The blockchain is often at the center of discussions about its many potential applications, but several misconceptions persist about it. Although it is perceived as innovative and revolutionary, many myths circulate, creating confusion that can hinder its adoption by businesses. This article examines five of these myths and demystifies the false ideas surrounding this complex technology.
The myth of immutability
The concept of immutability is often invoked when it comes to blockchain, referring to its ability to record data in an unalterable manner. However, studies show that it is possible to make changes to a blockchain. For example, it is possible to recalculate the chain to erase and recreate its history or to duplicate it to preserve old states while making modifications.
Permissioned blockchains also represent a sensitive area, as they typically have fewer nodes than public blockchains. This makes them more vulnerable to attacks. The idea that the technology itself is responsible for security is misleading. In reality, the protection of data depends on how the network is designed and managed.
The myth of disintermediation
Another common myth is that blockchain enables a completely decentralized approach, thus eliminating all intermediaries. Although the technology facilitates direct communication between parties, it does not necessarily eliminate the need for intermediaries. In reality, new intermediaries can enter the network, while others may disappear. Users still have to navigate an environment where trust is necessary, even in blockchain networks.
The myth of zero trust
In a blockchain, users exchange value without knowing each other, which might lead to the belief that it is a zero-trust system. However, participants must trust the operation of the network and the cryptography that underpins it. Thus, trust is always present at different levels, which refutes the idea that blockchains completely eliminate the need for trust between users.
The myth that blockchains are “truth machines”
Blockchain is often viewed as the perfect solution for ensuring transparency and the provenance of transactions, both in the physical and digital world. While the technology offers impressive traceability, its ability to prevent fraud is not guaranteed. No technology, including blockchain, is capable of completely eliminating attempts at fraud. To ensure tangible proof of origin, a complementary approach is necessary around the blockchain.
The myth of transparency
The issue of transparency in blockchain networks is also complex. Although transparency is often cited as a major advantage, for many businesses, it can also pose significant problems. Data privacy remains a challenge, as all information on a typical blockchain can be accessed by all participants. Before making a decision regarding the implementation of blockchain, it is crucial for businesses to carefully assess their privacy needs.
