## Header Syncing Protocols

Header syncing protocols are the mechanisms by which a blockchain maintains a copy of the block headers of another chain. By keeping track of the latest headers, a smart contract can verify proofs submitted by relayers at any given moment.

This is essential for cross-chain bridges that need to react quickly to events on the source chain. These protocols must be robust against chain reorganizations, ensuring that the system does not accept a header that is later orphaned.

Advanced syncing protocols use consensus-based verification to ensure that the headers represent the longest, most valid chain. This continuous synchronization is a high-bandwidth task that requires efficient data management.

It serves as the foundation for all subsequent cross-chain state verification and asset transfer logic.

## Glossary

### [Block Header Temporal Discrepancy](https://term.greeks.live/area/block-header-temporal-discrepancy/)

Latency ⎊ A block header temporal discrepancy occurs when the timestamp recorded in a block header deviates from the actual network-wide consensus time, often induced by propagation delays or miner clock skew.
