Ethereum cryptocurrency code is used, which means the following options:

Use of blockchain technology. The possibility of mining (using the proof-of-work protection method). The ability to create and use smart contracts.

The technology of blockchain proved itself as perhaps the safest way of keeping records of transactions performed within a certain society, each member of which owns a copy of the database distributed among members of the given society.

Blockchain - a chain built from the formed blocks with records of all transactions. A copy of the Blockchain chain or its part is simultaneously stored on multiple computers and synchronized according to the formal rules for constructing the chain of blocks. The information in the blocks is not encrypted and is available in clear form, but is protected from cryptographic changes through hash chains. Thus, the Blockchain database is distributed (decentralized) and cryptographically protected (https://en.m.wikipedia.org/wiki/Blockchain).

The possibility of mining, which gives the use of the methodology of protection against false data and fraud PoW, is by far the most widespread and reliable cryptocurrency in the environment.

A proof of work is a piece of data which is difficult (costly, time-consuming) to produce but easy for others to verify and which satisfies certain requirements. Producing a proof of work can be a random process with low probability so that a lot of trial and error is required on average before a valid proof of work is generated (https://en.bitcoin.it/wiki/Proof_of_work).

The minimum unit is 10^-4, or 0,0001 REC.

The conclusion of the block will occur every 20.5s (Similar to the Ethereum software environment, https://bitinfocharts.com/en/ethereum/ ). The block volume limit is 12 KBytes.
