Digital Banknotes

The main payment instrument in the SDN network

Storage of value
A digital banknote provides storage of value denominated in a digital currency issued in a given network.
Single use
Each banknote can only be used once. The payment process is the deactivation of the banknote on the side of the payer and the issuance of a new banknote on the side of the payee.
Single object
Digital banknote is a single digital object that contains all the necessary data for validation and making payments.
Operations with banknotes
Digital banknotes allow operations of division into parts (exchange) and combining several banknotes into one banknote of the corresponding denomination.

The concept of digital banknotes was born from our desire to make digital currencies as an instrument as familiar to users as ordinary cash

Digital Bills

User mistake protection tool

Exclusion of risks
The use of electronic digital accounts eliminates the risk of accidental loss of funds due to sending funds "to the void".
Purpose of a digital bill
The payment process consists in the redemption (deactivation) of the payer's banknote using the account details, which leads to the issuance of a new digital banknote on the side of the payee.
Digital bill
In order for the user of the SDN network to receive a payment using currencies issued in the SDN network, he must issue a unique digital invoice to the payer.

Here are incredibly many cases where people make mistakes and lose their money when making payments with cryptocurrencies. This happens to both ordinary people and professionals. Losing millions of dollars! We tried to minimize this risk and came up with electronic digital accounts.

Main ledger

Validation tool for digital banknotes and other assets in the SDN network

Data integrity
The data integrity of the main ledger of the SDN network is ensured by a non-linear non-block ledger which is the basis of GraphNet technology.
Local chains
Each node forms its own local chain of transactions, consisting of the transactions of its users and the transactions in which it acted as a validator.
Global linked chains
The main ledger is a collection of local chains, the elements of which are present in several local chains at the same time. This is called global linking.
The correctness of each transaction is certified by a dynamically formed group of nodes that form a pool of validators.
Building a pool of validators is a task that has a unique solution for a given electronic digital banknote and a given period of time.
Parallel processing
The non-block structure of the main registry provides the possibility of its parallel processing by an unlimited number of nodes.

Blockchain technology is an amazing creation of the human mind. But, unfortunately, the global block nature of such a registry is the main cause of scaling problems. And all attempts to fix this problem are nothing more than crutches. We decided that we needed to take into account all the best that is in the blockchain and build a new technology from scratch

Non-competitive consensus model in a decentralized network
This technology allows you to find nodes that, in terms of security priorities, should be notified first about a new transaction. Metarouting is the basis for solving the problem of double spending.
Reliability Metrics
With each transaction processed by a node, 50% of its reward is frozen in the network and comes to its disposal after the processed funds have come into motion. The volume of funds frozen is one of the reliability metrics.
Leading Nodes
The right of the node to process the transaction and include it in the general registry is determined solely by the user, based on the amount of the commission declared by the node and other parameters.

We inherited the competitive model from the world's first cryptocurrency «Bitcoin», which in itself is an incredibly beautiful technology. However, the competitive model of consensus leads to a competitive model of obtaining a service by users of the payment network. This is extremely unfriendly, and we decided to fix it
