+## About
+
+Blockifier is a Rust implementation of the component in the Starknet sequencer that executes transactions, and is in charge of creating state diffs and blocks.
+
+## Roadmap
+
+The Blockifier is a step towards a decentralized sequencer client for Starknet, allowing anyone to run one.
+We'll add more milestones to this table once we finish the first one, where we blockify transactions sequentially, including all existing functionality.

+| Add the ability to execute a block and output a state diff.                                                                            |   ✅   |
+| Integrate with the existing Starknet Sequencer by replacing its current transaction-blockifying component, which is written in Python. |   ⏳   |
+| Implement optimistic concurrency of transaction execution.                                                                             |        |
+| Extend the Blockifier into a full Starknet sequencer, written in Rust, replacing the one currently in use.                             |        |
