TechFlow News — On October 27, at the sixth Blockchain Global Summit held in Shanghai, Gavin Wood (Lin Jiawen), founder of Polkadot and Parity, delivered a keynote speech titled "2020: The Road to Polkadot Parachains" via video link, presenting updates on Substrate, Kusama, and the development of the Polkadot ecosystem.
He stated that Polkadot achieves universality through Substrate, enabling heterogeneous interoperability among parachains, with parallel transaction processing capable of reaching up to 100,000 TPS. Substrate is a modular blockchain framework supporting various foundational architectures, allowing efficient and low-cost creation of blockchains. These parachains can perform specialized tasks individually or be combined into integrated solutions.
Polkadot is a heterogeneous sharded network where each parachain can be highly customized to meet different use-case requirements. Parachains participate in the Polkadot network in a governed and upgradeable manner. Each parachain can process transactions in parallel, achieving up to 1,000 TPS individually. Currently, Polkadot supports around 100 parachains simultaneously, enabling a theoretical maximum throughput of 100,000 TPS—though actual throughput depends on transaction types. Parachains on Polkadot can either remain isolated or interact with one another, bridge to external networks, and rely on the relay chain for network security.
