blockchain technology is not only the underlying technology of bitcoin, but also the core and infrastructure of bitcoin bitcoin has been running without any centralized organization operation and management. Later, bitcoin technology was abstracted, which was called blockchain technology or distributed ledger technology
extended data:
disadvantages of blockchain technology applied to digital currency:
first, there is no circulation management organization for "decentralization" blockchain technology is essentially a distributed database system with one-way linked list logic structure and P2P network design mode, which determines that there is no unified central control system for virtual currency based on blockchain technology
Second, it is difficult to effectively control the quantity supply the circulation of virtual currency based on blockchain technology is fixed, and according to Fisher Equation, the total transaction volume of the whole society under a certain price level in a certain period has a certain proportion with the required nominal currency volume, while the constant currency volume obviously can not meet the requirements of the growing total price of social goods Thirdly, "mining mechanism" is difficult to create recognized value bitcoin itself has no value and no national credit support. Some people think that "by continuously consuming computing power and energy to inject value into virtual currency", but it is obviously not the most efficient choice to consume millions of calculations in order to find a hash value that meets the requirements Fourthly, procers and early holders are easy to get high seigniorage any virtual currency based on blockchain technology is held by a few people at the initial stage of its development. Take bitcoin as an example. At first, bitcoin was only a proct of a few people's game. The first bitcoin purchase in May 2010 was $10000 BTC's purchase of $25 pizza. The first bitcoin transaction completed in July of the same year was $0.04/btcSecond, grinding beads generally use leftover materials of large materials, or materials with more internal cracks, which are not suitable for making large pieces
Third, the current proction of Jasper is not small
so Jasper bucket beads are relatively cheap
