What is a bitcoin archival node?
Could you elaborate on what a Bitcoin archival node precisely is? In the realm of cryptocurrency and finance, the terminology often holds specific meanings. As a professional practitioner, I understand the significance of nodes in maintaining the blockchain, but I'm curious about the specific role and purpose of an archival node. Does it differ significantly from a regular node? Does it store the entire history of transactions on the Bitcoin network? How does it contribute to the security and stability of the Bitcoin network?
