Learn how modular Layer-2 blockchains are helping developers build secure dApps for the Web3 future

Published at: Jan. 10, 2023

Arguably the most popular blockchain amongst developers building decentralized applications (dApps), the Ethereum Network is credited with introducing the Web3 community to innovations like smart contracts while maintaining robust security standards.

However, in order to solve Ethereum’s scalability issue, a new type of Layer-2 (L2) blockchain was introduced that relies on the Ethereum Mainnet (Layer-1) for its security but processes transactions on separate third-party networks in order to increase throughput speeds.

EVM compatibility for higher transaction speeds

Importantly,  developers had to ensure that these L2 blockchains were compatible with the Ethereum Virtual Machine (EVM), a run-time environment where Ethereum’s application code and smart contracts are executed, EVM compatibility ensures that smart contracts can be executed in a cross-chain environment, enabling Web3 developers to build dApps that can interact seamlessly with each other.

As a result, a number of decentralized finance (DeFi), gaming, and social dApps are built and hosted on L2 blockchains, marking a decided shift in Web3 developers’ preferences away from the Ethereum mainnet.

Eventually, L2 blockchains started innovating with new solutions and technologies that could reduce transaction fees or gas and ramp up the network’s speed to cater to a wider audience.  However, L2 blockchains have found it difficult to achieve hyper-scale without compromising on security standards because of the bridges or sidechains they employ. Therefore, in order to achieve both hyper-scale performance and Ethereum’s unparalleled security, a new kind of modular L2 blockchain had to be envisaged to provide a future-proof building platform for Web3 innovators.

Next-gen Layer 2 solutions

Introducing Mantle - a high-performance Ethereum Layer-2 network that leverages a separate decentralized data availability layer and combines it with Ethereum roll-ups to open up even more use cases for developers building on the Mantle ecosystem.

By separating execution, data availability, and transaction finality into separate layers, Mantle offers Ethereum-level security while increasing transaction speeds through reduced inefficiencies. In fact, transaction-related data is solidified on Mantle’s L2 before being broadcasted onto Ethereum, effectively trimming the challenge period and providing faster finality to the end user. In this way, Mantle is able to effectively utilize Ethereum’s massive trust network while eliminating possible blockspace congestion through its modular design.

As a result of these improvements, game developers can now build more elements on-chain without worrying about high transaction fees or struggling with poor end-user experience. Even advanced DeFi protocols that provide margin trading and other complex DeFi strategies can be developed and operated at a low cost, paving the way for much wider user adoption.

A product of BitDAO, Mantle is one example of how L2 blockchains can make Web3 technology more accessible. Moreover, the project shows how a blockchain built by a community-owned DAO can leverage member feedback and crowdsourced decision-making to constantly upgrade.

As more users and developers gravitate towards platforms like Mantle, the future of Web3 will focus more on modular L2 blockchains that can offer Ethereum’s trust while delivering lightning-fast speeds.

Universal Passport gives devs and users access to multiple blockchains
A public blockchain ecosystem has unveiled a Universal Passport that it believes will solve one of the industry’s biggest challenges: interoperability. Nervos says that its technology is compatible with existing standards, meaning that users who want to move assets from one network to another — or use apps based on different blockchains — will no longer need to contend with multiple interfaces and multiple identities. The company’s co-founder, Kevin Wang, told Cointelegraph: “We want to meet users where they are instead of asking them to get used to the interfaces that fit into the underlying plumbing or infrastructure.” Key elements …

DeFi boom drives 1,200% increase in DApp volume in 2020: Report
DApp transaction volume has topped $270 billion so far in 2020, with 95% of this figure belonging to Ethereum’s DeFi ecosystem, according to DappRadar. That’s an astonishing 1178% increase from last year’s total of $21 billion. The blockchain data provider revealed the figures in its annual DApp Industry Report today, summarizing the highlights and failures of a record-breaking year for DApp-based economics. The report noted that money has been flowing from BTC to ETH throughout the year, resulting in a rise in the price of ETH, from 0.018 BTC on Jan 1. 2020 to its current price of 0.028 BTC. …

Building multichain is a new necessity for DeFi products
At present, your DeFi product needs to be multichain to be competitive — this is the hard (and exciting) truth of 2021. Whether you’re building a wallet, a lending service or a DeFi game, your target audience knows that there is more to the crypto space than Ethereum. And they expect you to provide the best of all worlds. It seems there will always be a debate about which blockchain makes for the best foundation for projects. Enhanced security, low transaction costs and formidable speed — there will always be a chain that offers bigger advantages. As the speculators argue …

Ethereum price finally topped $3K, but data suggests a reversal is nowhere in sight
There is an old saying in traditional markets which is actually more like a trading rule. It goes, “when the trend is negative, one can only be neutral or short,” meaning bet on the price decrease. The problem is that a relief bounce tricks traders into believing that the negative prevailing sentiment has shifted into a buyers’ market. For example, after analyzing Ether's (ETH) price chart, one might conclude that after a 41% crash, a bull run should be ignited sooner rather than later. Unfortunately, this is a bit of a fallacy because markets can exist in periods of non-definition …
