Proof-of-stake is a method of maintaining integrity in a blockchain, ensuring users of a cryptocurrency can’t mint coins they didn’t earn. It is considered to be more energy efficient than Ethereum's current proof-of-work system.
- The Bellatrix upgrade will activate on the Beacon Chain on Sept. 6. This upgrade is responsible for setting the rest of the Merge process in motion.
- The activation is scheduled for epoch 144896 on the Beacon Chain, which should occur at around 11:34:47 UTC.
- After this, the Terminal Total Difficulty (TTD) value triggering the Merge will be 58,750,000,000,000,000,000,000. That TTD expected to be reached somewhere between Sept. 10 and Sept. 20. The Ethereum developers have hinted in past calls they are aiming for Sept. 15-16.
- During this period, the difficulty level will increase to the point where, eventually, proof-of-work crypto mining will no longer be possible.
- When TTD reaches 58,750,000,000,000,000,000,000, the network will merge its Execution layer with the new Consensus layer and transition to the new proof-of-stake consensus protocol.
