A pivotal upgrade known as the Merge transitioned Ethereum from a proof-of-work (PoW) consensus mechanism to a proof-of-stake (PoS), causing a net supply decrease of 299,922.50 ether. The PoS mechanism needs users to hold ether to validate transactions and earn rewards. This eliminated much miner supply and made Ethereum more eco-friendly. However, despite these changes, ether’s market values have stagnated.

The Bitcoin network faces congestion and increased transaction fees due to the demand for BRC-20 tokens.

Ethereum is set to unveil a new testnet, Holesky, which promises larger capacity than its existing networks, Sepolia and Goerli. The new testnet aims to address potential scaling issues and accommodate more extensive testing for Ethereum’s growing developer community. Named after a Prague train station, Holesky’s significant size would provide a realistic environment for infrastructure and core protocol upgrade testing, targeting to enhance Ethereum’s resilience against unexpected obstacles.

“Manta Network has launched its zero-knowledge proof layer 2 scaling network, an innovative platform for ZK-enabled DApp development. This introduces increased throughput and reduced gas fees, promising future DApps realm expansion. However, challenges and regulatory issues, as highlighted by the Celsius incident, suggest the need for careful navigation in blockchain tech.”

Ethereum’s gas fees have hit an 8-month low due to low network activity, yet layer-2 scaling solution popularity is on the rise. This indicates the vital role of scaling solutions in maintaining low fees even amidst growing decentralization. Notably, Ethereum 2.0 and layer-2 solutions seem to alleviate the issue of high adoption against expensive gas fees and slow transaction times. Ethereum’s evolving technology is making it increasingly invincible, even against rival blockchain platforms.

Ethereum founder Vitalik Buterin underscored the risk of centralized models not fully safeguarding data.

“Ethereum’s shift from proof-of-work to proof-of-stake, known as the “Merge”, is viewed differently by stakeholders. While the move reduced Ethereum’s energy demands and is hailed as a ‘green’ shift, it overlooks the ongoing significant energy consumption from graphics processing units previously used in mining. Moreover, perspectives on security and profitability under the new system remain contentious.”
