Bitcoin BEP2 (BTCB) is a stable digital currency issued by Binance that anchors the value of BTC (1 BTCB=1 BTC). Open and transparent issuance in accordance with the 100% margin system.

Project advantages

Freedom to Pay
Instantly send and receive any amount of money, anytime, anywhere. No bank holidays, no borders, no imposed restrictions. Bitcoin allows its users complete control over their funds.

Choose your own fee
There are currently no or minimal fees for processing Bitcoin payments. Users can include the transaction fee in the transaction to encourage faster transaction confirmation and receive transaction confirmation from the network faster. Alternatively, there are merchant processors that assist merchants in processing transactions, exchanging bitcoins for fiat currency on a daily basis and depositing funds directly into the merchant’s bank account. Because these services are based on Bitcoin, they can offer far lower fees than PayPal or credit card networks.

Reduces risk for merchants
Bitcoin transactions are secure, irrevocable, and contain no sensitive or personal information about customers. This avoids losses to merchants due to fraud or fraudulent chargebacks, and there is no need to comply with PCI standards. Merchants can also easily expand into new markets where credit cards are unavailable or where fraud rates are unacceptably high. The end result is lower fees, a larger market, and fewer administrative costs.

Security and Control
Bitcoin users are in full control of their transactions; merchants cannot enforce unwanted or undetectable fees that may occur with other payment methods. Paying with Bitcoin can eliminate the need to bind personal information to the transaction, which provides a great defense against identity theft. Bitcoin users can also protect their funds with backups and encryption.

Transparent and Neutral
All information about the Bitcoin funding itself is stored on the blockchain and can be verified and used by anyone in real time. No individual or organization can control or manipulate the Bitcoin protocol because its protocol is cryptographically secure. So we can trust Bitcoin to be completely neutral, transparent and predictable.

Proof of work

In order to implement a peer-to-peer timestamp server, we need to use a proof-of-work system like Adam Back's hash currency, rather than newspaper or newsgroup posts. Proof of work takes the search for a number such that when it is hashed, such as using SHA-256, the resulting hash value starts with several 0 bits. The average amount of work required grows exponentially with the 0 bits required and verification only requires one hash.

For our timestamp network. We implement proof-of-work by adding a random number to the block until a number is found that satisfies the required 0-bit hash of the block. Once a block satisfies the proof-of-work by expending CPU power, the block cannot be changed without redoing the work. Since later blocks are chained after this one, changing this block will require redoing all subsequent blocks.

Proof-of-work also solves the problem of determining how votes are voted in a majority decision. If the majority is voted by IP address, it can be corrupted by someone who can allocate a large number of IP addresses. Proof of Work is essentially per-CPU voting. The longest chain represents the majority decision, since the greatest computational proof-of-work effort is devoted to this chain. If the majority of CPU power is controlled by honest nodes, the honest chain will grow the fastest and surpass other competing chains. To modify a block in the past, the attacker must redo the proof-of-work of this block and all subsequent blocks to catch up with and exceed the work of honest nodes. We will show later that the probability of a slower attacker catching up to an honest node decreases exponentially as subsequent blocks are added.

In order to offset the increase in hardware computing speed and balance the interests of running nodes in different periods, the difficulty of proof of work will be determined by the moving average method to determine the average number of blocks generated per hour. If blocks are generated too quickly, the difficulty of generation increases.
