XDN Digitalnote will be a real financial instrument this year, implementing SWIFT messages types

in fact, XDN onchain messages is the very powerful tool for secure and private information transfer.
As you may know, there is a worldwide system called SWIFT (Society for Worldwide Interbank Financial Telecommunication). It provides a network to allow financial and non-financial institutions (e.g. corporates) to transfer financial transactions through a 'financial message'.
The majority of international interbank messages use the SWIFT network. DigitalNote will implement the SWIFT messages types on blockchain to be compatible with the existing SWIFT software.

We will make XDN be a leading social decentralized encrypted messages platform,
implementing desktop, web and mobile messages apps with the instant, free out-of-chain messages protected by proof-of-work and empowering the XDN blockchain.
Private, instant and decentralized information transfer is a global issue. The last US President election exposed that problem.
We are going to try to change the things and to solve that issue. We will introduce an absolutely new instant, free, out-of-chain messages that will empower XDN security. You will need to perform some proof-of-work to send a message for free (with no XDN fee). This message proof-of-work will be "added" to the global XDN proof-of-work securing the network. XDN will empower its financial instruments by social communication and will try to implement the real "people's money"

How exactly can the PoW required to send a swift like message be used to secure the Ducknote network? Isn't the whole point of PoW competing to solve blocks to process transactions? How can out of network PoW contribute if they're not trying to make a block?

1. SWIFT like messages will be onchain messages.
2. Social messaging platform will be based on out-of-chain messages (like we have self-destructed messages in XDN)
3. Are you familiar with Bitmessage? They use pretty the same technique against the network flooding. To send message you need to perform PoW. In our case this will be CryptoNight that will be used for additional XDN blockchain protection. In other words, to send the message, you will need to submit PoW. To be very clear: take your smartphone, launch the XDN messaging app, write a message, press the send button, wait a few seconds (doing PoW), Profit!
