The top five blockchains saw more than 1,000 pieces of code added, an increase of 12.4 percent week-over-week.
Layer 2 Arbitrum and Optimism innovations drove much of the weekly level of development and continued work on system enhancements.
Cardano, Cosmos Hub, and Stellar resumed maintenance, with a focus on infrastructure, suggesting long-term thinking and aggressive protocol development.
The blockchain development ecosystem is experiencing a backend scramble, with the top five networks collectively notching more than 1,000 weekly code commits. According to recently monitored developer metrics, these platforms—Arbitrum (ARB), Cardano (ADA), Cosmos Hub (ATOM), Optimism (OP), and Stellar (XLM)—collectively witnessed a 12.4% rise in weekly development contributions, signaling an aggressive push for ecosystem upgrades, feature launches, and protocol updates.
This level of developer activity shows a broadening trend where blockchain building is gaining momentum despite broader crypto market volatility. While token prices have been volatile over the past few weeks, builder activity on such platforms is remaining stable and in some cases increasing significantly. Such chains are the most heavily built, with new code continuously being committed to improve network functionality, governance features, and user experience features.
Arbitrum and Optimism Continue to Dominate Layer 2 Development
Arbitrum, which is considered the top Ethereum Layer 2 network, as well as Optimism, have posted impressive growth rates in the last seven days. The two platforms are still undergoing improvements to enhance scalability, reduce transaction expenses, and accommodating accelerated settlements. This is represented by the top spots in commit rankings and points to a larger movement towards Layer 2 deployments as Ethereum scaling becomes an urgent goal in the context of the decentralized ecosystem.
Cardano and Cosmos Hub Deliver Groundbreaking Infrastructure Updates
Cardano and Cosmos Hub have both enjoyed an active faucet of development work, with weekly commits pointing to internal updates to on-chain governance and cross-chain interoperability. Cosmos, which is commonly referred to as its interchain architecture, continues to commit to modular system updates, and Cardano is in the stages of its roadmap targeting smart contracts and decentralization. Their regular developer presence has meant that both networks have been part of the debate on long-term strategy in blockchain infrastructure.
Stellar Sees Innovative Enhancements as Cross-Border Utility Expands
Stellar, which was commonly linked to cross-border payments and institutional-grade finance integration, was also noted in the top networks in weekly commits. It is claimed that its development teams are working on improving transaction finality and adding future smart contract capabilities. This consistent performance can be an indication that the network is gearing towards being more programmable, which could have long-term competitive advantages.
