Joseph Lubin, co-founder of Ethereum and founder of ConsenSys, announced on social media that the Ethereum blockchain is celebrating a decade of continuous operation as of July 30, 2025. Lubin highlighted the network's remarkable resilience, stating, > "Tomorrow we celebrate 10 years of uninterrupted uptime. And 10 years from now we will celebrate another 10 years of uninterrupted uptime. And so much more." This milestone underscores Ethereum's foundational stability in the rapidly evolving decentralized technology landscape.
Launched on July 30, 2015, with its genesis block, Ethereum was conceived by Vitalik Buterin as a programmable blockchain, expanding beyond simple cryptocurrency transactions to enable smart contracts and decentralized applications. Joseph Lubin played a pivotal role in the early development of Ethereum and subsequently established ConsenSys in 2015, a leading software production studio building tools and infrastructure for the Ethereum ecosystem.
Over its first decade, Ethereum has become the backbone of significant innovations, pioneering the decentralized finance (DeFi) sector and the non-fungible token (NFT) market. As of Q2 2025, Ethereum secures over $75 billion in DeFi across its ecosystem, enabling peer-to-peer lending, trading, and staking. The network also revolutionized digital ownership with NFTs, seeing trading volumes surge and attracting artists, game developers, and brands.
A critical evolution for the network was "The Merge" in September 2022, which transitioned Ethereum from an energy-intensive proof-of-work (PoW) consensus mechanism to a more sustainable proof-of-stake (PoS) system. This upgrade dramatically reduced Ethereum's energy consumption by 99.95%, addressing environmental concerns and positioning ETH as a more sustainable digital asset. Post-Merge upgrades like Shapella and Dencun have further optimized the network's performance and scalability.
Looking ahead, Ethereum continues to drive the Web3 movement, with ongoing developments in Layer-2 solutions like Optimism and Arbitrum aimed at enhancing scalability and reducing transaction fees. Joseph Lubin's optimistic outlook for another decade of uninterrupted uptime reflects the community's confidence in Ethereum's robust architecture and its potential to further revolutionize various industries through decentralized technologies. The network's consistent operation and continuous innovation solidify its position as a cornerstone of the decentralized internet.
