Which blockchain has better block speed, lower cost, higher security and better road for scaling up (network running smoothly with more and more dapps being created on it)?
NEAR protocol has horizontal sharding and infinite TPS with 2 second finality. It's account based and easy to use (no metamask required). It even has an L2 for appchains like polkadot and it can run Ethereum DApps in it's EVM contract Aurora, which accepts ETH to pay for gas natively and has the only 100% trustless bridge in crypto. You can already trade and yield farm on NEAR protocol on Ref Finance and more DeFi is being added every day.
