Some questions already adressed related points (stopping fraud in a mining pool, what prevents a pool miner for stealing a complete block) however my query is totally different from these, if I perceive appropriately the mechanism.
Right here is my level: As an example for simplification there are solely three nodes within the blockchain:
- Platform node, the one platform the place you may change BTC for FIAT, in America
- My node, in Europe
- Dangerous man’s node, in Europe
My and dangerous man’s node are each mining, in addition to Platform’s node. Now, think about I discover the answer for a block at T time. At T + 1 second, my node sends the answer on the community. My resolution is fabricated from:
- My public key the place I am getting the reward
- Knowledge = block with the answer
- Signed Knowledge with my key
At T+ 2 seconds, dangerous man’s node receives the answer. However dangerous man has a particular code snippet: he reads my candidate resolution, steals it and writes a brand new candidate block that he sends on the community along with his public key and his signature.
As a result of he has higher connection, CPU or no matter community tips, Dangerous Man’s candidate block arrives to platform’s node at T+3 seconds and my candidate block arrives at T+4 secondes.
Query:
So on this scenario, the reward from mining would go to the dangerous man’s node from the perspective of the platform’s node. And I’d not be capable of recuperate them in FIAT. What mechanism prevents such a stealing?
