500, 24/7) or Visa (45,000), seems to be a small amount. The restrictions on the Ethereum network have caught the attention of developers and scientists who propose the implementation of more and more new systems to prevent both existing and potential problems. Although the creators of Ethereum insist that the flexible platform based on smart contracts differs significantly from Bitcoin (3-6 transactions per second), the principles of its scalability remain similar.
Like Bitcoin, Ethereum uses software that is as much as possible optimized to ensure that all digital content and their owners are registered in the general ledger without using central authority intervention. The main problem is that it becomes more and more difficult to maintain the balance when the number of users of the digital currency using ETH to buy coffee or invest in the Ethereum market is constantly increasing. In addition, a constantly growing number of decentralized applications, the so-called "dapps" (decentralized application) in the Ethereum network requires maintenance by nodes, which absorbs significant amounts of computational and energy resources. The network nodes of Ethereum platform are responsible for storing the entire transaction history in the blockchain, balances of user accounts and solving intelligent contracts. This task is not only responsible, but also not easy, because the total number of transactions increases every 12 seconds with the appearance of a new block.
One of the proposed solutions is a modern implementation of technology known as database sharding. Implementation of such technology would be based on dividing transactional data into subsets that could easily be handled by individual Ethereum network nodes. This eliminates the problem of "full" nodes, which has to store the full state of the network and the history of each transaction that took place. Instead, each node in such a scenario stores a subset of data and verifies only related to it transactions. If the node needs information about transactions or blocks it does not store, it immediately finds another node with the necessary data. The problem with this solution is about the fact that it is not a completely unreliable process, as is the case with the current functioning of the blockchain, and the decrease in network security could translate into a drop in the ETH rate and interest in Ethereum exchanges. The solution proposed by the creator and originator of the network, Vitalik Buterin, consists in the introduction of "cryptoeconomic incentives", paying rewards for appropriate accounting of transactions and punishing fraudsters, as is the case of Proof-of-Stake.
Much more ambitious technology are "off-chain" transactions inspired by Bitcoin's Lightning Network. Instant transactions outside of the chain are the closest to the original idea of the multilayered internet offer for upgrading the Ethereum network. They are not only extremely fast and almost unlimited, they allow users to pass an element of trust in any intermediary. Off-chain assumes that most transactions will be made on micropayment channels not related to the blockchain, reducing the network overload. This, in turn, should enable to launch the network node to the average user, which would have a positive impact not only on the Ethereum exchange market, but also an increase in Ether prices in countries where nodes have so far created only larger companies and organizations - including ETH/PLN rate.
Although investment in all kinds of digital currencies is associated with risk, because the market is constantly fluctuating, Ethereum is a currency which is worth watching, even for educational purposes. Although the Polish community associated with cryptocurrencies is primarily interested in altcoins, which shows popularity rankings from recent years, interest in the Ethereum course, the "forefather" of all altcoins remains one of the highest in the country. The average 24-hour volume of the ETH/PLN exchange was on April 2018 and it was around 1,200,000 PLN, which only confirms the established position of Ethereum on the digital currencies market.
