 As mentioned payment channels can be announced to the network after they are established.
 This is happening via a peer to peer gossip protocol.
 After opening a channel a node will send out an announcement of the channel via the `channel_announcement` message to its peers.
-Every peer can validate the information from the `channel_announcement` message and verify that the funding transaction was indeed confirmed by the Bitcoin Network.

 Upon verification the node will forward the gossip message to its peers.

 Similarly nodes can be announced via the gossip protocol with the `node_announcment` message.
 For this message to be forwarded a node has to have at least one public channel that was announced on the gossip protocol.
-This again is a SPAM messure of the gossip protocol.
+This again is a spam measure of the gossip protocol.
 Payment channels have various meta data that are useful for other participants of the network to know.
 This meta data is mainly used for making routing decisions.
 As nodes might want to change the meta data of their channel once in a while this information is shared in a `channel_update` message.
-These messages will only be forwarded about 4 times per day for every channel to prevent SPAM.
-The gossip protocol also comes with a variety of queries and tools to initially synchronize a node with the view of the network or to update the nodes view after being offline for a time.

 We will investigate the details of the gossip protocol in a later chapter.
 For now it is only important to know that it exists and that it is used to share topology information of the Lightning Network with its participants.
 This topology information is crucually needed for delivering payments through the network of payment channels.
