Costa Dorada - mecca for tourists in Spain

  The Spanish Costa Dorada stretches southwest from Barcelona to Tarragona on the east coast. With beautiful sandy beaches next to the mountains, quaint villages and coastal towns, the Costa Dorada is a popular tourist choice for holidays all year round. Families gather here not only because of the wonderful climate and magnificent sandy beaches, but also because of the many attractions. The Costa Dorada has the resorts of Salou and La Pineda, Salou forms an eight-kilometer continuous resort. This stretch of the Mediterranean has beautiful sandy beaches that are ideal for sunbathing, swimming, and a wide range of water sports. The whole family will be happy to take a trip to the Aquopolis water park in La Pineda, and the most famous Spanish theme park, Universal PortAventura. Aquopolis Water Park is on the outskirts of La Pineda and is a great place to cool off when the weather is at its peak. You will even get the chance to swim with the sea lions in the park. The Universal Port A...

Cryptocurrencies that work on the PoW algorithm

 Cryptocurrencies that work on the PoW algorithm

Proof-of-Work is used in most well-known cryptocurrencies, including:

Bitcoin. This is the very first and most demanded cryptocurrency that uses the PoW algorithm from the very beginning (since 2008).
Litecoin is a well-known fork of Bitcoin, which allows you to double the processing speed of blocks than in the BTC network. Litecoin is the first network to convert cryptocurrencies.
Ethereum is a cryptocurrency that was the first to offer the community smart contracts to automate various processes and create applications. Today, Ethereum uses a hybrid Casper algorithm, and in the future, developers want to completely abandon the PoW algorithm. This is due to the fact that Vitalik Buterin originally intended to use PoS, but the algorithm had problems that forced the developers to turn to more proven mechanisms. Now Buterin hopes that the Casper protocol he created will solve the actual problems of the PoS algorithm and will be able to completely prevent the possibility of forks, which will allow him to get away from Proof-of-Work in the future.
DASH is a promising cryptocurrency that provides completely anonymous payments. Today, the number of DASH transactions exceeds 1% of the total. DASH mining is based on the X11 hashing algorithm. This is an upgraded version of PoW that has resulted in higher system utilization. As a result, the popularity of the network grows, the complexity of mining and the rate of cryptocurrency increase.
Quark is an experimental cryptocurrency that can be mined on CPU processors. Initially, transactions on the network were confirmed every 30 minutes. The uncontrolled release of coins attracted the attention of users, which is why the number of miners increased. Light mining led to the fact that in the first 6 months of the project's existence, users mined almost 200 million coins. The developers had to reduce the issue to 1 million Quark per year.
Monero is an anonymous payment platform. The developers transferred the cryptocurrency to the new PoW CryptoNight consensus algorithm. This happened because 85% of the total network hashrate is generated by FPGA and ASIC devices. The hashrate of one such device is about 128 Kh/s, while the mining farm of 6 video cards barely reaches 6-12 Kh/s. This calls into question the decentralization of the network and contradicts the principles that are at the heart of Monero.
