Ethereum Merge: Transitioning to Proof-of-Stake
Ethereum's evolution has been strategically planned since its inception in 2014, progressing through four key phases:
- Frontier (2015) – Initial launch with basic functionalities.
- Homestead (2016) – Stability improvements.
- Metropolis (2017–2019) – Enhanced privacy and smart contract capabilities.
- Serenity (Ethereum 2.0) – Shift from Proof-of-Work (PoW) to Proof-of-Stake (PoS).
The Merge marked Ethereum’s transition to Serenity, replacing energy-intensive mining with staking. This upgrade significantly reduced energy consumption by 99.95% while maintaining security through validators.

EVM Explained: The Engine Behind Ethereum Smart Contracts
The Ethereum Virtual Machine (EVM) executes smart contracts by translating high-level code (e.g., Solidity) into bytecode readable by the blockchain. Think of it as:
| Component | Role |
|---------------------|------------------------------------------|
| Java Virtual Machine | Runs Java bytecode on any OS. |
| EVM | Executes smart contracts across nodes. |
eWASM: The Future Upgrade
eWASM (Ethereum-flavored WebAssembly) aims to replace EVM, enabling faster execution and broader developer accessibility by supporting multiple programming languages.
ERC-4337 & Account Abstraction: Simplifying Ethereum UX
Introduced in 2023, ERC-4337 revolutionizes user interaction by:
- Enabling smart contract wallets (e.g., social recovery, gas fee sponsorships).
- Removing seed phrases via signature abstraction.
- Batching transactions for efficiency.

2024 Blockchain Innovations: The Rise of Inscriptions
Inscriptions (similar to NFTs) embed data directly onto blockchain units like Bitcoin’s satoshis. Key developments:
- BRC-20: Token standard on Bitcoin (e.g., ORDI).
- Ethscriptions: Ethereum’s counterpart using calldata.
Why it matters: Low-cost alternative to traditional NFTs with on-chain provenance.
Starknet: Scaling Ethereum with ZK-Rollups
Starknet, a ZK-Rollup Layer 2 solution, addresses Ethereum’s scalability by:
- Bundling transactions off-chain.
- Using STARK proofs for validation.
- Reducing fees by ~90% vs. mainnet.
| Feature | Benefit |
|--------------------|----------------------------------------|
| Decentralized | No single point of failure. |
| EVM-Compatible | Supports existing Ethereum dApps. |
FAQ
Q: Is Ethereum 2.0 fully live?
A: Yes! The Merge completed the PoS transition, but further upgrades (e.g., sharding) are ongoing.
Q: How do I store ETH securely?
A: Use non-custodial wallets like MetaMask or Ledger.
Q: Are inscriptions the same as NFTs?
A: Similar, but inscriptions store data directly on-chain, unlike most NFT metadata.
Q: What’s the advantage of account abstraction?
A: It eliminates seed phrases and allows gas-free transactions via paymasters.
Q: Can Starknet work with other blockchains?
A: Currently optimized for Ethereum, but its tech may expand cross-chain.
