Block 840000, mined on Friday night, marked a significant event in the blockchain industry as the block subsidy halved from 6.25 to 3.125. This pre-planned issuance schedule adjustment has historically posed challenges for miners but has also served as a medium-term bullish catalyst for Bitcoin (BTC).

In related news, the launch of a new protocol named Runes on the halving block sparked considerable hype and speculation. This resulted in a dramatic surge in transaction fees within the subsequent 24 hours.

On-chain movement fees skyrocketed to an unprecedented average of over US$128, setting a new record in the history of blockchain transactions. This event highlights the dynamic and ever-evolving nature of the blockchain industry, reinforcing an optimistic outlook for its future growth and development.
