A historic moment in blockchain history as the last block on Ethereum's original Proof of Work chain was mined.​ This marks the definitive end of an era that began with Ethereum's launch in 2015.​

The transition represents the culmination of years of development toward a more energy-efficient Proof of Stake consensus mechanism.​

Key points:

  • Final PoW block marks complete transition to PoS
  • Ends mining-based validation on Ethereum mainnet
  • Represents significant milestone in blockchain sustainability

This change fundamentally transforms how Ethereum secures its network and processes transactions.​

Last Proof-of-Work Ethereum Block

Last Proof-of-Work Ethereum Block

A significant milestone in Ethereum's history has been commemorated - the final proof-of-work block before the network's transition to proof-of-stake. This marks the end of an era in Ethereum's evolution, representing the last instance of traditional mining on the main Ethereum network. The transition, known as The Merge, fundamentally changed how the network validates transactions and creates new blocks. - Block was mined on September 14, 2022 - Represents the culmination of Ethereum's original consensus mechanism - Historical moment in cryptocurrency's technical evolution This block serves as a digital artifact of Ethereum's technological progression from energy-intensive mining to a more sustainable validation method.

Final Work on Ethereum PoW Chain

A significant milestone in Ethereum's history as the last piece of work was completed on the proof of work blockchain before the transition to proof of stake. This marks the end of an era for Ethereum mining and represents a pivotal moment in the network's evolution toward greater energy efficiency and scalability. The transition, known as The Merge, signifies Ethereum's commitment to reducing its environmental impact while maintaining network security and decentralization. - Last PoW block mined - Historical moment for Ethereum - Transition to PoS complete

Farewell Message on Ethereum PoW Chain

Farewell Message on Ethereum PoW Chain

A notable blockchain community member posted their final message on the proof of work Ethereum blockchain, marking the end of an era. The message simply stated 'gm and gg to @artonblockchain', following a tradition of 'gm' (good morning) posts that date back to 2022. This marks a significant transition point as Ethereum has fully embraced its proof of stake consensus mechanism. - Previous related posts included similar 'gm' messages dating back to October 2024 - The simple yet meaningful gesture represents a cultural touchstone in the Ethereum community *Historical context: 'gm' became a crypto-native greeting symbolizing community connection*
