L0, L1, L2 Blockchains
L0 blockchains enable developers to create custom blockchains. L1 chains validate & execute transactions without the need for any external network. L2 blockchains are "sidechains" built on L1 chains.
Layer-0 Blockchains
Layer-0 blockchains enable developers to create custom blockchains.
Example: Polkadot enables the creation of sovereign blockchains with their own tokens.
These parachains plug into a single base platform called the Relay Chain which is responsible for shared security, consensus & cross-chain interoperability.
Other examples of L0 are Cosmos, and Horizen.
L0 blockchains are different from Blockchain Frameworks like Multichain and Hyperledger Fabric.
Frameworks are open-source software that enable developers to create custom blockchains.
Remember: Layer-0 blockchains are networks while Frameworks are software programs.
Layer-1 Blockchains
Layer-1 blockchains validate & execute transactions without the need for any external network.
Example: Bitcoin, and Ethereum Mainnet.
Layer-2 Blockchains
Layer-2 blockchains are "sidechains" built on top of Layer-1 blockchains.
The underlying Layer-1 (e.g. Ethereum Mainnet) provides the decentralization & security, while the Layer-2 (e.g. Polygon PoS) provides the scalability.
Can I extend your definition as follows? L0 blockchains are the custom blackhain networks built using a frameworks like Hyperledger. L1 networks are private networks built using geth and L2 network is a network of nodes connected to an L1 network for added functionality like storage,logic, scale etc.. and an L2 network cannot exist
