Finding a valid proof of work allows a miner to propose a block, but full nodes independently determine whether that block follows Bitcoin's consensus rules.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eWhat does Bitcoin's difficulty adjustment do?\u003c\/strong\u003e\u003cbr\u003e\nBitcoin periodically adjusts the mining target so that block production remains near its long-term target pace despite changes in total mining power. A higher difficulty makes finding a qualifying hash harder, while a lower difficulty makes it easier.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eHow does proof of work help protect Bitcoin's history?\u003c\/strong\u003e\u003cbr\u003e\nEach valid block adds proof of work to the chain. Replacing previously confirmed history would require producing enough competing work to overtake the valid chain with the greatest cumulative proof of work, making deeper rewrites progressively more costly.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eHow long will my order take to arrive?\u003c\/strong\u003e\u003cbr\u003e\nEach item is made to order. Production typically takes 2-5 business days, followed by 4-8 business days for shipping. The estimated total delivery time is 6-13 business days.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eWhat if my Mouse Pad arrives damaged, defective, misprinted, or incorrect?\u003c\/strong\u003e\u003cbr\u003e\nDamaged, defective, misprinted, or incorrect items can be evaluated for replacement.
