What is Core?

What Makes Core Unique?

Core is a Layer 1 blockchain that introduces a novel consensus mechanism called Satoshi Plus, which combines delegated Proof of Work (dPoW) from Bitcoin miners with delegated Proof of Stake (dPoS) from CORE token holders. This hybrid design allows Bitcoin miners to contribute hash power to Core's security without redirecting it away from Bitcoin itself, effectively extending Bitcoin's economic utility into a programmable smart contract environment.

Core Features

  • Satoshi Plus Consensus: A dual-layer consensus mechanism that merges Bitcoin miner delegation with CORE token staking, producing a security model that draws on both the world's largest proof-of-work network and a native staking economy simultaneously.
  • Bitcoin-Aligned Staking: Bitcoin holders can participate in Core's staking ecosystem through non-custodial mechanisms, earning CORE rewards without moving their BTC off the Bitcoin network, preserving custody while generating yield.
  • EVM Compatibility: Core is fully compatible with the Ethereum Virtual Machine, enabling developers to deploy Solidity-based smart contracts and decentralized applications with minimal friction, drawing from the existing Ethereum developer ecosystem.
  • Coretime and Dual Staking: The protocol supports a layered staking model where combining BTC and CORE staking positions unlocks higher reward tiers, incentivizing long-term participation and deeper protocol alignment rather than short-term liquidity provision.

What Is Core Used For?

Core functions as a general-purpose smart contract platform with a particular emphasis on Bitcoin-native DeFi, positioning itself as infrastructure for users who want programmable finance without abandoning Bitcoin's security assumptions. The ecosystem hosts projects such as Nawa Finance, which offers Shariah-conscious on-chain yield strategies built on Core's staking primitives, as well as Solv Protocol integrations that bring Bitcoin liquidity into structured yield products. Core's adoption narrative centers on becoming the leading platform for Bitcoin DeFi, attracting both institutional Bitcoin holders seeking productive use of idle BTC and developers building decentralized applications that inherit Bitcoin's trust model.

CORE and Islamic finance principles

Islamic Finance Principles Assessment

Riba - Does Core Include Any Interest-Based Elements?

Core's protocol design does not incorporate interest-bearing instruments at the base layer; its revenue and reward mechanisms are structured around network participation and fee generation rather than fixed returns on loaned capital. The staking rewards distributed to CORE and BTC delegators are variable and performance-linked, which places them outside the classical definition of riba. For Muslim investors, the protocol's own architecture presents no inherent interest-based element, though individual DeFi applications built on top of Core must be evaluated separately on their own terms.

Assessment: Minor Riba Score: 80.7/100

Our methodology examines 10 specific criteria to evaluate how well Core avoids interest-based mechanisms.

Core's revenue model at the protocol level consists of transaction fees paid by users for computation and settlement, along with block rewards distributed to validators and stakers from a pre-defined token emission schedule. Neither of these income streams constitutes riba, as they represent compensation for a productive service rendered — network security and transaction processing — rather than a return on a loan of money. The protocol treasury, funded through a portion of block rewards and fees, holds CORE tokens rather than interest-bearing financial instruments. There is no evidence of the protocol deploying treasury assets into conventional bond markets or any fixed-income vehicle that would introduce riba into its balance sheet.

The staking rewards within Core's Satoshi Plus system are variable by design, fluctuating with network activity, total staked supply, and the proportion of hash power delegated by Bitcoin miners. This variability is a structurally important distinction from riba, which requires a predetermined, contractually fixed increment on a principal sum. Rewards are sourced from two permissible origins: newly minted CORE tokens distributed according to the protocol's emission schedule, and a share of transaction fees generated by genuine economic activity on the network. The Dual Staking mechanism, which adjusts reward rates based on the ratio of BTC to CORE staked, further reinforces the performance-based rather than fixed-return character of the system.


Gharar - How Much Uncertainty Does Core Involve?

Core involves a moderate level of uncertainty typical of early-stage Layer 1 blockchain protocols, arising primarily from the nascent state of its ecosystem, the evolving adoption of its Bitcoin DeFi thesis, and the inherent price volatility of its native token. These uncertainties are meaningfully reduced by the protocol's open-source codebase, its publicly documented consensus mechanism, and the transparency of on-chain data. On balance, the gharar present in Core is of the kind that accompanies any legitimate commercial venture operating in an emerging market, rather than the excessive, concealed uncertainty that Islamic jurisprudence identifies as impermissible.

Assessment: Minor Gharar (Mostly Clear) Score: 78.6/100

Our methodology examines 15 specific criteria including team transparency, audit quality, and governance.

