> But on testnet4 every block yields 50 tBTC. So several people try to mine such a block, leading to the many parallel forks. What about lowering the coinbase block reward (with fees), if the difficulty was resetted? For example: if the real difficulty is equal to 1,000,000, and some CPU miner got 50.01 tBTC, then that miner could simply receive 5,001 satoshis instead. And the rest of the block reward can be just timelocked to the future block number, or simply burned (which is easier to implement). -- You received this message because you are subscribed to the Google Groups "Bitcoin Development Mailing List" group.
