When exploring the blockchain ecosystem, it helps to understand the distinct features of different networks. BTC stands as the most secure blockchain available thanks to its PoW foundation. It functions beautifully as hard money and a trusted digital SoV, though it completely lacks native smart contracts. Meanwhile, ETH shifts the priority toward being performance focused. It fully supports native smart contracts but operates without PoW security. ETC bridges these two approaches by maintaining robust PoW security alongside its role as a reliable digital SoV. Because it also incorporates L1 smart contracts, ETC effectively operates as programmable digital gold.
