When Will Blockchain Become a Truly Mainstream Technology?

For those outside of the tech sphere, blockchain can be one of the most confusing technologies to fully comprehend.

It is a philosophy, a way of understanding ownership, a method of storing data, a network of computers, a means by which to keep and maintain records. In essence, blockchain is a lot of things at once.

But the truth is that blockchain is really a lot simpler than it sounds.

Blockchain technologies are digital ledgers, keeping records of financial data online, rather than in physical books or files. These ledgers are maintained simultaneously across thousands of computers rather than being held by one single institution.

The crucial part: once data is recorded on a blockchain, it cannot be altered without network-wide consensus.

This means that any transaction – whatever was bought or sold or how much money changed hands – is imbued with total transparency and accountability. 

It may not sound ground-breaking, but this idea is revolutionary, especially in environments where trust might otherwise be absent. It also means that parties can engage in direct transactions without the need for intermediaries.

It also means that buyers and sellers can transfer value, track supply chain movements and verify the ownership or providence of a product without having to rely on centralised authorities.

In sum, blockchain might sound complex, but it has the ability to make the global economy as we know it far, far more streamlined.

Blockchain's historic barriers to widespread adoption

Despite all its theoretical promise, though, blockchain has struggled to achieve mainstream penetration that was expected of it. Mainly, this has come down to some pretty fundamental technical challenges.

Wesley Crook is CEO of FP Block, a blockchain engineering firm. For him, blockchains issues can be boiled down to three main things: complexity, scalability and interoperability.

"Developers often spend months rewriting code for different blockchains, systems buckle under real-world demand and projects are locked into a single chain that may not meet their needs over time," he explains.

The fragmentation across multiple blockchain ecosystems has created some severe vulnerabilities in blockchain security, as well as problems with properly integrating data between systems.

Wesley notes that, since 2021, more than US$2.8bn has been lost through bridge exploits, which are the tools designed to connect different blockchains to one another.

"This highlights the fragility of current interoperability solutions. Instead of unlocking growth, poor design has exposed projects to massive security risks," he says.

Why blockchains make companies more competitive

Despite the issues that blockchain is still to overcome, companies remain very interested in the technology's potential.

Just this week, global payments group Swift announced its plans to create its own blockchain infrastructure, facilitating transactions between global banks.

The Belgium-headquartered cooperative, which serves more than 11,500 banks and financial institutions worldwide, plans to partner with Bank of America, Citigroup and NatWest to develop this new shared digital ledger.

Among other things, the system will support transactions in tokenised products, including stablecoins.

Swift has stated that the new blockchain would "record, sequence and validate transactions and enforce rules through smart contracts", while making "instant, always-on cross-border transactions possible at unprecedented scale".

The move represents a direct response to competitive pressure from the US$300bn stablecoin industry.

Dominated by issuers Tether and Circle, stablecoins allow users to transfer funds directly without intermediaries, threatening Swift's traditional role in cross-border payments.

In a report published earlier this year, McKinsey & Company revealed that stablecoins represent "a direct challenge to traditional global payments rails" like Swift, because legacy systems can take up to five days to complete transactions and involve multiple intermediaries.

Swift is responding to this, well, swiftly. The fintech firm is collaborating with blockchain technology company Consensys, led by the Co-Founder of Ethereum, Joseph Lubin, to create a prototype ledger.

Testing with partner banks will determine which transactions, currencies and country corridors should be prioritised for the initial rollout.

The initiative follows on from a piece of US legislation passed in July aimed at regulating the stablecoin industry, which has encouraged major banks including JPMorgan Chase and Citi to explore launching their own dollar-pegged tokens.

Last week, nine European banks including UniCredit, ING and Danske Bank announced plans to jointly launch a euro-denominated stablecoin by the second half of 2026.

How blockchain can go mainstream

According to Wesley, successfully implementing a blockchain requires foundational discipline, rather than iterative experimentation.

His firm is regularly enlisted to rescue projects that have collapsed under operational stress, providing first-hand evidence of how costly retroactive fixes become compared to proper initial architecture.

"Too many projects fail because they were built on shaky foundations", he explains. "We apply mature DevOps and DevSecOps practices, rigorous code audits, and compliance-minded architecture to ensure projects are reliable, scalable and future-proof."

FP Block's flagship framework, KOLME, addresses scalability constraints by allowing each application to operate on its own high-performance blockchain whilst maintaining interoperability with major ecosystems including Ethereum, Solana and Cosmos.

Wesley and the team at FP Block believe that the convergence of proper engineering standards with cross-chain interoperability will prove decisive for blockchain's role in global infrastructure.

"Just as the internet became the backbone of communication and commerce, blockchain is on track to become the backbone of trust and value exchange", he argues.

There are still creases to be ironed out, but once these challenges are overcome the technology could go truly mainstream.

"We believe interoperability will be the key to unlocking its mainstream role," Wesley says.

"Once enterprises and developers can build applications that work seamlessly across ecosystems, blockchain will shift from experiments and pilots to critical infrastructure in the global economy."
