If you use Bitcoin or Ethereum, you've probably encountered two problems: high transfer fees and long transaction waiting times. This happens due to network congestion – too many users performing operations simultaneously.

Layer 2 (L2) or second-layer solutions were created specifically to solve these problems. These are additional technologies that work on top of the main blockchain and help it handle the load.

Main advantages of Layer 2

Low transfer fees
Instant transactions
Same level of security as the main network
Support for all major cryptocurrencies
Ability to work with popular applications

Technical features of Layer 2

How Rollups work

Multiple transactions are bundled into one package
The package is sent to the main network as one transaction
This reduces the cost of each individual operation

Optimistic Rollups

Assume all transactions are valid
Have a dispute period (usually 7 days)
Anyone can prove fraud
Used in Arbitrum and Optimism

ZK-Rollups

Use mathematical proofs
Each transaction is verified instantly
No dispute period
More technically complex
Applied in Polygon

Technical indicators

Transaction speed

Bitcoin: 5-7 TPS (transactions per second)
Ethereum: about 15 TPS
Layer 2: thousands of TPS

Current volumes

Lightning Network: over 3900 BTC in channels
Polygon: millions of transactions daily
Arbitrum and Optimism: growing adoption

Smart contracts in Layer 2

Core functions

User funds storage
Transaction verification
Dispute resolution
Interaction with the main network

Technical features

EVM compatibility
Standard token support
Code update capability
Emergency stop mechanisms

Conclusion

Layer 2 solutions make cryptocurrency usage simpler and more accessible. They remove the main obstacles – high fees and slow transfers, while maintaining all the advantages of blockchain. Remember, Polygon Matic can be best exchanged for fiat in comfortable offices in Tbilisi and Batumi at AllTrust.Me company.
