Blockchain as a Transport (BaaT)
Blockchain as a Transport (BaaT): BaaT leverages blockchain to create an architecture that can connect geographically dispersed Layer 2 islands over any available infrastructure, including the public Internet. As the resulting solution securely supports all kinds of traffic: Unicast, Multicast and Broadcast – BaaT will become the transport service of choice for all businesses.
Value Proposition of BaaT:
Because of seamless operation across the public Internet, BaaT is an appealing WAN transport option compared to traditional WAN technologies like VPN, MPLS, or expensive dedicated links.
BaaT is an advanced L2VPN solution for both enterprises and telco/service providers, with which the organization can leverage the public Internet for their WAN traffic so that they don’t need to share traffic with their upstream providers as in the case of MPLS VPN service or even modern SD-WAN.
Unlike other tunneling techniques, BaaT is built to operate in a multipoint fashion. Its signaling is done separately via the blockchain and it has no scalability issues.
BaaT can operate over any IP transport network including the global public Internet because no multicast underlay network is required.
No unknown unicast entry is to be found on any VTEPs; it’s either a unicast MAC address match, advertised over the blockchain, or a default entry toward the VXLAN gateway.
Multicast and broadcast traffic is handled via the head-end replication on the source VTEP to all other known VTEPs in the same VXLAN. The list of VTEPs is known – and always updated – over the blockchain.