Core's development is led by the Core DAO, a decentralized autonomous organization whose contributors have operated with varying degrees of public visibility, a characteristic common to DAO-governed protocols. The codebase is open-source and publicly accessible, allowing independent developers and security researchers to inspect the consensus logic, tokenomics contracts, and governance mechanisms without restriction. On-chain data provides real-time transparency into validator activity, staking participation, and treasury flows. While the founding team's individual identities are not as prominently disclosed as those of traditional corporate entities, the open-source and on-chain nature of the protocol substantially mitigates the informational asymmetry that constitutes problematic gharar.

Core's technical documentation covers the Satoshi Plus consensus mechanism in considerable detail, including the mathematical weighting of hash power delegation and staking participation in validator election. The protocol has undergone third-party security audits, as is standard practice for EVM-compatible chains seeking developer and user trust, though Muslim investors should verify the currency and scope of any audit reports independently. Risk disclosures in the ecosystem are primarily communicated through community documentation and governance forums rather than formal prospectus-style filings, which is consistent with decentralized protocol norms. The availability of this information in the public domain reduces gharar to a level commensurate with other transparent open-source blockchain protocols.


Maysir - Does Core Involve Gambling or Speculation?

Core is not designed as a gambling instrument; its architecture is oriented toward providing security infrastructure, enabling smart contract execution, and facilitating Bitcoin-native financial applications with genuine productive utility. The presence of speculative trading in CORE tokens on secondary markets is a behavior of market participants, not a function of the protocol's design, and does not render the protocol itself analogous to maysir. The distinction between a productive network asset that fluctuates in price and a zero-sum wagering instrument is clear and well-established in contemporary Islamic finance discourse.

Assessment: Minor Maysir (Incidental) Score: 78.9/100

Our methodology examines 11 specific criteria to determine if Core is primarily a gambling instrument or a genuine economic tool.

Core's real-world utility is grounded in several concrete functions: it provides a security layer for smart contract execution, compensates Bitcoin miners for contributing hash power to a productive network, and enables Bitcoin holders to deploy their assets in yield-generating strategies without relinquishing custody. These are services with identifiable economic value — computation, settlement finality, and capital efficiency — that exist independently of any speculative price movement. The Dual Staking mechanism creates genuine incentive alignment between long-term holders and the network's health, rewarding sustained participation rather than short-term trading. This productive function is the antithesis of maysir, which involves a pure transfer of wealth based on chance with no underlying value creation.

The presence of speculative trading in CORE tokens on centralized and decentralized exchanges is an observable market reality, and it would be intellectually dishonest to ignore it. However, speculation by third-party traders on secondary markets does not transform the underlying protocol into a gambling instrument, just as speculative trading in commodity futures does not make wheat or oil impermissible. Core's growing ecosystem, including Nawa Finance's Shariah-conscious yield products and Solv Protocol integrations, provides evidence of genuine adoption beyond price speculation. The utility-to-speculation balance is still maturing given the protocol's relative youth, but the trajectory of real use cases anchors the asset in the domain of productive economic activity rather than chance-based gain.

CORE staking and rewards

Is Staking Core Halal?

Staking Core (CORE) tokens appears to be permissible under Islamic finance principles, provided the rewards are treated as variable profit-sharing returns rather than guaranteed fixed income. The non-custodial, delegation-based structure aligns well with recognized Islamic contract forms, and the absence of guaranteed yields removes the primary riba concern. As with any significant financial commitment, holders of substantial positions are advised to consult a qualified Shariah scholar for personalised guidance.

Staking Score: 78/100

Islamic Contract Classification: Core's staking mechanism is best classified through a combination of Wakalah and Mudarabah frameworks, both of which are well-regarded in Islamic commercial jurisprudence. The delegator acts as a principal appointing a validator as agent (wakil) to perform network security tasks on their behalf, which is the essence of Wakalah. Simultaneously, the relationship carries Mudarabah characteristics: the staker contributes capital in the form of timelocked BTC or CORE tokens, while the validator contributes operational effort and expertise, with rewards distributed according to performance rather than at a fixed, pre-agreed rate. Crucially, returns are variable and contingent on actual block production and network participation, meaning there is no riba-bearing guarantee of profit. This risk-and-reward sharing structure is precisely what Islamic finance endorses as a legitimate alternative to interest-bearing instruments.

