When DeFi flourished in 2020, Ethereum was practically the only prominent L1 out there. In 2021, things changed. Many L1s developed to address the challenges associated with the Ethereum network and have caught significant traction. And in 2022, we’re continuing to see a lot of new L1s on the rise that can compete in this sector.

In 2020, Ethereum accounted for 95% of all DeFi liquidity. Today, Ethereum accounts for almost half of all DeFi liquidity - other L1s have captured liquidity from Ethereum.
With various chains, we believe that the future of DeFi will include multiple L1s, not just one, each with its niche.
This report acts as a culmination of facts after deep research into each and every L1 that has tried to exist since 2018, and why only a few were home runs. This will act as a base for the decision-making process going forward for the CPro Research team when it comes to choosing amongst the sea of L1s.
From there, we will collectively decide on a few chains we hone in on and create research reports about.

A Layer 1 (L1) or a smart contract platform is the underlying core architecture of blockchain technology. Developers build decentralised apps on top of Layer 1. Think of the Internet as an L1 and Instagram as one of the apps built on the internet.
An L1 processes and finalises transactions on its blockchain. L1s have their own native tokens, usually used to pay transaction fees.

L1s are the Base Layers within their ecosystems. The Application Layer is built on the L1 - think Synthetix (app) built on Ethereum (L1).
Ethereum was the first Layer 1 to implement smart contracts. Many other L1s have followed suit since. Some have been successful long-term, some were successful temporarily, and some failed.

Back in 2018, EOS a smart contract Layer 1 raised over $4bn in the largest Initial Coin Offering ever, but it couldn't compete with Ethereum. Cardano was vastly overhyped with little to no DeFi activity. Elrond allows developers to build a smart contract with the potential to earn 30% of the smart contract fees as royalties, yet there is only one protocol in its ecosystem. And Terra had the largest decentralized stablecoin ever (UST), and yet the entire chain eventually collapsed.
But what did the home runners have in common? What are the crucial elements needed for the success of a new L1?
After extensive deep research, we determined that an ideal Layer 1 should include the following features.
Security is assessed by :

Decentralisation is assessed by:
BNB Chain & EOS have a cap on the number of nodes - 21.[/caption]

Network activity is assessed by:

Gradually increasing over time: Ethereum, Solana, BNB Chain, Avalanche, Cardano, Elrond and Tezos. Gradually decreasing over time: EOS & Ontology.[/caption]
Or is the project attempting to become the next Ethereum? Is it claiming to solve issues that do not exist?
Ethereum pioneered smart contracts, Solana was the first blockchain with 400ms block time, Avalanche is highly scalable with near-instant finality, and BNB Chain, with BNB being the chain’s token backed by the world's largest exchange - Binance. Cardano, EOS, Elrond, Tezos, and Ontology tried but failed to solve Ethereum's scalability problem because their focus was on replicating Ethereum rather than bringing a new and valuable product.
Note:
Team, backers, investors and community are also important factors to tie in with the above, however, we chose to leave them out, and include them when covering assets in separate reports.
In terms of developer interest, Cardano is one of the top three L1s. Solana and Avalanche have fewer nodes than Tezos and Elrond. However, what distinguishes an L1 are its protocols. Users are constantly using these protocols in winning L1s - high revenue. The most important lesson we learned today is that if an L1 does not have widely used applications, it will have low revenue, which equals poor L1, regardless of how strong it is in other areas.
According to our framework, an ideal homerun Layer 1 would have high-security incentives derived from the model and rewards. Decentralised by having low barriers to participation in the network - neither too low nor too high. Massive developer interest, widely used applications, and high TVL and revenue.
Evaluating any Layer 1 is difficult, especially given the hundreds of smart contract platforms available today. However, we were able to develop our model to determine whether an L1 has a chance of making it or not. Smart contract platforms are now available for the Web3 generation of internet applications. But the question remains which L1s will have a chance of succeeding?
This infrastructure will support trillion-dollar companies, similar to Web2.
In the following report, we will go over CPro's top contenders in the L1 sector!
