Blockchain 3.0: Beyond Bitcoin and First-Generation Distributed Ledgers, From Aion to Cardano, EOS and Zilliqa

Similar to the internet, which was at one point underrated in the early 1990s, it can be difficult to accurately predict the impact that blockchain technology will have on businesses in the coming decade. Regardless of the regulatory uncertainty, a handful of businesses are working relentlessly behind the scenes – building applications or streamlining an existing process in a bid to discover a use-case that derives value from a distributed ledger technology.

Despite the recent global financial turmoil paired with the pandemic stirred by the Covid-19 virus, the cryptocurrency industry is growing, despite market volatility. Developers around the world are building on blockchain and this trend is certainly not slowing down, as developers are embracing the constantly evolving technology. Just like running traditional IT solutions, there are several development phases for blockchain. We are currently in the third phase of innovation, blockchain 3.0.

The first generation of distributed ledgers, blockchain 1.0, was marked by Bitcoin, the digital currency that challenged the fundamental aspect of monetary centralization. Since then, the industry has been growing at exponential rates as BTC has brought the digital gold narrative back to life with enthusiasts regarding it as the most decentralized form of a digital asset class.

As much as it is a good thing, Satoshi’s network has been seeing bottlenecks; to the point where Bitcoin transactions take close to 10 minutes because of the congestion in transaction volumes. This was a huge setback, as Bitcoin’s scalability problem has limited the rate at which the Bitcoin network manages to process transactions, sparking a race among startups who have embarked on the quest to solve the nascent digital currency scalability problem.

Apart from financial transactions, blockchain 2.0 with the creation of cryptocurrencies such as Ethereum went beyond the complexities of mere payment settlement; but instead leveraged the possibilities of programmable money and smart contracts.The most popular platform in this niche is Ethereum which was released back in 2013 and has since become the de facto platform for decentralized applications (DApps) and smart contracts.

The next wave was led by accelerated innovation that will likely strain one’s imagination when thinking about all the possibilities that DLT has to offer. With smart contracts that can be coded directly into a transaction, developers could further utilize the technology beyond its initial intended use-case. Despite being an advancement, blockchain 2.0 exhibited some shortcomings which are set to be addressed by the latest and next generation of distributed ledger protocols.

Blockchain 3.0 is said to be the future of DLT, and blockchains that fall under this category are optimized and designed from the ground up to overcome challenges faced by previous-generation blockchains. With emphasis on governance, enhancing privacy and security, interoperability, sustainability, and scalable ecosystems, blockchain 3.0 is set to be taking DLT development to the next level.

A number of projects have since popped up, including notable platforms like EOS, Cardano and Algorand which came into existence to address critical areas of focus: scalability, security and decentralization. Given the diverse priorities in feature specialization, a variety of models exist, but all the projects mentioned in this list will fit the criteria of a blockchain 3.0. This article further highlights and ranks the leading nine blockchain 3.0 platforms to watch out for in 2020.
