Cryptocurrencies and their functioning without Internet: a detailed analysis

Cryptocurrencies and the global network are intrinsically linked, as digital assets rely on web infrastructure to ensure secure transactions and maintain the integrity of the blockchain. Given the possibility of interruptions in Internet access, concerns arise about the viability of cryptocurrencies in such scenarios.

This article explores the close relationship between cryptocurrencies and the Internet, the possible causes of disruptions in global connectivity, and the alternatives for the operation of digital coins without access to the network. As digital assets gain relevance, understanding their ability to adapt to possible Internet disruptions becomes crucial for the future of the financial ecosystem.

The fundamental role of the Internet in the cryptocurrency ecosystem

Cryptocurrencies emerged as a natural extension of the digital age, embodying the principles of decentralization and facilitating borderless transactions. The global network has been the foundation upon which cryptocurrency systems have been built, playing a crucial role in their expansion and adoption.

Digital assets represent a form of value that transcends geographical boundaries, perfectly aligning with the interconnected and global nature of the Internet. The network acts as the medium through which cryptocurrency transactions are conducted, allowing individuals from different parts of the world to engage in direct exchanges without intermediaries.

Blockchain technology and its dependence on global connectivity

Blockchain technology, which underpins cryptocurrencies like Bitcoin, functions as a distributed ledger that meticulously documents every transaction made on the network. These operations are validated by a network of nodes geographically dispersed around the world. However, the crucial element that enables communication and validation among these nodes is Internet connectivity.

The decentralized nature of blockchain technology implies that no entity has exclusive control over the network. Instead, it relies on a consensus mechanism among the nodes to maintain the integrity of the ledger. This mechanism requires nodes to independently verify and agree on the validity of transactions.

In this intricate network of peer-to-peer transactions, the Internet plays a fundamental role in ensuring that nodes can communicate seamlessly. Each node must have access to the network to receive and transmit transaction information to its peers. Without this global network of interconnected nodes facilitated by the Internet, the entire decentralized system on which cryptocurrencies rely would be compromised.

The blockchain and the global network

The global network of nodes operating on the blockchain ensures several critical attributes of cryptocurrency transactions. The blockchain guarantees transparency, as each operation is publicly recorded and visible to any interested party.

Contributes to security, as the distributed nature of the ledger makes it resistant to tampering attempts or cyber attacks.

It maintains immutability, as once a transaction is recorded on the blockchain, it becomes a permanent part of the history and cannot be altered.

This interconnected network of nodes allows for direct transfers of digital assets between peers. When a cryptocurrency user initiates a transaction, the information is transmitted across the network and the nodes collaborate to validate and add the operation to the blockchain. This process occurs without relying on intermediaries, such as traditional financial institutions or payment processors.

Hypothetical scenario: cryptocurrencies without internet access

While a total global Internet outage is highly unlikely, there have been cases where governments have restricted access to the network within their jurisdictions for various reasons. These localized outages have had significant economic consequences and highlight the vulnerability of cryptocurrencies in the absence of connectivity.

A global Internet disruption would temporarily paralyze the cryptocurrency ecosystem. Transactions, which rely on the network for their confirmation and recording on the blockchain, would be unable to execute. The decentralized nature of cryptocurrencies requires a coordinated effort worldwide through the Internet for mining new blocks and maintaining the integrity of the chain.

Some cryptocurrencies could show some short-term resilience without the Internet, as long as alternative technologies could facilitate global connectivity and coherence. For example, Bitcoin transactions could continue if the operation data managed to reach the blockchain, regardless of the medium used.

Potential technologies to drive cryptocurrency transactions without the Internet

SMS-based operations

Short message services (SMS) have emerged as a promising avenue to facilitate cryptocurrency transactions, especially in regions with limited access to conventional Internet. This innovative approach allows users to initiate operations via standard text messages, with subsequent confirmation and recording on the blockchain through connected services.

The mechanism behind SMS-based cryptocurrency transactions is simple. A user drafts a message with the necessary details of the operation, which is then sent to a designated service provider. This provider acts as an intermediary, bridging the gap between the user and the blockchain network. Upon receiving the SMS, the provider validates the transaction and transmits it to the blockchain on behalf of the user. Once confirmed, the operation is permanently recorded in the immutable ledger of the blockchain.

A notable example of SMS-based cryptocurrency solutions is Machankura, which has been instrumental in empowering people in Africa facing connectivity issues to participate in transactions with Bitcoin. Through Machankura, users can send and receive Bitcoin seamlessly via SMS, effectively bypassing the limitations of unreliable or nonexistent Internet access.

While SMS-based transactions offer a possible alternative in situations where traditional Internet connectivity is unreliable or unavailable, they are not without limitations. The speed of processing operations and the reliance on intermediaries for validation remain areas of concern that must be addressed to improve the viability of SMS-based cryptocurrency transactions.

Satellite-based operations

Satellite technology presents an alternative means to transmit cryptocurrency transactions, particularly valuable in remote and underserved areas where Internet connectivity remains a challenge. In this approach, users utilize specialized satellite receivers to facilitate the processing and recording of cryptocurrency operations on the blockchain.

