Trading Notes | Public Blockchains and the Blockchain Trilemma
① Different public blockchains choose different consensus mechanisms and design trade-offs, so block times, confirmation speeds, and fees vary considerably.
② Layer 2 networks move transaction execution off the mainnet, then rely on Layer 1 consensus to settle transactions—one approach to easing the blockchain trilemma.
③ When you see a public blockchain advertised as “ultra-fast and practically free,” ask what trade-offs it makes.
