It is recognised directly by the protocol and is commonly used to pay for network resources, compensate node operators and support the network’s security. The coin creates an economic connection between the people using the network and the people operating it. Users generate demand for transaction processing, computation and storage, while node operators provide the infrastructure required to satisfy that demand. A network coin is not logically required by every possible distributed system. A network could theoretically rely on external funding, voluntary participation or payments using assets created elsewhere. However, an open and permissionless network intended to operate as an independent and mission-critical system requires reliable incentives that do not depend on the continuing support of an outside institution. For this kind of network, a native coin provides one of the most direct ways to create a self-contained and circular economy. ## **The role of the network coin** The network coin can perform several connected functions. It can provide a common asset for pricing network resources, compensate node operators, support participation in consensus and contribute to governance. The exact combination varies between networks. A coin does not need to perform every possible function, and assigning too many responsibilities to it may introduce unnecessary complexity. Its most foundational role is to support the continuing operation of the network. Node operators must purchase and maintain hardware, use electricity and internet connectivity, store ledger data and monitor their systems. If operating a node imposes costs but provides no corresponding benefit, there may be insufficient participation to sustain a reliable global network. The network coin allows the protocol to reward operators without depending on a bank, government or company to process those payments. The reward can be distributed according to rules applied by the network itself. Users obtain the coin because they need network resources. Operators receive the coin because they provide those resources. This relationship gives the coin demand and allows it to transfer value between the two groups. ## **A circular network economy** A circular economy is created when the activity taking place within the network helps finance the infrastructure required to maintain that activity. Users submit transactions and pay fees or other network-level charges. The resulting income compensates node operators and may also support a treasury used for network maintenance and development. Node operators can then use or exchange the coins they receive. The coin returns to the wider economy, where other users can obtain it and pay for network resources. The process can continue without relying entirely on external funding: 1. Users create demand for the network 2. Demand for the network creates demand for its coin 3. Fees or taxes generate income 4. The income compensates node operators and funds network maintenance 5. The maintained network continues providing services to users The native coin connects each stage of this process. Its value reflects, at least partly, continuing demand for the network and confidence in its future operation. A network without a circular funding mechanism may depend on initial coin allocations, donations, corporate subsidies or government funding. These sources can support early development, but they may not provide a reliable long-term basis for operation. ## **A common unit for network resources** The network requires a consistent way to calculate the cost of processing transactions and compensating operators. A transaction may consume computation, storage and bandwidth. More complex transactions may require more resources than simple transfers. Using a single native coin allows the protocol to express these costs through one common asset. Every node can apply the same rules when determining whether a transaction has paid the required amount. If many independently governed assets were accepted, the network would need to compare their values. It would have to decide how much of each asset represented equivalent payment and update those relationships as market conditions changed. A native coin avoids much of this complexity. The protocol defines network costs in its own unit, while markets outside the core protocol determine the coin’s value relative to other assets. Users who prefer another asset can exchange it for the native coin before submitting a transaction. Wallets and applications may automate this process so that the conversion is not visible as a separate action. Node operators can similarly exchange the coins they receive for whichever assets they prefer. The protocol does not need to implement every individual preference at the network level. ## **The network coin and node compensation** Node compensation must be reliable enough to support continuing participation. If the value of the rewards falls below the cost of operating a node, some operators may leave. A decline in participation can reduce decentralisation, resilience and security. If the rewards are unnecessarily high, users may pay excessive fees or the network may create more coins than are required. This can transfer value towards operators and affect the coin’s supply. The network must therefore balance adequate compensation against the cost imposed on users and coin holders. A native coin makes it possible to calculate and distribute rewards through the consensus process. The protocol can determine which operators performed the required work and allocate compensation according to its rules. This reduces dependence on an external payment administrator. Operators do not need to submit invoices to a company or wait for a central organisation to approve payment. For a permissionless network, this independence is important. Anyone who meets the protocol’s requirements can potentially participate and receive compensation without entering a private contract with a central owner. ## **The network coin and consensus** A consensus mechanism allows nodes to agree on the accepted state of the ledger. The network coin can support this process by attaching an economic cost to participation and misconduct. In a proof-of-stake network, participants commit network coins as part of the consensus mechanism. Their stake may influence their opportunity to validate transactions or participate in determining the accepted ledger state. The coins placed at risk create an incentive to behave according to the protocol. A participant that acts maliciously may lose some or all of its stake, depending on the network’s rules. The security of