Building a blockchain will require powerful hardware. When a new block is formed, the information is included in the general system, having undergone preliminary encryption using the cryptography method.
Blockchain is a digital accounting system. It stores information about transactions made using cryptocurrency. It is a public database where new information and algorithms are recorded in special blocks. They also form their own chain. This is how the blockchain is formed.
Today it will not be possible to create the required system without special equipment and software. The algorithm is used by some companies that perform such work on order. The project is implemented in three stages: research, development, production.
Stages of creation
If you decide to create a similar accounting system, decide how the block will look like. It consists of and:
- · From the index;
- Timestamp,
- · Data.
The chain contains strings of data that are prematurely encrypted using cryptography. In addition to the new block, encryption of the previous arrays is also required.
Information about the appearance of new arrays is added to the blockchain as follows: when a miner solves a block, he immediately adds it to the base. Within a hundredth of a second, information is transmitted to other participants in the system.
The very first array is required to create a blockchain. It is added manually or using a special program. For this, a function is written that adds genesis block. It contains an index, arbitrary data, and a hash of the last block. This makes it possible to create a function to add new algorithms. It is needed to accept the previous information on the network as the main parameter.
The peculiarity lies in the fact that when processing the previous information, the integrity and verifiability increases, which ensures the security of the data.
Safety and security
To protect the system from hackers and introduce false information at the time of creation, a unique description of the characteristics is added, also obtained using the encryption method. The system constantly checks the compliance of the parameters. Thanks to this, it is almost impossible to forge or swap arrays with information.
In addition to constantly checking all copies for compliance with each other, the system uses special protection techniques: PoW and PoS. Digital money holders have access to the source code, while other participants can only see hash sums.
The blockchain-based system is considered one of the most reliable. Cryptocurrency cannot be counterfeited or stolen. This is due to the fact that:
- All participants have an information base at once, and copies are constantly being automatically verified.
- The hash function is calculated using a special algorithm and has a time stamp. If someone manages to figure out the scheme, they will not be able to use it for their own purposes, since the timestamp will not match.
- All parts of the system are interconnected with themselves and cannot be changed.
In conclusion, we note that if you decide to grow the chain, you will need to significantly complicate the program with the addition of a server level. It will allow you to track changes in chains on many automated systems and limit the addition of blocks to a certain period of time.
