Blockspace

Celestia’s TIA token jumped roughly 11% after the network published a $1.5 million phased plan testing whether cheap data-availability blockspace can also generate durable protocol revenue. The proposal has not been put to a binding vote, and its outcome will determine whether Celestia’s low-cost model can scale without collapsing margins the way Ethereum’s blob fees did in 2025.

• TIA traded near $0.48 on September 23, 2026, up about 11% from the prior 24 hours, per CoinMarketCap.
• The updated Sustainable Blob Economy package, published September 22, 2026, groups six proposals under a $1.5 million spending ceiling.
• Celestia’s 30-day average DA cost of $0.0188 per MB undercuts Ethereum blobs at $0.0325 and EigenDA at $0.0363.

• $0.48 TIA price September 23, up 11% in 24 hours
• $1.5M total spending ceiling across six governance proposals
• 55 networks now posting data to Celestia’s DA layer

Celestia’s TIA traded near $0.48 on Wednesday, September 23, 2026, up about 11% from the previous 24 hours, according to CoinMarketCap data. The rally followed the network’s release a day earlier of an updated Sustainable Blob Economy governance package. The document asks a question bigger than price: can Celestia keep blockspace cheap enough to attract rollups while turning that usage into steady protocol income.

Celestia Sets $1.5 Million Ceiling For Three-Phase Blob Economy Plan

The forum package groups six proposals under a single $1.5 million expenditure ceiling, with $225,000 earmarked for a feasibility-and-design phase. That figure rises to $825,000 for an implementation-and-integration phase, followed by a $450,000 independent review and pilot-preparation stage. Each tranche functions as a spending cap rather than an automatic transfer, and every phase requires its own separate community approval before funds move.

The package limits what forum backing alone can achieve. Support in the forum sets direction, but it does not execute a community-pool transfer, approve unspecified software, or count as adoption of a formal Celestia Improvement Proposal.

Celestia’s DA Costs Undercut Ethereum by 42% and EigenDA by 48%

Usage data underpins the case for charging more without pricing rollups out. The Celestia Data dashboard, built on Numia’s infrastructure, shows 55 networks now posting to Celestia, with more than 4,100 GB submitted to date. Historical revenue sits near 437,000 TIA, including roughly 6,500 TIA earned over the past month alone.
