Major upgrade
London upgrade, introducing EIP-1599 proposal, increasing ETH burning
Paris upgrade, Ethereum consensus mechanism changes from POW to POS
Shanghai Upgrade, Scalability, Security and Sustainability
Cancun upgrade, introducing EIP-4844 proposal to reduce the cost/gas of layer 2 rollup solutions
Other upgrades that may be included in the Cancun Upgrade include:
EIP-6780 (preparing for future use of Verkle trees);
EIP-6475 (provides better readability and compact serialization);
EIP-1153 (Introducing transient storage opcodes).
Cancun before and after upgrade
Before upgrade: L2 information is stored in Calldata of L1 information
After the upgrade: L1 will be stored in a new location called "Blob", reducing the cost/gas of layer 2 rollup solutions
Pros:
Good for L2 protocol and the ecosystem in L2 protocol, OP ecosystem and ZK ecosystem continue to prosper
Optimism (OP) \ Arbitrum (ARB): currently occupies the vast majority of the market
On-chain futures DEX: GMX, GNS
Decentralized Options DEX: Dopex
Zksync: Leading ZK Series Layer2 Protocol
Starknet: Good for processing large orders
Dydx(DYDX): Leading Derivatives DEX
Loopring(LRC): Early DEX
Immutable(IMX): Gaming NFT Assets
Layerzero: Cross-chain Track
Summary: Ethereum is the world's largest universal ledger. Since the transition from POW to POS, it has brought some selling pressure in the short term. However, every important upgrade is often a hot topic in the industry. For example, the Shanghai upgrade has brought the LSD track to the forefront. The Cancun upgrade is no less than the Shanghai upgrade, reducing the transmission cost between L1 and L2, achieving low gas fees and high TPS
