We asked @Austin_Federa of @doublezero about Multicast and how it works.
"Multicast is a technology most listeners have encountered in their day-to-day lives"
"It's a packet replication technology that sends data from one source to multiple destinations." 🦣
"The key thing about multicast is you can only do it on a private network—it doesn't work across the public internet."
"Applied to blockchain, if your validator builds a block, instead of sending it to 200 people or 2,000 nodes, you send it once, say 'Here's the block,' and every validator can receive it as the network automatically replicates the data to all needed destinations."
