The recent on-chain estimates indicate that developer inputs in the major blockchain ecosystems have plunged. Ethereum continued to lead the top development events, but the whole industry saw a decline, with other leading platforms such as Polygon, BNB Chain, and Solana.

Ethereum had 87.4K development activity events, making it the most active network. However, it also recorded a 31.07% reduction in overall events and a 15.5% reduction in unique contributors, which amounted to 1.4K. Ethereum had a considerable lead over other ecosystems, although this had declined.

The second-most active was Polygon, with 40.5K events but this was a 29.59% decline. The number of its contributors dropped by 10.59% to 591. In the meantime, the BNB chain published 40.2K events, a decrease of 28.3%, and its contributors decreased by 13.1% to 756. The three networks declined with a decrease in the development momentum of the major chains.

Two leading Ethereum Layer-2s, Arbitrum and Optimism, recorded a decrease in developer activity and the number of contributors. Arbitrum experienced a decline of 33.28% to 33.9K events, where the contributors were reduced by 15.29% to 471. Optimism came next with a 32.% decrease in events (32K) and 8.87 %  decrease in contributors (421).

Cosmos, Avalanche, and Solana demonstrated similar negative dynamics. Cosmos recorded 27.7K development events, and the contributors dropped by 11.94%. Avalanche had 27.3K occurrences and a 13.29% decrease in contributors. Solana, commonly described as a high-throughput blockchain, experienced a 34.65% decline in development activity and an 8.5% drop in contributors.

Harmony and Polkadot, ranked ninth and tenth, had the highest drops in developer activity. Harmony’s events decreased by 40.73 to 20.7K, and Polkadot’s by 36.6% to 18.4 K. Their contributor numbers dropped 13.48 percent and 13.79 percent, respectively.

All ten ecosystems saw more than a ten per cent decrease in the number of events related to development activity. These decreases are between 22.55% in Cosmos up to more than 40% in Harmony. The figures of contributors also reduced, yet slower, which points to the idea that the number of events dropped through the roof, but many developers did not quit.
