"Finding a seam of gold after picking through rock" nghĩa là gì?

"Finding a seam of gold after picking through rock" -> nghĩa là 'đãi cát tìm vàng'.
Ví dụ
This is a race. Only one miner gets to mine a block, and that miner gets rewarded with Bitcoin. To mine a block is also to “mine” new coins—to pry (cạy nắp hộp) them out of the system after much computational (công việc trên máy tính) work, like finding a seam of gold after picking through rock. Hence the metaphor. When miners find the right number of zeros, they publish the block (số lớn cổ phần) and its hash to the Bitcoin network. Everyone else reviews the block and decides if it’s valid. (“Valid” means all the transactions (giao dịch) on the list are valid, the hash is correct, it has the right number of zeros, etc.) If they do, then they start work on the next block: They take the hash of the previous block, plus the transactions that have come in since then, plus a new nonce, and try to find a new hash. Each block builds on the one before.
