What is layer-1 and layer-2 in blockchain?

While the layer-1 blockchain is more like a parent chain and has the role of offering security and maintaining the ledger, a layer-2 chain is more like a scaling solution! As for examples of layer-1 blockchain protocols, you can look at Bitcoin and Ethereum. Layer-2 solutions include the lightning network for Bitcoin and networks like Arbitrum and Optimism for Ethereum. Also, layer-2 chains are built on top of the parent layer-1 blockchain and offer higher transaction speeds.

What is layer-0 and layer-1 blockchain?

Layer-1 chains are all about the foundational, security-heavy blockchain networks. You can think of them as the base layer for someone interested in building a blockchain-led infrastructure. Layer-0 chains, on the other hand, are more like interoperability players, which can pave the way for other layer-1 chains. One such example of a layer-0 chain is Polkadot, with a dedicated Parachain network.

Is Solana layer-1 or 2?

Solana is a reputed layer-1 blockchain. Unlike Ethereum, which suffers from scalability issues, Solana boasts a far better transaction speed limit followed by a tested proof-of-stake consensus mechanism. Solana is one of the few blockchain networks to address concerns related to the blockchain trilemma.

Is Cardano a layer-2 blockchain?

Cardano is a layer-1 blockchain boasting the proof-of-stake consensus mechanism for validating transactions. Cardano network also supports a wide range of decentralized applications. Plus, it is a highly peer-reviewed ecosystem with a massive user base.

Is Polkadot layer-1 or 2?

Polkadot is primarily a layer-0 platform, which takes care of the blockchain interoperability concern. However, its network of parachains also qualifies Polkadot as one of the more popular blockchain networks. Each parachain can work as a standalone layer-1 blockchain.

Is MATIC layer-1 or 2?

The Matic Network or Polygon is a layer-2 blockchain or, rather, a solution. It is built on top of Ethereum, a layer-1 blockchain, borrowing the parent chain’s security posture. In return, Polygon ensures improved transaction speed.
