Description
These assets function as the native currency of a Layer-1 blockchain. They were created primarily to facilitate the transfer of value across a decentralised network without the need for intermediaries such as banks or payment processors. Users typically hold these assets to store value outside of the traditional financial system, hedge against inflation, or make peer-to-peer payments.
Risks
Volatility and Valuation Models. The value of these assets is not derived from traditional financial metrics such as revenue, dividends, cash flow, or interest rates. Unlike equities or bonds, there is no underlying balance sheet or earnings report to anchor the valuation. Instead, value depends heavily on network adoption, security hashrate, public perception, and speculative supply and demand dynamics. Consequently, prices can be extremely volatile and may react sharply to news cycles, macroeconomic shifts, regulatory announcements, or changes in investor sentiment. It is common for these assets to experience significant percentage fluctuations within a single trading day.
Consensus Mechanism Risks. Many payments-focused blockchains utilise a Proof-of-Work (PoW) consensus mechanism. While robust, these networks are susceptible to a '51% attack'. This occurs if a single malicious actor or a colluding group of miners gains control of more than half of the network's mining power. If successful, the attacker could disrupt the network, prevent new transactions from gaining confirmations, reverse transactions completed while they were in control, and double-spend tokens. Smaller PoW networks face a significantly higher probability of such attacks.
Scaling and Transaction Costs. These networks often prioritise security and decentralisation over transaction throughput. During periods of high global demand, the network's waiting area for unconfirmed transactions (mempool) may become congested. This results in a competitive fee market where users must pay increasingly higher fees to have their transactions prioritised by miners. This congestion can lead to significant delays in transaction processing times and a sharp increase in transaction fees. Users may find it prohibitively expensive or slow to move assets when they need them most, particularly during periods of market panic.
Environmental Impact and Regulatory Scrutiny. PoW networks consume vast amounts of electrical energy to secure the ledger. This high energy consumption has led to criticism from environmental groups and policymakers. There is a tangible risk of regulatory crackdowns, carbon taxes, or outright bans on mining operations in various jurisdictions. Such regulatory interventions could destabilise the network by reducing the security hashrate or limiting the asset's integration with the traditional financial system and ESG-focused institutional investors.
Limited Upgradability. Due to their decentralised nature and reliance on broad consensus among thousands of independent node operators for protocol changes, these networks can be slow to upgrade. This rigidity may prevent the protocol from adapting to new technical threats or implementing desirable features found in newer, more agile blockchains. This could lead to a gradual loss of market share and value over time as users migrate to more technologically advanced alternatives.
Finality Risk. Transactions on PoW blockchains are probabilistic rather than deterministic. While a transaction may appear confirmed after being included in a block, there is always a theoretical risk of a 'chain reorganisation' where a competing chain with more accumulated proof-of-work becomes the definitive chain. This event could result in previously confirmed transactions being reversed or erased from the ledger.
