In every century, there is a technological breakthrough that
catapults mankind light years ahead of its time. The discovery of fire, the
invention of the wheel, steam engines, and recently the internet have improved
life for humanity.
Just when we thought that it couldn’t get any better,
blockchain came into the picture in 2008 flipping the script for virtually
every facet of human life.
Blockchain technology brought with it DApps, DeFi, DEX, and
multiple use cases, yet for all of its innovation the technology is far from
perfect. Improvements in energy consumption, scaling, and governance will be a
welcome development for the technology.
Blockchain Almighty
After Satoshi Nakamoto invented the first blockchain in
2008, the technology took off like a rocket to the moon. In technical terms, a
blockchain is a digital ledger of transactions that are held together in
“blocks” that are linked together using cryptography.
Every block contains the cryptographic heart of the former
block and is virtually unalterable except through the use of forks.
This technology is at the heart of cryptocurrencies, NFTs,
decentralized finance, and decentralized exchanges amongst others.
Blockchains have been deployed in the educational system to
keep immutable records for grades and have seen usage in art and music. Through
the benefits of blockchain, artists can make money from their artworks and keep
track of any future sale of their artworks.
Blockchain promises so much more, including use for free and
fair elections and even revolutionizing the world’s financial system as we know
it.
The Downsides of Blockchain
Perfection is almost impossible to attain and with over $2
trillion invested in the ecosystem built on the blockchain, a lot is left to be
desired. Critics of blockchain technology are quick to point out its high
energy consumption rates. The high energy consumption is a result of the
immense amount of computing power that is used to secure blockchain networks.
Bitcoin alone uses more energy than Argentina and the use of fossil fuels
raises environmental concerns.
The lack of regulation of the sectors built on the
blockchain architecture is a breeding ground for scams, market manipulations,
hacks, and Ponzi schemes. Already, cryptocurrency scams have cost investors
over $20 billion since its inception.
Scaling is a fundamental problem in blockchain because as
the network grows it becomes difficult for the decentralized system to handle
the number of transactions. This leads to slower transaction speeds and the
halting paradox.
12 years after its launch, blockchain technology remains
complex for the average person. It takes quite a bit of study to be able to
grasp the inner workings of the tech to fully appreciate it.
On The Flipside
Critics of blockchain hold the conception that blockchain
solutions are worse than the systems they try to replace.
The volatility of cryptocurrencies and their increasing
usage for money laundering and illicit transactions put a tent on the
technology
The Solution
For blockchain to assume the role of the almighty, it must
be energy efficient. Blockchains should leave the energy-intensive
Proof-of-Work consensus model for the greener Proof-of-Stake consensus.
The technology should look inwards to solve the scalability
problem that has always been a thorn in its side.
A proper governance mechanism should be put in place to
regulate the ecosystem despite its decentralized nature and the concept and
interfaces should be made more user-friendly. IOTA, for example, is utilizing
an improved ledger system.
