Blockchains prevent private WANs.
Any Party Communications
Blockchain technology continues to search for a problem that it can uniquely solve and be monetised. Cryptocurrencies like Ethereum & Bitcoin are niche use cases with modest success but more interesting is the potential for blockchain for B2B transactions e.g. invoices, purchases orders, and boring stuff like that.
An underlying assumption in blockchain technology is that any node in the blockchain system is peer-to-peer connected network.
Thats not a private WAN using MPLS.
Blockchain will demand a public WAN thats always available to all participants at low cost. Each party in the blockchain must connect to the same network.
The EtherealMind View
In the past 30 or so years, I’ve worked on private B2B networks for interparty financial transactions. Its was acceptable to wait three to six months for a private WAN deployment.
No one is going to deploy a Private WAN while the Public WAN (Internet) exists, is cheap, and already deployed everywhere.
If blockchain technology get traction, it will be a business driver to move away from Private WAN and further shrinking the profits of the carriers.
