# Missed Messages and Recovery

<figure><img src="/files/5giVasckZpxrO0hPWGv3" alt=""><figcaption></figcaption></figure>

*New transaction broadcasts do not necessarily need to reach all nodes. As long as they reach many nodes, they will get into a block before long. Block broadcasts are also tolerant of dropped messages. If a node does not receive a block, it will request it when it receives the next block and realizes it missed one.*

\- Satoshi Nakamoto, Bitcoin Whitepaper

The network is designed to be resilient, allowing for the recovery from **missed messages**. New transaction broadcasts do not need to reach all nodes simultaneously; as long as they reach a sufficient number, they will eventually be included in a block.

#### Recovery Process

* If a node misses a block announcement, it will continue working on the chain tip it believes to be the longest.
* When a new block is announced that builds upon the missed block, the node can **quickly validate the headers and request any missing information**.

#### Importance of Robustness

* The network's tolerance for missed messages ensures that it can **continue to function effectively even in the face of communication failures**.
* **Nodes are incentivized** to improve their infrastructure to **minimize the risk of missed messages** which **reduces the delay of validating the previous block while it could already be initiating Proof-of-work on the new block.**
