Conflux

Holding CFX pays no interest, but the protocol has interest-like features: a built-in 4% staking rate, a yield on storage collateral and passive PoS rewards through pools.

Riba is interest or any guaranteed increase on a loan. Sharlife, the first authoritative source that rates CFX, lists it as permissible. PoS rewards are variable, depend on total staking and carry slashing risk, which is a reward for securing the network rather than interest. But the Conflux website advertises built-in staking interest of an annualised 4%, the reward formula uses a DAO-set 'interestRate', storage collateral earns a protocol yield that CryptoUmmah calls interest-like, and pool delegators earn passively.

CFX is the working fuel of a public blockchain: it pays fees and storage and secures the network.

This criterion asks whether the asset has real value as property (mal). CFX is required to pay transaction fees and storage on Conflux and is staked to secure the network. Sharlife rates CFX permissible, and the general dispute among scholars about whether crypto is property is not a weakness of this coin, so the criterion is at the maximum.

CFX has no chance-based payout or meme mechanics.

Maysir is gambling: gaining or losing by chance rather than through productive exchange. CFX is a utility token for a blockchain network, with no lottery or game built into the token. Market speculation by traders is not a feature of the asset, so the criterion is at the maximum.

The protocol has no lending business or treasury income; fees go to miners or are burned.

This criterion asks how the issuer or network earns and whether any of that income is impermissible. Conflux fees are partly burned and partly paid to miners, and block rewards are newly minted CFX. CryptoUmmah finds no protocol treasury holding interest-bearing assets. No impermissible income is documented, so the criterion is at the maximum.

Code and economics are public and parameters change by on-chain vote, but most of the 5 billion genesis supply went to insiders and funds.

Gharar is excessive uncertainty or hidden information. Conflux's code is open, its economics and PoS rules are documented, and reward and burn parameters change only through on-chain DAO votes. The genesis supply was 5 billion pre-mined CFX, with 36% to the genesis team and 40% to an ecosystem fund, and in 2023 the team and foundation sold $10 million of CFX to DWF Labs on undisclosed unlock terms. This concentration lowers the score within pass.

CFX is used to run a general-purpose blockchain: fees, storage, staking and governance.

This criterion looks at what the asset is actually used for. CFX pays for transactions and storage on Conflux, which hosts general applications and has worked with public and corporate partners in China. No dominant impermissible use is documented, so the criterion is at the maximum.

Fully paid spot CFX is widely available and can be held in self-custody.

This criterion asks whether the asset can be owned in a permissible way. CFX trades spot with full payment and delivery on major exchanges and can be held in a Conflux wallet. Ownership does not depend on derivatives or leverage, so the criterion is at the maximum.

Conflux provides open blockchain infrastructure; no fraud or hack involving CFX is documented.

Maslahah weighs benefit against harm. Conflux offers low-cost public infrastructure and has served public and corporate projects. CryptoUmmah found no fraud allegations, rug-pull indicators or security breaches. No concrete harm is documented, so the criterion is at the maximum.
