Claim 20:
21. A computer-implemented method to facilitate fast propagation of blockchain transactions over a network of interconnected nodes used to implement a blockchain, wherein a subset of the nodes are specialized network nodes interconnected by an overlay network, each specialized network node is not a full blockchain node and is configured to perform one or more dedicated functions or services, the method comprising:
receiving, at a specialized network node, an unconfirmed blockchain transaction;
validating the unconfirmed blockchain transaction; and
broadcasting the validated blockchain transaction to at least one other specialized network node;
wherein fast propagation is achieved as a result of using at least one of: (i) multicast to broadcast the unconfirmed blockchain transaction to the at least one other specialized network node and (ii) the specialized network node being permitted with a greater number of incoming and outgoing connections than are permitted for non-specialized network nodes.
