It wouldn't be less secure as long as you adjust the confirmation accordingly. If we decided to mine one block every minute, then your usual 6 confirmation should become 60 confirmation. In the end, the same amount of work will have been done to prove the transaction is legit and so it's just as secure... Actually, one could argue since the average hash rate over 60 block is more accurate than over 6, it's actually more secure if you also pay attention to hash rate variation as part of the confirmation... That help in the scenario a very large pool goes dark to mine a sidechain. -- Thomas _______________________________________________ bitcoin-dev mailing list bitcoin-dev@lists.linuxfoundation.org https://lists.linuxfoundation.org/mailman/listinfo/bitcoin-dev
