Celestia

Holding TIA pays nothing; staking rewards are variable payments for validation and carry slashing risk.

Riba is interest or any guaranteed increase on a loan. TIA has no lending or interest function at protocol level. Staking rewards come from block rewards and fees, change with inflation and the share of TIA staked, and are paid for the work of validating; a validator that double-signs loses 2% of its stake, and delegators share that risk. This is payment for work with real risk, not a return on a loan, so the criterion is at the maximum. CryptoUmmah also finds no interest mechanism.

TIA is the native token of a working network and is needed to pay for its data availability service.

This criterion asks whether the asset has real value as property (mal). TIA is the native asset of a live network: rollups must pay TIA fees to publish data, and the token secures the chain and is used to vote. That is a clear, functioning utility. CryptoUmmah, the authoritative source, rates the token highly on this ground, so the general scholarly debate about whether crypto is property is reflected in confidence rather than in this score.

TIA is a utility token, not a game of chance; its large price swings are ordinary market risk.

Maysir is gambling: gaining or losing by chance rather than through productive exchange. TIA has no lottery, prediction or meme mechanics, and it is used to pay for a real service. The price has fallen about 98% from its 2024 high, which is a large market risk but not gambling in the asset itself. CryptoUmmah calls any maysir incidental. No coin-specific gambling feature is documented, so the criterion is at the maximum.

The network earns fees for publishing data; no interest, gambling or other impermissible income is involved.

This criterion asks how the protocol earns and whether any of it is impermissible. Celestia's income is fees paid by rollups for data availability, which go to validators and stakers, plus a 2% share of block rewards for the community pool. Celestia Labs is a software company funded by venture investors. No source shows interest-based or other impermissible revenue, so the criterion is at the maximum.

Rules and supply are public, but there is no supply cap, and early backers liquidated large staking rewards from locked tokens before an upgrade limited this.

Gharar is excessive uncertainty or hidden information. Celestia's allocation, vesting and inflation schedule are published, the code is open source and parameters can be read on-chain. Two concrete points lower the score within the pass band. TIA has no maximum supply: inflation has been cut from 8% to about 2.5% but continues towards a 1.5% floor, and total supply had grown from 1 billion to about 1.18 billion by October 2026.

TIA is used for data availability fees, rollup gas, staking and governance.

This criterion looks at what the asset is actually used for. TIA's uses are infrastructure: rollups pay it to publish data, some rollups use it as gas, and holders stake it and vote with it. Demand for data availability has been weaker than expected, as DL News reported in 2025, but low demand is not an impermissible use. No impermissible use is documented, so the criterion is at the maximum.

Fully paid spot TIA is available on major exchanges and can be held and staked from a self-custody wallet.

This criterion asks whether the asset can be owned in a permissible way. TIA has traded spot on Binance, KuCoin and Bybit since launch, and it is a native coin that can be held in a self-custody wallet and staked directly. Ownership does not depend on derivatives or leverage, so the criterion is at the maximum.

Celestia makes it cheaper to launch verifiable blockchains; no concrete harm is documented.

Maslahah weighs benefit against harm. Celestia's open-source data availability layer lowers the cost of building new blockchains and lets anyone verify that published data exists. No source shows the network being used mainly for fraud, sanctions evasion or other harm, and no major security incident was found. The criterion is therefore at the maximum.
