the glorious revolution. The king's name is William III and Mary II. Mary is the daughter of James II of the Stuart dynasty. William III was originally in power in the Netherlands. Mary's husband also has the blood of Stuart family. James II is a Catholic, trying to restore the status of Catholicism in England. When James II ascended the throne, he was very old. At that time, it was generally believed that his Protestant daughter would inherit the throne after James II died (when James had no son). The Whig party, which controlled the Parliament, thought that this would not affect the status of the Church of England, But later, James II united with the king of France to try to restore the status of Catholicism in Britain and the power of the king. At that time, Britain and France were hostile to each other, and Louis XIV's foreign expansion policy made the Netherlands, Britain and other countries united against France. James II's practice intensified the conflict between the king and the parliament. During this period, James II got a son in his old age, which made England under the leadership of a Catholic king in the future. Worried that it would harm the interests of Britain, Parliament planned to make Anne and William king of England. On the other hand, it was ring the so-called great alliance War (the nine-year war, see Cambridge Modern World History, omitted here) that William, the ruling Dutch, urgently needed the strength of Britain to help him fight against France, so that his plan could be carried out. James II fled to France and Ireland when he learned that the Parliament had given William the throne. With the support of France, he organized an army to attack the British army. Later, he was defeated in Ireland and fled to France. Later, the British Parliament passed a series of laws to consolidate this form. The British double king rule lasted until 1694 (Mary II died). In 1702, Anne, another daughter of James II, succeeded to the throne. After Anne died, the throne was transferred to Hanover, Germany, and the Stuart dynasty ended.

It is a P2P open source digital currency, which can be regarded as a branch of bitcoin. However, although lightcoin is based on bitcoin protocol, it does not require very high computing power. It can also be mined using ordinary computers. Lightcoin's algorithm comes from the algorithm designed by Dr Colin Percival for tarsnap secure online backup service (backup for Linux and other open source operating systems)
2. Namecoin
namecoin is also based on bitcoin, which is another branch of open source. Namecoin is a distributed DNS protocol -- generally speaking, it can transform the website name (such as ifeng. Com) that can be understood by human into the address that can be understood by machine. As its own DNS, this kind of currency can operate outside the normal Internet, so it can break away from the control of ICANN
the monetary value and domain name of namecoin are stored in the user's blockchain records, limiting the total number to 21 million
3. Peercoin
peercoin is a peer-to-peer variant of bitcoin, which can improve mining efficiency and security, and improve safeguard measures to avoid group mining. Now, group mining has been considered as a potential defect of bitcoin. According to the statistics of emerging currencies by coinmarketcap.com, peercoin currently ranks fourth in the market value of digital currencies
4. Primecoin
primecoin is a cryptocurrency similar to bitcoin, but it uses a completely independent mining algorithm. Bitcoin uses the hashcash algorithm, while prime coin uses the long Cunningham chains to create the value of money - a sequence of prime numbers named after mathematician AJC Cunningham

7, infinitech
published in June 2013. A by-proct of litecain. According to the mining situation and the total amount of money, infinite money can frequently adjust the mining difficulty ratio< Megacoin was only released in the fourth quarter of 2013, imitating bitcoin in the early stage. The total number of megacoin is limited to 42 million, which can be mined like other virtual currencies. Its biggest selling point is brand publicity, which other digital currencies lack< It was released in 2013 and is still in its infancy. In the security part of quarkcoin, nine independent loops are deployed and six different algorithms are used.
