WHAT CHANGED
What the paper said, and what happened after.
Ten records. Each one keeps the design apart from the later network, the failure, or the thing that replaced it.
Terra
The peg was the design. The design failed.
Diem
A careful paper. Not a network.
Plasma
The exit needed the data.
Corda
A shared record for parties who already contract.
Interledger
Connectors, not a new chain.
Filecoin
Storage was proved. Retrieval was a market.
Helium
Coverage was not a customer.
Polkadot
Shared security, then a market for slots.
Cosmos
Sovereign chains fail on their own.
EOSIO
Speed from a short producer list.
