Tokens associated with Bitcoin layer 2 solutions have outperformed bitcoin (BTC) since the Bitcoin blockchain’s highly-anticipated mining reward halving took effect early Saturday. STX, the native token of leading Bitcoin layer 2 network Stacks, has risen nearly 20% to $2.87 since quadrennial halving reduced the per block coin emission to 3.125 BTC from 6.25 BTC, according to data source CoinGecko. Bitcoin, meanwhile, has gained just over 4.7% to $66,300. STX is one of the best-performing top 25 cryptocurrencies of the past 24 hours, per Velo Data. Other layer 2 coins, like Elastos’ ELA token and SatoshiVM’s SAVM, have risen 11% and 5%, respectively, since halving. Bitcoin layer 2 solutions are projects that address scalability and transaction speed limitations on the Bitcoin blockchain. They are built on top of the Bitcoin blockchain and bring scalability by processing transactions off the main chain.
