Layer one (L1) and layer two (L2) blockchains offer different approaches to scaling distributed ledger networks. While developers of L1 blockchains focus on improving the base protocol, L2 programmers have moved transactions off-chain to enable faster and cheaper transactions. What Are Layer One Blockchains? Layer one or L1 refers to a base blockchain protocol like Bitcoin or Ethereum. These networks operate on a decentralized ledger secured by proof-of-work (PoW) mining or proof-of-stake (PoS) staking . L1 chains such as Bitcoin and Ethereum offer unparalleled security. However, during peak times, both of these chains grapple with sluggish transaction speeds and steep fees. Developers from several L1 networks are working to improve layer one scaling through methods like increasing block size, sharding , and introducing proof-of-stake consensus. However, substantial layer one upgrades require coordination among node operators and can take years to implement. Some blockchains inte...
