About Flashblocks

Flashblocks is a streaming layer that gives users near-instant UX while still running an explicit auction every 200ms. They achieve it by::

• Creating and streaming partial blocks every 200ms to other nodes.
• Providing users with early execution confirmations.
• Allowing nodes to incrementally download and continuously execute transactions rather than wait for new blocks.
• Calculating the state root and consensus once for multiple partial blocks, amortizing costly parts of block production.
• Serving early execution state over the existing, unmodified Ethereum JSON-RPC standard, enabling easy wallet and front end integration.

Test Transactions

In the transaction panel, you can submit test transactions to both networks and see the real-time difference in confirmation times between standard blocks and Flashblocks.
