Immutability and Network Security (The "Digital Rock")

Despite bugs that may arise in the software we use to access the #RedPacketMission (such as the recent Core case), the historical record of transactions (the #blockchain of $BTC ) remains the most secure computer system ever created. Thanks to its immense computing power (Proof-of-Work), altering the past or falsifying transactions is economically impossible. This mathematical certainty that "what happened, happened" is the foundation of its global trust.
