However, from the perspective of market value, the scale of the DeFi world is still relatively small. Its value defined by the total locked-up value (TVL) as an indicator accounts for about 3% of the overall market value of the crypto field, while the market value of Ethereum only accounts for 7- 10%. In contrast, the market value of Bitcoin in 2020 will always hover around 60% of the entire crypto market. Therefore, the DeFi world has yet to introduce non-Ethereum native assets into the DeFi ecosystem to obtain greater value.
Bitcoin is different: it keeps going up and down the wall. No one really knows what happened, everyone is peddling something. People try to value it, but the result is either zero or infinity. Bitcoin is either a Ponzi scheme, a Dunning-Kruggerand, a purely speculative tool that doesn’t even have the luster of gold—or it’s gold, but it’s easier to hide, easier to trade, and therefore more valuable.
The Bitcoin system stipulates that starting from the genesis block, for every 210,000 blocks, the block reward is reduced by half, until the smallest unit of Bitcoin is 1 satoshi, which cannot be halved, and there is no more block reward. From block 0 to block 209999, there are exactly 210,000 blocks, and their block reward is 50 BTC. In other words: for blocks with a block height of 210,000 integer multiples, such as blocks with block heights of 420,000, 630,000, and 840,000, the Bitcoin system will perform a block halving operation.
For example, the Hong Kong dollar implements an issuance system linked to major international currencies. Before 1972, Hong Kong was a member of the British pound zone and the Hong Kong dollar was linked to the pound sterling. Therefore, note-issuing banks must deposit pound sterling or qualified collateral to the Monetary Authority in accordance with the prescribed ratio before issuing notes, and in exchange for interest-free certificates of indebtedness. On October 17, 1983, Hong Kong implemented a linked exchange rate linked to the U.S. dollar. When issuing Hong Kong dollars, note-issuing banks must deposit 100% of the U.S. dollar reserve at the exchange rate of 1 U.S. dollar to 8 Hong Kong dollars, and exchange it for the HKMA issued under the Exchange Fund account. Only the interest-free certificate of debt can be issued with equivalent Hong Kong banknotes. The Hong Kong Monetary Authority now manages the monetary policy in a unified manner, but it authorizes HSBC, Standard Chartered and banks to act as note-issuing banks. The note-issuing bank deposits the equivalent dollar value with the Monetary Authority. Although there is no interest income, its cash is mainly cashed to customers of its own bank, and This can improve reputation and derive more financial services, especially the provision of loans, etc., to derive more Hong Kong dollars and obtain better returns.
Alice holds the private key x, then chooses a random number r, and the origin G on the elliptic curve, calculates R:=r*G, public key X:=x*G, and uses the hash function to get a random number for VHow to start a Bitcoin walleterify the number e:=Hash(R,X,message), and then calculate s:=e*x+r.