How It Works: Core operates on the Satoshi Plus consensus mechanism, an innovative hybrid that combines Delegated Proof of Work, Self-Custodial Bitcoin Staking, and Delegated Proof of Stake. Delegators assign their BTC or CORE tokens to validators who compete for election to a daily rotating set of active block producers; the delegator never relinquishes custody of their assets, as Bitcoin is secured through cryptographic absolute time-locks rather than transferred to a third party. This fully non-custodial design is a meaningful Shariah-positive feature, as it avoids the ambiguity of pooled custody arrangements. Lock-up periods are tied to timelock expiration or daily election cycles rather than arbitrary freezes, preserving a reasonable degree of liquidity. Slashing risk falls primarily on validators, who must post a refundable bond and face jailing or penalty for misbehavior, while delegators bear only the indirect risk of choosing a poorly performing validator, a level of exposure consistent with legitimate commercial risk-taking rather than speculative uncertainty.

Final verdict: is Core halal?

Is Core Shariah Compliant?

Overall Shariah Compliance: 79.5/100

Halal (Light Purification)

Core lands at light purification because its foundational design is substantively sound from a Shariah perspective: genuine utility underpins the token, staking rewards are variable and risk-contingent rather than riba-bearing, and the non-custodial architecture respects the principle of property rights. The residual concern is not with Core's own design but with the broader DeFi ecosystem it hosts; as an EVM-compatible platform, it enables third-party applications that may involve gharar-heavy derivatives or maysir-adjacent speculation, and a proportionate purification of rewards is prudent to account for any incidental exposure to such activity within the network's transaction flow.

In our screening, Core scores 79.5/100 overall — Riba 80.7/100, Gharar 78.6/100, Maysir 78.9/100.

Recommended Purification: 1.0-1.5% of profits

  • Calculate net profits from all Core holdings and staking rewards
  • Donate 1.0-1.5% to charity (these are not zakat recipients — use separate charitable channels)
  • Example: $1,000 profit -> $10-15 to charity -> $985-990 remains halal
  • Suitable causes: medical relief, orphan support, disaster relief, clean water projects

Legitimacy Summary: Core presents a credible project with a publicly identifiable and credentialed team, no reported fraud indicators, and genuine utility in AI-blockchain infrastructure, supporting a strong legitimacy profile.


2. Project Operations Screening (9 Criteria)

CriterionScoreDetailed Analysis
Core Protocol Business85/100The base protocol operates as an AI-blockchain infrastructure layer with no involvement in prohibited sectors such as gambling, interest-based finance, or alcohol at the protocol level itself.
Transaction Fees80/100Transaction fees are used for network operations and include a deflationary burn mechanism, with no evidence of riba-like extraction or exploitative fee structures at the protocol level.
Treasury Assets72/100No specific treasury asset composition is disclosed in the available research, and the absence of clear disclosure leaves open the question of whether interest-bearing instruments are held, though no such holdings are reported.
Revenue Model78/100Revenue appears to derive from transaction fees and block rewards tied to network activity rather than interest-based mechanisms, though detailed protocol-level financial disclosures are limited in the available research.
Transparency82/100The codebase is substantially open-source on GitHub, on-chain operations are auditable, and governance and tokenomics are publicly documented, though some enterprise AI model components remain proprietary.
Governance80/100On-chain governance through Core DAO allows token holders to vote on network parameters, treasury decisions, and validator regulations, representing a meaningful decentralized governance structure.
Launch Fairness75/100Token distribution includes public vesting schedules and no reported excessive insider allocation, though the research does not provide granular detail on the initial launch mechanics to fully confirm fairness.
Token Distribution74/100Vesting schedules are described as public and team allocation is not flagged as excessive, but the research lacks sufficient detail on the breadth of initial distribution to assign a high score with confidence.
Speculation/Utility Ratio78/100The token serves clear operational functions including gas fees, staking, and governance, and the project has measurable TVL and real adoption, indicating utility dominates over pure speculation in its design.

Operations Summary: The base protocol operates in a permissible sector with open-source transparency and decentralized governance, though detailed treasury and financial disclosures remain limited in available research.


3. Financial Health Screening (4 Criteria)

CriterionScoreDetailed Analysis
Protocol Revenue80/100Protocol revenue is derived from transaction fees and block rewards linked to network activity, with no evidence of interest-based or riba-generating revenue streams at the base protocol level.
Financial Status68/100While the project shows signs of operational stability and community growth, specific financial disclosures such as treasury size, burn rate, and runway are not detailed in the available research, limiting confidence.
Interest Assessment82/100The base protocol does not natively offer lending or borrowing with interest, and any such features exist only in third-party dApps built on the network, which do not implicate the protocol's own design.
Audit Quality70/100Smart contract audits by CertiK are mentioned, but the research does not provide specific audit dates, scope, or public findings reports, leaving the depth and completeness of the audit trail partially unverified.

