Opal (OPAL) is a cryptocurrency designed for use in the virtual world. It was created to bring greater transparency and convenience to the buying and selling of goods, services, and property on the internet. It is a decentralized, peer-to-peer network that eliminates third-party transaction fees and has the potential to dramatically reduce the cost of online transactions. Opal was founded in 2013 by a group of computer scientists and entrepreneurs. The founders had a vision to build a secure and open payment network that would empower everyone to access digital money and services with minimal fees and maximum transparency. The team has since grown to include a number of cryptocurrency specialists, developers, and even a Virtual Reality engineer. What makes Opal unique is its usage of the PoS (Proof-of-Stake) consensus mechanism. Unlike traditional cryptocurrencies that use Proof-of-Work (PoW) to confirm transactions, PoS functions by rewarding holders of the currency for helping to maintain the network. This incentivizes users to store their funds in the currency and makes it more difficult for attackers to mount an attack. Another great aspect of Opal is its focus on usability. The currency is designed to be accessible and easy to use for both novice and experienced users. It is also the first cryptocurrency to use the virtual reality platform Oculus to provide an in-depth tutorial and enhanced user experience. Opal can be used to buy and sell goods, services, and virtual assets on sites like eBay and Amazon, as well as decentralized marketplaces such as Openbazaar. It can also be used for remittances, payments for goods and services, and any other need where digital payments are necessary. The currency is can be purchased on multiple cryptocurrency exchanges, including Bittrex, Livecoin, and most recently on Coinbase. It can also be bought and sold on peer-to-peer marketplaces such as LocalOpal and OpalTrade. Overall, Opal is a great option for anyone seeking to transact on the web with low fees and a high degree of security and transparency. The cryptocurrency has a clear use case and is user-friendly, making it an ideal choice for those looking for an easy way to make payments online.
