Layer 33, a group of 25 independent Solana validators, has launched a coordinated effort to maintain the network's decentralization by managing a single staking pool aimed at controlling 33% of the total staked SOL. This initiative responds to centralization risks, as the top 20 validators currently control over 33% of the staked supply, surpassing Solana's Nakamoto coefficient threshold of 20%. The move comes amid significant institutional interest, highlighted by a $621 million net inflow into Solana ETFs and Franklin Templeton's ETF application, which have exacerbated centralization concerns. The coalition's strategy seeks to mitigate stake concentration and support smaller validators, with recent updates like Alpenglow's removal of voting fees potentially benefiting smaller operators.
