Solana (SOL) Raises Mainnet Block Limit to 100M CU

Solana News

As of July 29, Solana (SOL) has moved its mainnet block capacity upgrade into production, raising the compute ceiling from 60 million to 100 million compute units per block. The change, formalized through SIMD-0286 and backed by validator signaling above 70% of stake, expands block space by 66% while keeping block times near 400 milliseconds. Because the per-account write cap remains at 12 million compute units, the added capacity is intended to widen parallel execution rather than let a single hot account dominate a block. The modification does not require applications or exchanges to rebuild indexing logic, reducing operational risk for teams that cannot pause services during protocol transitions. That compatibility profile matters because previous capacity changes sometimes forced developers to adjust transaction packing or monitoring assumptions. For the broader altcoin sector, the update is a direct response to congestion risks during high-frequency trading episodes, especially in automated market maker venues and consumer applications that require low-latency settlement. The Solana network rollout arrives while SOL changes hands in a tight $72 to $74 band, with market participants treating the $73.75 area as a large accumulated position zone. Macro pressure from firmer U.S. Treasury yields and a stronger dollar has capped risk appetite, but the upgrade itself gives the chain more room to absorb bursts of decentralized exchange activity without fee spikes.

Solana's price structure is also showing a familiar technical warning. The token has formed two stalled advances around the $74 region, with chart peaks near July 15 and July 22 and an intervening low around July 17. That shape resembles a double top, a reversal pattern often linked to late-stage exhaustion rather than a full bear market unless confirmation follows. The critical line sits near $73, while the pattern base is close to $72. A daily close below that base would confirm the formation and activate a measured projection of roughly 7%, pointing toward the $67 area. If selling accelerates, traders have flagged $60 as a deeper liquidity zone. The current setup is developing on weaker purchase volume, meaning fewer buyers are defending each rebound. Volume divergence suggests the market is not yet pricing a decisive breakdown, but it also shows rallies are meeting thinner demand. A confirmed neckline break would convert the $73 area from support into resistance, making recovery attempts harder to sustain. That condition echoes the spring version of the pattern, which formed between mid-March and May 11 and preceded a 21% decline. However, the present structure is less symmetrical, and the risk remains active only while SOL trades below the $79 zone. A daily close above $81, and preferably above $84, would break the sequence and reopen the prior range.

On-chain signals add a second layer to the debate. Exchange net position change, which tracks tokens moving into and out of trading venues, is far lighter than during the spring pattern. In the earlier episode, the metric was deeply negative near 8 million SOL in mid-March before easing to about 5.4 million SOL by May 11. The current formation shows only about 0.2 million SOL in mid-July rising to roughly 0.9 million SOL by July 22. Those smaller readings point to weaker distribution pressure and may explain why the chart pattern looks less balanced. The more concerning signal comes from long-term supply. The one-to-two-year HODL wave, a measure of coins held by conviction investors, stayed near 15.9% during the spring top. This time it slipped from about 15.7% in mid-July to 15.17% by July 28. That decline suggests patient holders are trimming exposure while the pattern develops, removing a support that was present earlier. For an Altcoin still trying to stabilize after a weak week, the combination is mixed: exchange selling is not aggressive, but the investor base is less passive. A move toward an all-time high would require these cohorts to stop reducing. If the HODL band continues lower, chart support could fail even without a large spike in exchange inflows.

COINOTAG's proprietary 42-indicator composite S/R scoring engine rates Solana's $74.50 resistance at 76/100, driven by SMA 50 and Fibo 0.382, while the $73.21 support scores 61/100 from Ichimoku Senkou A and Stoch OS. With spot at $73.25, funding at 0.0037%, $1.36B open interest and a 3.02 long/short ratio, positioning is crowded long but not euphoric. Fear and Greed at 29 signals fear. A hold above $73.21 and reclaim of $74.50 could expose $78.10; a daily loss below $70.16 would weaken the structure and open $64.49. That invalidation aligns with the bearish MACD signal and downtrend label in our trend model, raising the importance of the $70.16 floor.
