Jihoon Song, known as @jih2nn, electrified the EthCC crowd in 2026 with a deep dive into FOCIL's journey, revealing its roots in Ethereum's scaling challenges over the past year. He traced FOCIL's emergence from early 2025 experiments aimed at optimizing layer-2 finality, addressing bottlenecks that plagued high-throughput dApps during the crypto market surge last summer. Song highlighted seamless integrations with Frame transactions, demonstrating how FOCIL enhances cross-chain efficiency without compromising security, a move that could redefine DeFi protocols amid rising adoption.
Bridging Past Innovations to Future Blob Support
Song didn't stop at history; he projected FOCIL's evolution toward blob support, a critical upgrade echoing Ethereum's Dencun hard fork advancements from mid-2025. This forward-looking vision positions FOCIL as a cornerstone for blob data handling, potentially slashing costs for rollups and boosting scalability. Attendees buzzed about the implications for institutional Ethereum adoption, especially as regulatory clarity in the EU stabilized crypto frameworks over the last six months.
ETH Price Action: Confluence Signals Bullish Continuation
From my perch as a senior macro-crypto trader, ETH's 4-hour chart screams controlled bullish momentum, with the price at $2236.12 hugging the upper reaches of its volatility bands while the MACD locks in a golden cross at 41.39, confirming trend strength that echoes the rallies we traded through late 2025. Confluence builds as this neutral RSI of 69.1 avoids overbought territory, suggesting room for upside before exhaustion hits the upper Bollinger resistance at $2276.69—yet if sellers emerge, expect a tactical pullback to the EMA50 support at $2113.16, reinforced by the EMA200 floor at $2072.2, setting up for another leg higher in this established uptrend. Institutional flows will watch that lower band support at $2003.46 closely, as any breach could flip the script, but for now, the structure favors longs targeting fresh highs.
