Which currency is BTC or BCC

1.

They are:

bitcoin

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

bitcoin cash

bitcoin cash is a new version of bitcoin with different configurations launched by a small number of bitcoin developers

extended data:

virtual currency refers to non real currency. Well known virtual currency, such as network company's network currency, Tencent company's Q currency, Q point, Shanda company's voucher, Sina's Micro currency (used for micro games, Sina reading, etc.), chivalrous Yuanbao (used for chivalrous road game), silver pattern (used for bixue Qingtian game)

the popular digital currencies in 2013 are bitcoin, Leyte coin, infinite coin, quark coin, zeta coin, BBQ coin, pennies (Internet), invisible gold bar, red coin and prime currency. At present, hundreds of digital currencies are issued all over the world. Popular in the circle & quot; The legend of "bitcoin, Wright silver, infinite copper, pennies aluminum"

2. BCC started mining at 20:00 on August 1, and separated from bitcoin's main chain in block 478559. Viabtc, China's mining pool, excavated the first BCC block, and then the next block 478560. Before the separation from the main chain, the data stored in the blockchain and the running software are compatible with all bitcoin nodes. After the separation from the main chain, it begins to execute new code and package large blocks. Thus, a new BCC blockchain is born, and BCC also begins to develop independently

at present, the BCC network has become stable, the block speed is basically close to an average of 10 minutes, and the computing power of the whole network is basically stable at 5% - 10% of that of bitcoin

generally, it is through mining or direct purchase on the trading platform!

3. Bitcoin cash is a new version of bitcoin with different configurations launched by a small number of bitcoin developers. At 20:20 on August 1, 2017, bitcoin cash began to mine, and the same amount of bitcoin cash (BCC) will appear in each bitcoin investor's account. It can be purchased on the trading platform or mined like bitcoin

4. Bitcoin cash (BCC), in English, is a new type of blockchain asset proced by a hard bifurcation of bitcoin. It is a decentralized digital currency supported by a community of large block supporters. BCC removes segwit, cancels the limitation of 1m block size, supports 8m block size at most, and adheres to the expansion route on the chain. The purpose is to better realize the "point-to-point encrypted e-cash system" described in Nakamoto's white paper. At present, many foreign exchanges have launched BCC trading. It's in line with bitcoin.

5. BCC is not a bifurcated currency. BCC is a new type of blockchain asset based on the original bitcoin chain
BCC does not meet the definition of bitcoin network bifurcation. BTC and BCC are two completely different chains in two days. As like as two peas, the whole network as like as two peas, which can not be synchronized in one chain, has two pieces of block chain network with identical bitcoins. Two networks have a large number of miners digging, and transactions on two different networks can not be synchronized. This leads to two even the same difficulty of two parallel chains, which is called forking.
BCC has also been identified by bitcoin international Roundtable forum as a competitive currency that replicates bitcoin blockchain and modifies some codes. Therefore, it is a wrong interpretation that BCC is the network fork of bitcoin.

6. The differences between BCC and BTC are as follows:
BCC: the isolation verification is removed, the 1m block chain size limit is removed, the on chain expansion route is adopted, and the idea of large block is adhered to
BTC: isolation verification is adopted, 1m block belt line remains unchanged, lightning network is adopted, and small block concept is adhered to!

7. Pro test is not bad, at least people can watch it for free, and there are not so many annoying advertisements.

There must be some worries when using face recognition, which mainly comes from two aspects: the first is the reliability of face recognition technology, and the second is the security of face recognition technology. Now I will talk about the disadvantages and worries of today's face recognition technology from these two aspects

to sum up, based on the safety and reliability of face recognition technology, I am still worried about face recognition
