Imagine a group project where everyone needs to agree on something before moving forward. Distributed consensus is a process where a bunch of computers in a network can reach an agreement on a specific issue, without needing a single person in charge to tell them what to do.
This is a crucial concept for blockchain technology, because it allows a network of computers to maintain a shared record of transactions (like a shared document for your group project) without needing a trusted third party (like a teacher) to verify everything. Different blockchains use different mechanisms to achieve distributed consensus, and DAGs are one option.