this approach depends partly on the value and distribution of the network coin. If acquiring a large proportion of the coin is inexpensive, an attacker may be able to obtain enough influence to disrupt consensus. If ownership becomes concentrated, a small number of holders may exercise substantial control even when the market value of the coin is high. A network coin is not the only conceivable way to organise consensus. Proof-of-work networks use computational resources rather than coin holdings as the direct basis of participation. However, these networks still commonly use a native coin to compensate operators for the resources they contribute. The coin therefore remains important even when it is not itself the principal resource used to determine consensus influence. ## **The network coin and governance** A network coin can also contribute to governance. Holders, stakers or people who have paid fees and taxes may participate in decisions about protocol parameters, software upgrades and treasury expenditure. Coin-based governance provides one response to the Sybil-resistance problem. Creating additional wallets does not automatically create additional coins, so an individual cannot obtain more voting power merely by presenting themselves as many participants. However, coin-based governance can concentrate influence among large holders. Using the network coin for governance is therefore a possible function rather than an unavoidable requirement. A network can adopt other governance methods or combine several measures of participation. The important point is that a native coin provides an asset whose ownership and use are visible to the network and connected to its economic activity. Using independently created tokens for network governance would introduce additional complexity. The network would need to decide which tokens qualified, how their voting power should be weighted and whether their distributions represented legitimate participation. A token community could modify its supply or governance rules to gain additional influence over the underlying network. A native coin avoids this conflict by providing one protocol-level asset governed as part of the network itself. ## **Could tokens replace the network coin?** A programmable Web3 network may contain many fungible tokens. It is therefore reasonable to ask whether these tokens could pay transaction fees and compensate node operators instead of a native coin. One approach would be for the network to accept a list of approved tokens. Users could select one of those tokens when paying for network resources, and node operators would receive the selected asset. This would give users more payment options, but it would make the protocol responsible for evaluating assets governed by separate communities. The network would need to determine which tokens were sufficiently reliable. It would also need to establish how much of each token represented adequate payment for a transaction. Token prices can change rapidly. A fee that was sufficient when the transaction was prepared might be insufficient when it was processed. The network would need reliable pricing information and a method for updating accepted values. Obtaining this information could require pricing oracles. These would introduce external data into a mission-critical part of the network. If the data were manipulated, users might obtain large amounts of network capacity for inadequate payment. The governance of approved tokens would also create continuing work. New tokens would request inclusion, existing tokens might need to be removed and disputes could arise over which communities received access. A single native coin avoids the need to govern a changing list of payment assets at the core protocol level. ## **Token governance risks** Tokens are generally controlled by smart contracts and application-level governance. Their rules may be changed by administrators, token holders or other authorised participants. A token used for node compensation could therefore be altered independently of the network. Its community might increase the supply, restrict transfers or otherwise change its economic properties. If node operators depend on that token, decisions made by an external token community could affect the reliability of the entire network. The token might also fail because of a contract error, loss of backing or collapse in demand. If several tokens were accepted, the network would need to detect such failures and remove the affected assets. These problems are manageable at the application level because users can decide whether they trust a particular token. They are less desirable at the protocol level, where every application depends on the continuing operation of the network. The asset responsible for funding network operation should therefore be governed with the network rather than by an independent application community. ## **Node operator selected tokens** Another possibility would be to allow each node operator to decide which tokens they were willing to accept. This avoids requiring the protocol to maintain one approved list, but it fragments the transaction market. A user paying with a particular token would need to find operators that accepted it. Some operators might demand a higher fee than others, and the network would need to determine how transactions paid with different assets entered the shared consensus process. The resulting complexity could undermine the uniform application of network rules. It could also concentrate transaction processing among operators accepting the most popular tokens. Node operators are still free to prefer different assets, but this preference can be handled after compensation. The protocol pays them with the native coin, and they exchange it according to their own requirements. This preserves a common protocol-level unit without preventing individual financial choice. ## **Wallet token conversion** Users do not necessarily need to experience the native coin as a barrier to network access. A wallet can determine how much network coin is required, exchange another token into that amount and submit the transaction. The conversion can occur as part of the user’s broader transaction process. A user may appear to pay with a token even though the underlying network receives its native coin. The complexity is handled by the wallet, exchange or application rather than by the core protocol. This separation is valuable because wallet software can compete and improve without requiring a network-wide upgrade. Different wallets can offer different methods for obtaining the coin, sponsoring fees or managing balances. The network retains a simple and consistent compensation mechanism while users receive greater flexibility at the application level. ## **Could external funding replace the network coin?