3. According to the roadmap published on the official website, there are two major branches, one is the expansion of underlying functions, the other is the optimization of user experience. The underlying function expansion is mainly to develop new functions on the basis of peer-to-peer payment to support the long-term vision of a real Internet of value (IOV). For example, expand Op_ Return, optimizing the cache architecture for balance, anonymity on the chain, and native protocol component based on op code are designed to support the implementation of functionality
there are two main reasons why user experience optimization is listed separately. First, LBTC wants to build an excellent peer-to-peer e-cash system. Its basic idea is to put payment experience and user first, so it puts it at a high level, such as cross platform light wallet, accelerating payment confirmation speed, optimizing irreversible block mechanism, etc. Second, LBTC has always emphasized superior chain governance system. Before that, there was a standardized SGS (spark governance system) governance system, but it still needs to constantly improve the relevant mechanisms. For example, we should greatly optimize the node parameters and election mechanism, establish the LBTC foundation, multi-channel proposal process, and light wallet's support for the governance function on the chain.

Two dollars, especially US dollars

3. Currency symbol, that is, value symbol, refers to the currency symbol that replaces gold and silver as a means of circulation, that is, coins with insufficient value or notes without value

extended data:

there are many opinions about the origin of this symbol, among which the most common ones are

One view is that a narrow u is placed on a wide s in this symbol, which represents the United States. Another view is that it is the evolution of PS superposition. PS is the abbreviation of pesos, a kind of early round coin in the United States, which was used in the United States before the formal establishment of the mint in 1974. Later, the U.S. government recognized the dollar as a unit of the new currency, that is, one dollar. In writing, $$should be placed in front of the number. For example, 1 dollar should be written as $1, 50 dollars should be written as $50

In the mid-1960s, five years after the first dollar crisis, the United States expanded the war of aggression against Vietnam, and the balance of payments further deteriorated. In March 1968, the dollar crisis broke out, resulting in a serious second economic crisis. In more than half a month, the United States lost more than $1.4 billion in gold reserves. On March 14, 1963, the trading volume of London gold market reached a record number of 350-400 tons. In the face of such a situation, it is impossible for the gold general Treasury to cope with it

after negotiation, the member countries of the general gold pool (the United States, the United Kingdom, France, Switzerland, Germany, Italy, the Netherlands and Belgium, founded in October 1961) decided that the United States and the general gold pool can no longer supply gold on the free market at the official price of 35 US dollars and an ounce of gold, that is, they will no longer maintain the official price of gold, and the gold market will listen to its free rise. However, governments and central banks of all countries can still exchange gold with the United States in dollars according to the official price of gold, and there is no connection between the official price of gold and the price of gold in the free market, which is the so-called "double price system of gold"

at the same time, the United States has reached an informal "agreement on restraining gold withdrawal" with the former members of the general gold pool, and all countries have agreed not to exchange large amounts of gold with the United States in dollars in principle, so as to rece the pressure on the United States to cash in gold. This shows that the economic strength of the United States has fallen into a very weak situation (at the end of 1968, the proportion of the United States in the total gold of the western world has dropped to 25%)

5. US dollar
US dollar, also known as US dollar, is the official currency of the United States. Its emergence is e to the passage of the US Mint act in 1792. It is also widely used as a reserve currency in countries other than the United States. At present, the issue of US dollar is controlled by the Federal Reserve System of the United States. The most commonly used symbol for us dollar is "$", The ISO 4217 Standard Code for us dollar is USD.
currency name: United States dollar
