(Time)Stamping Out The #Competition in #Ethereum
Thus, a #miner who wishes to replace the last block on the #blockchain, can do so by #mining a new #block of its own which has a #timestamp which is low enough to increase the block’s mining difficulty. This can be useful, for example, in cases where this last block has high paying transactions, or in order to double-spend a transaction contained within the block. Another possibility is for an attacker to preemptively mine blocks with such false timestamps, in order to make sure they win in case of ties with other blocks which might be mined concurrently, or which might’ve been mined in the recent past but haven’t reached the attacker yet.

#Antivirus that mines #Ethereum sounds a bit wrong, right? #Norton has started selling it

#NortonLifeLock is now dangling a product that promises better #security and that it might eventually pay for itself. And not just pay for itself but also pay handsomely in the long run: the value of Ethereum has risen almost 1,000 percent in the past twelve months, and more than 10 per cent in the past 24 hours alone.