** A network could attempt to compensate node operators through external funding. Governments, companies, charities or other institutions could contribute money to a treasury, which would then pay the operators. For example, a government could collect revenue through taxation and use part of it to fund the network. The network might then provide low-cost or free transactions to users. The main problem is reliability. No external institution is permanently required to continue providing the funding. A government may change its priorities, a company may become insolvent and donors may lose interest. Political disagreements may also lead one country or region to stop contributing while its residents continue using the network. This creates the possibility of free-riding. Some participants benefit from the network without contributing towards the cost of operating it, while others carry a disproportionate share of the expense. External funding may also fail to grow in line with the network. If usage expands, the cost of computation, storage and operation may increase. The external funding source may remain fixed or decline. A network intended to become mission-critical should avoid depending entirely on financial decisions made outside its own protocol. ## **External funding and control** External funding can also create concentrated influence. An institution providing a large proportion of the network’s operating income may expect control over governance, transaction rules or access. Even when the institution has no formal authority, the threat of withdrawing funding can affect network decisions. This dependence would weaken the network’s claim to operate as an independent and decentralised system. A native coin does not automatically remove concentrated power. Large holders, founding organisations and dominant node operators may still exercise substantial influence. However, a coin-based circular economy gives the network a mechanism for funding itself through its own users and activity rather than through a single external sponsor. External contributions can supplement this system without becoming the sole basis of continued operation. ## **Could node operation be voluntary?** Some networks may rely on volunteers or organisations that operate nodes because they benefit indirectly from access to the ledger. Businesses may run nodes to verify their own transactions, developers may operate infrastructure for their applications and community members may participate because they support the network’s objectives. This voluntary activity can be valuable, but it may not be sufficient for every network role. Participants may be willing to verify information for themselves without supplying the capacity required to process transactions for a global population. Voluntary participation can also decline during periods of high cost or low interest. A network that supports economically important applications requires incentives capable of sustaining operation across changing conditions. A native coin provides a direct reward for contribution rather than relying entirely on indirect benefits or goodwill. The need for a coin is therefore stronger when operating the network imposes substantial and continuing costs. ## **Networks with limited economic requirements** Not every Web3 network has the same requirements. A small or permissioned network may know its operators in advance and fund them through contractual arrangements. A network maintained by a consortium of institutions may divide operating costs between its members. In that environment, a native coin may be unnecessary. The argument for a network coin applies most strongly to open and permissionless networks where participants do not know one another, no central organisation is permanently responsible for funding operation and anyone meeting the technical requirements can contribute infrastructure. For these networks, a native coin creates an internal mechanism for coordinating users and operators without requiring prior personal or institutional relationships. ## **The advantages of a native coin** A network coin provides a common asset that is directly connected to the protocol. It can be used without requiring the network to evaluate independently governed tokens, external currencies or funding institutions. Its rules can be designed around the needs of the network. The coin can compensate operators, price resources and support security without also attempting to meet every requirement of a community medium of exchange. The native coin also creates an observable economic relationship between use and operation. Demand for network resources supports demand for the coin, which gives the network a source of value with which to reward contributors. This design is simpler than accepting many tokens at the protocol level and more self-contained than relying on external funding. Its simplicity becomes increasingly important as the network grows. A globally adopted ledger may become mission-critical for businesses, communities and financial applications. Each additional dependency creates another possible source of failure. ## **The risks created by a network coin** The network coin also introduces important risks. If its value declines substantially, operator compensation may become inadequate. If ownership becomes concentrated, a small number of holders may influence consensus or governance. If the coin appreciates rapidly, users may find it expensive to acquire and increasingly attractive to store. The network may also become dependent on speculative demand rather than productive use. A high market price can support security in the short term while encouraging concentration and volatility over the long term. The coin must therefore maintain enough demand to support node operation and security while remaining sufficiently available for users to access the network. Its supply, distribution, carrying costs and incentive mechanisms must be designed around this balancing problem. The existence of these challenges does not remove the need for a common network-level asset. It means that creating the asset is only the first step. The network must also determine what responsibilities the coin should perform and what outcomes its economic design should achieve. For an open and permissionless Web3 network, the native coin is the most direct mechanism for creating a circular economy, compensating node operators and maintaining independence from external funding.
