A. How many Coins are 1m of Dark Zone Breakout

1m of Dark Zone Breakout is 1 million Coins. 1k means one thousand, 1w means ten thousand, and 1m means one million. For example, 1MB of transport code is equivalent to 1 million KB. Currency is the product of commodity exchange. It is a commodity that is separated from the commodity world and serves as a fixed general equivalent in the process of commodity exchange. It is a kind of currency.

B. What is a Bitcoin fork?

The capacity of a block in Bitcoin is 1M (megabytes). And a transaction is between 250 and 500 bytes.

According to this algorithm, a block contains approximately 4 194.3 (transactions).

The confirmation time of a block in Bitcoin is 10 minutes, so the 7 transactions that a block can process per second may sometimes not even reach 7 transactions.

What consequences will this have?

Bitcoin’s forks are divided into hard forks and soft forks.

A hard fork means that when the block format or transaction format of Bitcoin changes, non-upgraded nodes refuse to verify the blocks produced by upgraded nodes.

Upgraded nodes can verify the blocks produced by non-upgraded nodes. Everyone continues the chain they think is correct, so it is divided into two chains.

What is a soft fork?

Soft fork refers to when the data structure of Bitcoin transactions changes.

Unupgraded nodes can verify the blocks produced by upgraded nodes.

< p>And upgraded nodes can also verify blocks produced by non-upgraded nodes.

C. One of the blockchain consensus mechanisms: POW proof-of-work mechanism

Blockchain can be understood as an immutable public ledger, in which all participants can verify transactions and Bookkeeping is a distributed ledger. So who will keep the accounts? How to ensure the consistency and accuracy of the ledger? That is, what is the consensus mechanism of the blockchain?

The consensus mechanism of the blockchain is to solve the problem of who will keep accounts (construct blocks) and how to maintain the consistency of the blockchain. There are many consensus mechanisms currently used in blockchain projects, such as: POW workload proof mechanism, POS equity proof mechanism, DPOS share authorization proof mechanism, etc. This article explains the POW workload proof mechanism.

The first successful application of blockchain is the POW proof-of-work mechanism adopted by the Bitcoin system. That is, taking the Bitcoin system as an example to illustrate the POW mechanism, first of all, the Bitcoin system has an incentive mechanism that allows all participants to compete for the right to bookkeeping, that is, whoever has the right to bookkeeping will receive the Bitcoin reward for constructing a new block (the current reward is 12.5 Bitcoin), and obtain the handling fees of all transactions in the new block as a reward.

How do participants compete for accounting rights? participants through themselvesThe computing power is used to calculate a mathematical problem. Whoever calculates the result first will have the right to keep accounts, and will also be rewarded for constructing new blocks. This mathematical problem is to find a random number Nonce so that the result of the hash calculation of the block header is less than the target value. The Nonce itself is a field in the block header, so by constantly trying the value of Nonce to satisfy the hash of the block header. It is hoped that the calculated result is less than the target value. By dynamically adjusting the target value, the difficulty of the calculated Nonce value can be adjusted.

The process of hash calculation Nonce is usually compared to a sieve throwing game. Based on the number of sieves participating in the game, the difficulty of the game can be adjusted by adjusting the number of sieve points thrown. For example: 100 people participate in throwing sieves, there are 100 sieves in total, and the required number of points is 100 to win, then whoever among the 100 people throws 100 points first is the winner, and has the right to keep accounts. If you find that everyone rolls 100 points too quickly, you can increase the difficulty and require a roll of 80 points to win. If another 100 people participate in the game, the number of sieves is increased in the game. For example, the number of sieves is increased to 200. The difficulty of the game is also adjusted by setting the number of throw points.

The sieve is similar to the computing power of the Bitcoin network, and the number of points thrown is similar to the dynamically adjustable target value of the Bitcoin network.

The longest chain in the blockchain is regarded as the correct chain. If two blocks appear at the same time, the two blocks will be temporarily recorded in parallel, and the subsequent blocks will be based on one of them. One block will form the longest chain as the consistent chain, and the other block will be discarded. Bitcoin is based on the confirmation of 6 blocks, so the discarded block will not receive Bitcoins. The reward of the system is a waste of computing power (electricity bill) competing for accounting rights. Based on workload incentives, participants must do their best to construct correct blocks, that is, to meet the consistency of the blockchain. That is, all users on the entire network can reach a unique and consistent public ledger.

At present, the computing power of the entire Bitcoin system has reached an astonishing 24.75EH/s, of which 1E=1000P, 1P=1000T, 1T=1000G, 1G=1000M, 1M=1000K, 1K=1000, H/s is one hash calculation (hash collision) per second, that is, 24.75E hash calculations are performed per second, and there is still continuous computing power added to the Bitcoin system. The competition for Bitcoin accounting rights involves hardware providing computing power from CPUs, GPUs, professional mining machines, and mining pools. At present, the stand-alone version of professional mining machines can no longer compete for accounting rights. Multiple mining machines must be combined into a mining pool to compete for accounting rights.

D. How much mh is 1th?

Bitcoin 1T computing power is a unit to measure computing power. The computing power is divided into units every thousand, and the minimum unit is H =1 time, 1000H=1K, 1000K=1M, 1000M=1G,1000G=1T, 1000T=1P, and 1000P=1E.

Computing power (also known as hash rate) is a measure of the processing power of a digital currency network. That is the speed at which the computer (CPU) calculates the output of the hash function. Blockchain networks must perform intensive mathematical and cryptography-related operations for security purposes. For example, when a network reaches a hash rate of 10Th/s, it means it can perform 10 trillion calculations per second.
