Does Polkadot deliver what Ethereum promised?Ethereum’s consensus mechanism forces all nodes to validate all transactions. In contrast, the Polkadot blockchain breaks up batches of new transactions into many shards and processes them in parallel. The blockchains plugging into the network can have very different rules of operation, transaction processing and capabilities, giving the whole system much more flexibility.