Financial Summary: Protocol revenue derives from transaction fees and block rewards with no evidence of interest-based income, but the absence of granular financial disclosures moderates confidence in the overall financial assessment.


4. Token Economics Screening (5 Criteria)

CriterionScoreDetailed Analysis
Token Purpose88/100CORE functions as a genuine utility token required for transaction fees, smart contract execution, staking in the Satoshi Plus consensus, and on-chain governance, with no meme or purely speculative character.
Governance Rights82/100CORE holders exercise on-chain governance rights through Core DAO, including voting on network parameters, block rewards, and validator regulations, representing clear and functional governance participation.
Rewards Distribution85/100Staking rewards are variable and derived from block rewards and transaction fees based on validator performance and network participation, with no fixed or guaranteed return structure resembling interest.
Speculation Controls65/100Anti-speculation controls are indirect, relying on staking incentives for long-term holding and a fixed supply with fee burns, but explicit mechanisms such as whale caps or strong lock-up requirements are not documented.
Asset Backing84/100The token is backed by genuine network utility encompassing fees, staking, governance, and Bitcoin-enhanced DeFi, with no reliance on debt instruments, interest, or prohibited asset classes.

Tokenomics Summary: CORE is a genuine utility token with clear operational functions, on-chain governance rights, variable reward structures, and halal-aligned asset backing, though explicit anti-speculation mechanisms could be stronger.


5. Staking Mechanism Screening (5 Criteria)

CriterionScoreDetailed Analysis
Mechanism Type82/100Staking is fully non-custodial with Bitcoin holders retaining control via cryptographic time-locks, and delegation to validators is flexible with daily election rounds, though timelocks introduce some degree of illiquidity.
Islamic Contract Classification78/100The staking structure most closely resembles Wakalah and Mudarabah, with users delegating assets to validators as agents sharing variable rewards, and no fixed-return Qard-like arrangement is present, though formal Shariah classification has not been independently certified.
Rewards Structure83/100Rewards are variable and performance-based, influenced by stake amount, validator performance, and network competition, with no fixed APY promised and dual staking offering enhanced but still variable yields.
Documentation75/100Official documentation covers the Satoshi Plus architecture, validator election, slashing risks, and dual staking in reasonable detail, though a comprehensive risk disclosure document specifically for stakers is not confirmed in the research.
Shariah Alignment72/100The staking model avoids fixed returns and uses non-custodial delegation resembling recognized Islamic partnership structures, but the absence of independent Shariah certification leaves residual uncertainty around the formal classification of the mechanism.

Staking Summary: Core's Satoshi Plus staking is non-custodial, variable in rewards, and structurally resembles Wakalah and Mudarabah partnerships, but the absence of formal independent Shariah certification leaves some residual classification uncertainty.


Overall Assessment:

Core demonstrates meaningful Shariah alignment through genuine utility, credible leadership, non-custodial staking with variable rewards, and a riba-free protocol design, with the primary areas for improvement being more granular financial disclosures and formal independent Shariah certification of its staking mechanism.

Frequently asked questions
Is delegating Core to a stake pool permissible?

Delegating Core to a stake pool is generally permissible under Islamic finance principles, as it functions similarly to a cooperative arrangement where participants contribute resources to secure a network and share in the resulting rewards, without involving guaranteed fixed returns or interest-based mechanisms.

Do I need to purify my Core staking rewards?

Yes, a purification of 1.0-1.5% of profits is recommended for Core staking rewards to cleanse any potentially impermissible income that may arise from ambiguous or non-compliant activities within the network ecosystem.

Are Core staking rewards considered riba?

Core staking rewards are not considered riba in the classical sense, as they are generated through active participation in network validation and security rather than through a predetermined fixed return on a loan or debt obligation, making them closer to legitimate profit-sharing arrangements.

How do I calculate zakat on my Core holdings?

Zakat on Core holdings is calculated at the standard rate of 2.5% applied to the total market value of your Core holdings that have been in your possession for a full lunar year and meet or exceed the nisab threshold, which is typically benchmarked against the current value of 85 grams of gold or 595 grams of silver.

Can I gift Core to family members as a Muslim?

Gifting Core to family members is entirely permissible in Islam, as the transfer of lawful assets as gifts is a praiseworthy act encouraged by Islamic tradition, provided the asset itself is halal, which Core has been assessed to be with a score of 79.5 out of 100.
