Ethereum: Vitalik Maps Lean Upgrades Over Three Years

Ethereum researchers advanced the protocol roadmap in Berlin, confirming Lean Ethereum will replace verification, consensus and state architecture over three to four years in the same scale as the Merge.

Vitalik Buterin highlighted recursive STARKs as a core component, quantum-safe replacements across the stack, decoupled finality, multidimensional gas and new state types that keep dynamic state near 2 TB while scaling restrictive state to 100 TB for ERC20s and NFTs.

Price action on the 4h chart shows ETH trading at $1782.78 inside the Bollinger Bands with upper resistance at $1811.6 and lower support at $1687.73; the 50-EMA at $1690.83 and 200-EMA at $1747.03 remain key levels while RSI at 67.21 stays neutral and the MACD death cross at 36.42 signals near-term momentum loss, pointing to a probable retracement toward the 50-EMA before any continuation higher. ETH price prediction models now incorporate these protocol simplifications as primary drivers of long-term infrastructure resilience rather than short-term hype cycles.
