In this article, we spotlight five promising blockchain startups founded in the past five years – each offering unique solutions that could redefine the way we interact with decentralised networks in 2025 and beyond.
1. Aptos
Sector: Layer-1 Blockchain
Founded: 2021
Overview: Aptos is a next-gen layer-1 blockchain designed to bring scalability, security, and decentralisation to the blockchain space with its innovative Move programming language. It aims to provide faster transaction speeds, higher throughput, and a better developer experience compared to older blockchains.
The company was founded by Avery Ching and Mo Shaikh with a simple but ambitious goal in mind: to create a resilient and scalable foundation capable of creating fair and efficient products for the future.
Shaikh, who has since stepped down as CEO but remains a strategic advisor, says he is incredibly proud of how far the business has come. “Aptos stands as one of the most robust ecosystems, trusted by over a thousand builders and innovators around the globe,” he explains. “The ecosystem has thrived across cycles, growing stronger and more vibrant each time.
“One of my true passions lies in building companies from the ground up and we have done that at Aptos Labs by building a world-class team.”
He believes that the talent and drive of Aptos Labs will bring their collective vision to life, with Ching having stepped in as the Aptos Lab’s CEO to drive the company into its next phase of growth.
Shaikh adds: “The Aptos ecosystem continues to shine, driven by the incredible work of early builders.”
None of it would have been possible without the unwavering support of their investors, he notes.
“Raising $400M was an incredible feat, and this strong foundation has been instrumental in enabling Aptos to thrive and grow.
“The team at Aptos Labs is world-class. They have worked tirelessly to craft this ecosystem from scratch. Technology without them is technology without soul. Their care and efforts are the reason we stand with confidence today, and their work will only accelerate as Aptos enters its next chapter.”
I will always remain a champion of Aptos and its mission. As such, I will stay on as a strategic advisor to Aptos Labs and look forward to continuing to help Aptos maintain its role as the world’s leading blockchain.
Over the coming months, I plan to take some much-needed time to reflect on where the world is headed and to think deeply about the ways financial systems can evolve to continue to push Aptos as the most established layer 1 in the space.
Why Watch: With its high-speed transactions and potential to scale efficiently, Aptos could rival the likes of Ethereum and Solana in 2025, especially in the areas of decentralised applications (dApps) and decentralised finance (DeFi).
2. LayerZero
Sector: Cross-chain Interoperability
Founded: 2020
Overview: LayerZero is a blockchain protocol designed to enable seamless cross-chain communication. By providing decentralised interoperability, it allows applications to operate across multiple blockchains effortlessly, solving the problem of siloed ecosystems.
In 2022, the company raised $135m in funding, with investors including Coinbase Ventures, PayPal Ventures, Tiger Global and Uniswap Labs. The funding round valued LayerZero Labs at $1bn and was intended to accelerate the development of cross-chain decentralised applications (dApps) powered by LayerZero, a decentralised omnichain interoperability protocol.
At the time, Bryan Pellegrino, CEO and co-founder of LayerZero Labs, described the funding round as a massive step forward for the company and the unfolding interoperability landscape.
He says: “We’ve brought some of the best and most well respected entities in the world together to accomplish the same goal: create the generic messaging layer that underpins all interoperability between blockchains.”
Why Watch: As the need for cross-chain communication grows, LayerZero’s solutions could unlock new opportunities for multi-chain decentralised applications and DeFi protocols.
3. Concordium
Sector: Privacy & Compliance
Founded: 2020
Overview: Concordium is a layer-1 blockchain that focuses on creating a compliant, secure, and scalable platform with privacy features. It offers a unique approach to privacy, combining transaction confidentiality with identity management to ensure compliance with regulatory standards.
Speaking to FinTech Magazine, Lars Seier Christensen, co-founder & chairman of Concordium, says: “I’m proud of what we are building at Concordium and that our idea of finding common ground between the power of decentralised systems and the world that exists around us is gaining ground.
“People now increasingly understand that this will be a merger between two worlds more than a replacement, and that both worlds can contribute to a more efficient future economy.”
Boris Bohrer-Bilowitzki, the company’s CEO, says: “Data privacy is one of the biggest concerns for the next generation, and Concordium will continue to develop, implement, and secure new technologies that ensure the digital safety of global citizens.
“The days of the crypto wild west are over, and we are ready to embrace regulatory challenges with class-leading identity verification solutions.”
Why Watch: Concordium is positioning itself as the blockchain of choice for institutions, especially in highly regulated industries. As privacy and compliance become more critical, it has the potential to become a major player in the enterprise blockchain space.
4. Flare Networks
Sector: Blockchain Interoperability & Smart Contracts
Founded: 2020
Overview: Flare Networks is a layer-1 blockchain built to bring smart contract functionality to blockchains that don’t natively support them. By enabling the integration of non-Turing complete blockchains (like Bitcoin) with smart contracts, Flare facilitates interoperability across multiple chains. Its native Flare Token (FLR ($0.01)) is used for governance, staking, and securing the network.
Explaining his move from the finance sector into the world of blockchain, Hugo Philion, co-founder and CEO of Flare Networks, says: “I just thought I wasn’t doing anything that was interesting or valuable in life.”
Now, the reason for Flare networks existing is data, he told Crypto Potato. “And there’s no one else really doing a layer one for data. Then, if you add in our relay protocols, it’s not just data. It’s also really quite nice interoperability because we can build bridges and we can do general message passing, and we can also provide our data as an Oracle service, as a properly decentralised Oracle service to any network. So we kind of don’t see ourselves as an L1. We see ourselves as a utility to a patchwork of different blockchains.”
Why Watch: Flare’s ability to provide smart contract capabilities to networks like Bitcoin, XRP ($2.32), and others, gives it a significant advantage in enhancing the interoperability of different blockchain ecosystems. As multi-chain ecosystems and interoperability become more critical in blockchain’s future, Flare’s potential to connect various decentralised platforms positions it as a major player in the coming years.
5. Celestia
Sector: Modular Blockchain Architecture
Founded: 2020
Overview: Celestia is a modular blockchain designed to decouple consensus and execution, enabling more scalability and flexibility. By allowing different execution layers to operate independently, Celestia aims to improve performance and reduce the complexity typically associated with traditional blockchains.
Celestia Mainnet Beta went live in October 2023, delivering the industry’s first specialised modular consensus and data network. Since launch, an early ecosystem has taken form, with developers deploying the first 20 rollup chains and Celestia data blobs recently hitting more than half of total data published by rollups.
A spokesperson for Celestia says its launch is an opportunity for ambitious developers to push the envelope. “The modular stack invites developers to create novel applications unlocked by abundant blobspace, like onchain gaming,” they add.
Later, in September 2024, the company raised $100m in support led by Bain Capital Crypto, with participation from Syncracy Capital, 1kx, Robot Ventures, Placeholder and others. This brought the project’s total amount raised to $155m.
“When Celestia launched as the first modular data availability layer, it scaled blockspace from the dial-up era to the broadband era,” says Mustafa Al-Bassam, co-founder of Celestia and Chairman of the Celestia Foundation. “Now, the core developers have introduced the technical roadmap to scale blockspace to the fibre optic era – while keeping it verifiable and low latency.”
Why Watch: Celestia’s unique approach could pave the way for more customisable and scalable blockchain solutions, especially for developers looking for high flexibility and performance.
