BCC blockchain
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!
BCC mining and bitcoin mining are the same, the only difference is the dynamic mining strategy
when BCC was just born, it continued the mining difficulty of BTC. The miners lost money for mining out of belief. At the beginning of bitcoin's birth, they even proced a block within 12 hours. In order to ensure the stable development of BCC network, BCC adopted the strategy of dynamic adjustment of mining difficulty, which can ensure that the block speed of BCC can well adapt to the decline of computing power
BTC is a difficulty adjustment for every 2016 blocks, while BCC adds a rule of "if the MTP interval of the past six blocks is greater than 12 hours, the next difficulty will be reced by 20%". At present, the mining difficulty of BCC has been reced a lot, which is about 13% of that of BTC. BCC's current block speed is close to an average of 10 minutes out of a block
mining principle of BCC:
the previous life of BCC was bitcoin. Before the bifurcation, the data stored in the blockchain and the running software were compatible with all bitcoin nodes. After the moment of bifurcation, it began to execute new code and package large blocks, thus forming a hard bifurcation on the chain. At present, BCC is still a futures, which will be officially split into a new currency on August 1
security problems faced by bitcoin:
the first security threat of users comes from the user activated hard fork or uahf - all BTC holders who control their private key get an equal number of BCCs at the time of fork
that's the problem: there are many domestic trading platforms designed for bitcoin, but it should be noted that many investors use third-party transactions or unsupported software wallets, but the investors themselves do not control their private keys, so it is the third-party trading platform that finally receives the new currency. Some platforms will inform customers, while others will not
many investors have transferred their assets to the supported bitcoin wallet a few hours before the hard fork, while investors without independent wallets have to wait
there are many opportunities for phishing attacks or other malicious attacks, especially considering that most successful malicious attacks against bitcoin are focused on controlling private key or hacker exchange, rather than directly attacking currency. About the security of bitcoin, you can also add your own wechat seciot to communicate
BCC is very similar to BTC in technology, adding greater blocking and transaction replay protection, and the latter is in a new form of signature. Bitcoin cash transactions use a new sight_ Fork ID, which prevents bitcoin cash transactions from being replayed on bitcoin blocks
the new hash signature also brings additional benefits, such as the input value signature improves the security of hardware wallet and eliminates the second hash problem. In short, it is theoretically safer than BTC, and its purpose is to start and use faster and more convenient
However, BCC does face a major threat, that is, most attacks, that is, the security risk of a single entity acquiring more than 51% of the network processing power. At the same time, the common enemy shared by the two blockchains is interrupt attack. Most attackers use network interrupt to split the network to improve the probability of successat the same time, partition network and network delay attack are threats. According to the latest research paper, for the so-called distributed network, it is easier than assumed, and 20% of bitcoin nodes are hosted in less than 100 IP prefixes
BCC does not conform to 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.

BCC started mining at 20:00 on August 1, and separated from the bitcoin main chain in block 478559. The first BCC block was excavated in viabtc, the Chinese ore pool, and then the next block 478560 was excavated. 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.
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!
after BCC successfully separated from the main chain of bitcoin on August 1, it has gone on an independent development road and is regarded as a strong competitor of bitcoin in the community.