Gate, a leading platform in the cryptocurrency space, has been a pioneer in implementing satellite-based cryptocurrency transactions. This innovative technology allows users to send and receive Bitcoin transactions via satellite signals, effectively eliminating the need for traditional Internet access.

The mechanics of satellite-based cryptocurrency transactions rely on the transmission of operational data to satellites orbiting the Earth. These satellites, in turn, relay the data to ground stations that seamlessly integrate into the blockchain network. Once a transaction is confirmed, it becomes a permanent part of the blockchain ledger.

Satellite transactions not only provide an alternative for users in remote locations, but they also enhance the overall resilience of cryptocurrencies by diversifying connectivity means. However, it is necessary to address challenges such as the initial cost of satellite receivers and the need for specialized infrastructure for satellite transactions to become more accessible and cost-effective for a broader user base.

Radio-powered transactions

Radio technology represents another interesting option for keeping cryptocurrency transactions in scenarios where traditional Internet infrastructure is unreliable or is deliberately disrupted. In a notable experiment conducted in 2019, two Bitcoin developers successfully demonstrated the feasibility of processing Bitcoin Lightning payments using radio waves. This innovative response was designed to counter possible censorship and showed the adaptability of cryptocurrencies.

The concept underlying radio-driven cryptocurrency transactions involves the use of radio waves to transmit operation data between users and nodes within a mesh radio network. Transactions are validated and added to the blockchain ledger, reflecting the conventional process observed in Internet-based transactions.

While radio transactions offer a means of resilience against Internet interruptions, they are not without limitations. The technology tends to be comparatively slower in processing operations when compared to traditional Internet-based methods. Additionally, specialized radio equipment is essential for both transmitting and receiving transactions, and the cost and accessibility of that equipment pose inherent challenges that require further refinement and improvements in accessibility.

Challenges of Using Alternative Technologies

Dependence on Internet for registration and mining

Alternative technologies have proven to be promising for enabling cryptocurrency transactions without access to traditional Internet. However, a critical challenge lies in the ongoing dependence on the network to record transactions and perform mining activities. While these technologies can initiate and transmit operations through unconventional means, they invariably rely on the Internet to record these transactions on the blockchain and facilitate the essential process of mining.

In a scenario of total Internet disruption, where the global network is completely inaccessible, alternative technologies may struggle to coordinate transaction recording and the incorporation of new blocks into the chain. This poses a formidable obstacle to the smooth operation of cryptocurrencies, as the lack of a unified Internet connection disrupts the essential consensus mechanisms and validation processes that cryptocurrencies rely on.

Blockchain fragmentation

The absence of a global Internet connection in an environment that heavily relies on alternative technologies would lead to a fragmented blockchain landscape. Each disconnected network or node would possess its own isolated copy of the blockchain, separate from the broader network of nodes. This fragmentation creates several challenges, primarily related to transaction reconciliation and blockchain maintenance.

Operations initiated within a fragmented network may not be easily translatable or recognized by other isolated nodes. Maintaining a single and functional blockchain becomes a formidable task. In such a fragmented environment, the risk of certain transactions being discarded during the block addition process increases, as the different segments of the blockchain may not synchronize with each other.

Technical Limitations

While alternative technologies offer innovative solutions to avoid dependence on the Internet in cryptocurrency transactions, they come with their own technical limitations. These constraints have significant implications for the speed, cost, and reliability of operations, which can affect the overall user experience.

For example, radio transactions, while promising, have significant disadvantages. They tend to be notably slower compared to traditional Internet-based transactions, which can hinder the speed and efficiency of cryptocurrency operations. Additionally, the requirement for specialized radio receivers presents accessibility challenges, as the cost and availability of such equipment may limit their widespread adoption.

The need for Internet-independent cryptocurrencies

The improbability of a global Internet interruption

The total shutdown of the Internet worldwide is an event of extremely low probability, given the widespread dependence on the network for countless aspects of modern life, including communication, commerce, and information exchange. The intricate web of global connectivity makes a simultaneous and total disruption an almost impossible fact.

However, it is essential to consider scenarios where access to the Internet is restricted for various reasons. The cases of localized Internet outages, while not occurring worldwide, have demonstrated the potential for disruptions in digital communication. These localized incidents underscore the need to develop robust, Internet-independent solutions for the cryptocurrency ecosystem.

Importance of innovation in cryptocurrencies

The cryptocurrency development community plays a central role in addressing the imperative of having cryptographic solutions independent of the Internet. While the global network remains robust, it is essential to allocate resources to research and development initiatives that strengthen the cryptocurrency landscape against unforeseen challenges, including potential Internet disruptions.

Innovations in the field of cryptocurrencies must extend beyond the digital environment and explore alternative technologies and methods that enhance resilience. The ability to adapt to changing circumstances and maintain functionality in diverse scenarios will be crucial for the growth and continued adoption of cryptocurrencies in the future.
