BlockDAG Beta Testnet Is the Ultimate Sandbox for Future Web3 Creators

Not all blockchains are built the same—and in 2025, the gap is widening. Projects like Mantle and Sui have focused on speed and scalability, offering modular design and parallel execution to push performance metrics. Mantle’s growth reflects rising developer interest in cost-efficient Layer 2 solutions, while Sui’s asset-centric programming continues to attract traction in gaming and DeFi.

Yet, while these platforms emphasize architecture, BlockDAG adds something tangible to the equation: a working testnet, real-world hardware, and hands-on tools for creators. With a $208 million presale and a live beta environment, BlockDAG positions itself not just as scalable—but as real.

Mantle: Modular Design for High-Performance Layer 2 Scaling

Mantle is a modular Ethereum Layer 2 network designed for high-throughput and low-cost transactions. It combines Optimistic Rollups with EigenDA, a decentralized data availability layer, to process transactions rapidly while remaining compatible with the Ethereum Virtual Machine (EVM).

It is a Layer 2 optimistic modular blockchain. Its architecture is split into three layers:

* Execution Layer: Processes transactions and maintains the network's state.

* Data Availability Layer: Stores transaction data in a decentralized manner.

* Consensus Layer: Secures the network and finalizes transactions.

Its aim is to integrate with Ethereum’s Beacon Chain in the long term. It is also an optimistic rollup, meaning that it assumes all transactions are valid unless proven otherwise. This allows for faster transaction speeds and lower fees.

The network is being developed by Mantle Labs, a company that is committed to building a sustainable and inclusive Web3 ecosystem. Mantle is fully aligned with the long-term vision of Ethereum and is being built to be a key component of the future of decentralized finance (DeFi).

Mantle (MNT) launched following the rebranding of BitDAO, which allocated tokens through a community-driven governance process. This in turn built trust among initial backers. Over time, MNT has grown steadily. As of March 29, 2025, Mantle trades at $1.22, up 53.8% from $0.79 in March 2024.

Furthermore, the network’s TVL has also grown to over $950 million, supported by growing dApp integrations and incentives for developers.

Overall, Mantle continues to be a Layer 2 solution with a focus on modular architecture, cost-effectiveness, and alignment with Ethereum’s long-term scaling roadmap.

Sui: Speed-Focused Layer 1 Built with Move Language

Sui is a Layer 1 blockchain designed by Mysten Labs, and it is powered by the Move programming language. It is designed for speed and scalability, with the ability to execute transactions in parallel and achieve sub-second finality. Sui also adopts a "single-program, multi-object" model, which allows for more efficient processing of transactions.

Sui is used to build a variety of dApps, including games, NFTs, and DeFi protocols. It is also being used to develop new types of dApps that are not yet possible on other blockchains.

In terms of early backers, Sui launched its token (SUI) through Binance Launchpool and direct sales in early 2023, ensuring wide distribution and early utility. As of March 29, 2025, SUI trades at $1.39, up 81% from $0.77 in March 2024. This growth reflects strong developer traction and increased user adoption across DeFi and gaming sectors.

Moreover, the protocol’s native support for asset-centric programming makes it ideal for building NFTs, wallets, and games with advanced logic. With increasing TVL and more than 1.2 million monthly active wallets, Sui has positioned itself as a fast, developer-first chain focused on user experience and real-world scalability.

Why BlockDAG’s Beta Testnet Is the Ultimate Sandbox for Future Web3 Creators

BlockDAG's recently launched Beta Testnet isn't just a technical milestone—it's a working playground for developers, token creators, and early adopters to build, test, and refine Web3 applications in real time.

With core infrastructure now twice as fast, a streamlined token and NFT creation wizard, and multiple decentralized applications already live, the testnet gives users a chance to experiment with real tools ahead of mainnet launch. It's not a simulation; it's the foundation of a Layer 1 chain that's already proving its potential.

Developers can already launch ERC-20, ERC-721, and ERC-1155 tokens without needing to write code, and builders can interact with a WASM-compatible environment that supports smart contracts
