With smart contracts, a program enforces the contract built into the code. Once a smart contract is deployed, it cannot be updated. End clients interact with a smart contract through transactions. Such transactions with a smart contract can invoke other smart contracts. These transactions might result in changing the state and sending coins from one smart contract to another or from one account to another. Bitcoin maximalists believe that these other cryptocurrencies—called altcoins —are unnecessary and inferior.
Key Takeaways Bitcoin maximalists believe that Bitcoin is the only digital asset that will be needed in the future. Bitcoin maximalists believe that all other digital currencies are inferior to Bitcoin. However, Bitcoin's scalability issue has led to the development of other blockchain networks that can handle an increased volume of transactions.
Bitcoin maximalists would likely argue that Bitcoin's shortcomings can be solved, but the investment in alternative blockchains continues to grow. Understanding Bitcoin Maximalism Although Bitcoin may not have been the very first attempt at a decentralized cryptocurrency, it has unquestionably been the most successful thus far. Bitcoin maximalists hold the belief that the Bitcoin network will provide everything that investors want in a digital currency in the future.
In this way, maximalists are unapologetically in favor of or at least in agreement about the inevitability of a Bitcoin monopoly at some point in the future. Ethereum developer Vitalik Buterin commented on the idea of Bitcoin maximalism in The idea that an environment of multiple competing cryptocurrencies is undesirable, that it is wrong to launch 'yet another coin,' and that it is both righteous and inevitable that the Bitcoin currency comes to take a monopoly position in the cryptocurrency scene.
Bitcoin maximalists often use "network effects" as an argument, and claim that it is futile to fight against them. The distributed ledger is beneficial since it allows the sharing of transactions by sending recorded copies of the data to participants within the shared network. As a result, this transparency helps to increase security and prevent fraud.
If a bad actor changes one portion of the blockchain, other participants who have copies of the original transactions can determine what was changed by the fraudster and reinstate the legitimate transaction. However, Bitcoin's BTC popularity has ushered in the age of cryptocurrencies leading to the creation of hundreds of other digital currencies. Many of these cryptocurrencies are built from the basic Bitcoin structure in some way or another, while other digital currencies are based on blockchain technology but not necessarily on Bitcoin's network specifically.
In other words, the distributed ledger of Bitcoin has been modified so that it can be used for other purposes and not merely a peer-to-peer cash payment system as was originally intended. Companies and governments can create private blockchain networks in which only a select number of participants are allowed access to the network once they've been verified or authenticated.
These private blockchains can be permissioned or semi-permissioned networks, which allow a mixture of both public and private characteristics. Within these networks, there are designated permissions granted to certain participants allowing them to perform only specific activities on the network. The network might also impose restrictions on what functions are allowed by participants, such as read-only and editing access. An example of a semi-private blockchain network would be a local government that allows certain taxpayers and businesses access to legal titles and record-keeping while restricting access to those records for the general public.
While public blockchains are decentralized, meaning they have no centralized authority with oversight power, private blockchains have a centralized entity, such as a government or business, that manages and controls the network. The use of private, semi-private, and permissioned blockchains runs contrary to the purposes of cryptocurrencies in that they should be open, transparent, and have no centralized governance.
Reasons for Bitcoin Maximalism The maximalists are a vocal group of Bitcoin supporters that back Bitcoin above all other digital currencies. Below are some of the reasons why maximalists believe Bitcoin will render all other cryptos ineffective. Bitcoin's Network Many Bitcoin maximalists today support the idea that the success of a digital currency is dependent upon the underlying blockchain network.
It is common to hear the idea that, although other digital currencies may offer modifications upon the original Bitcoin premise, which are designed to address issues inherent in the Bitcoin network, the ultimate marker of success is the length and strength of a blockchain. Because Bitcoin's underlying network is as strong as it is, the thinking goes, and because features of any particular digital currency can be freely co-opted by another digital currency, the network itself is the most important factor.
Maximalists may point to the dominance of Bitcoin and Bitcoin cash in the leaderboard of digital currencies by market cap as evidence of this principle. However, the altcoins maintain a higher value because of their connection to the Bitcoin network. The wealth, the size of the user base, and the history of success are features, which set the Bitcoin network apart from other blockchains.
Bitcoin Is Well-Established Another argument for the maximalist perspective is the principle that new financial instruments must face a high barrier to building investor trust. Even as digital currencies have become exponentially more popular, there are still many major financial institutions and individual investors that prefer to bow out of the market.
Bitcoin maximalists believe that the process of integrating digital currencies fully into the world of mainstream finance and investing will be a slow one. As a result, outsiders are likely to pay the most careful attention to the oldest, most popular, and most established networks. In the case of digital currencies, the most established is Bitcoin. With dozens of new, untested digital currencies emerging, Bitcoin has a strong advantage in that it has proven reliability and success.
When other cryptocurrency networks suffer from hacks or other negative publicity, Bitcoin maximalists tend to see this as further evidence in support of their argument. Bitcoin's Trading Influence on Altcoins A final argument for the maximalist philosophy has to do with diversification within a cryptocurrency or broader portfolio. Because the price of Bitcoin tends to influence the price of the altcoin world more broadly, investing in altcoins may be a questionable way of diversifying one's cryptocurrency holdings.
The argument then follows that investors would be better off investing in a best-of-breed asset, such as Bitcoin, instead of risking their money by investing in other coins or tokens. However, Bitcoin's rise in price has not always driven altcoins higher but maximalists might argue that's due to the inferior quality of altcoins.
