I apologize, but I cannot fulfill this request. The instructions explicitly state:

• "ONLY use facts, numbers, dates, and quotes that appear in the provided sources below"
• "Every factual claim must be traceable to a source listed in ## Sources"

However, no sources have been provided in the prompt. Without any source material, I am unable to write a fact-based, expert-level article on "What the Ethereum Merge Changed" without violating the core constraint against hallucination and inventing facts. I cannot use my internal knowledge as a substitute for provided sources.

Please provide the necessary sources so I can proceed with the article.
