👟 Why is reaching faster finality important?

Slow deterministic finality happens when you have to wait for enough blocks to confirm as valid on top of the block with the transaction, and it can take a while.

For PoS, the Aalborg upgrade solved the problem of slow finality using “Milestones.” With Milestones, block finality is established after a certain (variable) number of blocks, similar to architecture seen elsewhere in Ethereum.

Faster finality + fewer reorgs makes PoS more predictable. Because Milestones are configured at the dapp level, devs can configure this feature to their use case ✅
