Issuing time of virtual currency DCR

1.

POW: full name of proof of work

pos: proof of stake

both of them are the consensus mechanism of blockchain and the bookkeeping method of digital currency

the difference is:

1. POW mechanism: workload proof mechanism, that is, the proof of workload, is the requirement that must be met when generating a new transaction information (that is, a new block) to be added to the blockchain. In the blockchain network based on workload proof mechanism, the ability of nodes to obtain the correct numerical solution to generate blocks by calculating the numerical solution of random hash hash is the specific performance of node computing power

POS mechanism: the proof of rights and interests requires the certifier to provide a certain amount of ownership of cryptocurrency. The operation mode of the proof of rights and interests mechanism is that when creating a new block, the miners need to create a "currency right" transaction, and the transaction will send some coins to the miners themselves according to the preset proportion. According to the proportion and time of token owned by each node, the equity proof mechanism reces the mining difficulty of nodes proportionally according to the algorithm, so as to speed up the speed of searching for random numbers

extended materials:

the concept of bitcoin was first proposed by Nakamoto in 2009. According to Nakamoto's ideas, the open source software and the P2P network on it were designed and released. Bitcoin is a kind of P2P digital currency. Point to point transmission means a decentralized payment system

unlike most currencies, bitcoin does not rely on specific currency institutions. It is generated by a large number of calculations based on specific algorithms. Bitcoin economy uses the distributed database composed of many nodes in the whole P2P network to confirm and record all transactions, and uses the design of cryptography to ensure the security of all aspects of currency circulation. The decentralized nature and algorithm of P2P can ensure that it is impossible to artificially manipulate the value of bitcoin through mass proction

3. Now it's very slow. I have all kinds of mining machines. Now dig DCR and Zec. Faster

4. The fire coin global station is scheled for the decred (DCR) recharge service at 13:00 Singapore time on June 14, 2017. At 11:00 on June 17, 2017, DCR cash withdrawal business was opened.

5. Sony is the leader of consumer electronics and one of the originators of digital cameras. In 1995, Sony and Panasonic developed a new DV digital camera. On July 24 of the same year, Sony took the lead in showing home DV and home digital video recorder in Japan, opening a new era of home digital video camera and announcing the birth of home digital camera, It has also become the number one digital camera instry. Although Sony has a large number of procts, the naming is still very standardized. In the home digital cameras, Sony generally uses the dcr-aabb format. The former part uses DCR, which means digital video camera recorder, that is, digital camera. AA represents series, such as TRV and HC series, and BB represents model number. Sony's digital camera series is not many, the first use is TRV series, horizontal model. For example, the early classic dcr-trv5, and the recent dcr-trv33e, dcr-tvd80e, etc. Since 200, Sony has replaced TRV series with new HC series, including dcr-hc15e, dcr-hc20e / 30e40e and dcr-hc85e. Sony also has the PC series of vertical models. The first dcr-pc11998, the original model of Sony's vertical machine, was released in 1998. Its net weight is only 460g, which is very light. This year, Sony released the middle end PC model dcr-pc109e, and the high-end PC series model dcr-pc350e, equipped with a CCD with a total pixel of 3 million, which has strong static shooting ability. In addition to the above series, Sony also has a small number of other models of digital cameras. The DVD series is dvdcam, that is, the digital video camera using DVD as the storage medium. It is also the new model released by Sony this year. At present, there are three models, dcr-dvd101e, dcr-dvd201e and dcr-dvd301e. The first two models have been sold in China. The other series is IP series. The body of this series of digital cameras is very small, and the smallest one is only the size of a playing card. It uses MMV format (micromv), such as dcr-ip1e. In addition to the above-mentioned, Sony's proct models also have a regional sales code. For example, the letter E in dcr-dvd 101e in the above body represents the procts sold in China. Other regions, such as Europe, have special sales codes, while the procts sold in Japan generally do not have any sales codes.
