The year 2025 has marked an acceleration in competition among decentralized ecosystems.

Key architectural trends include:

  • Modularity;
  • High performance;
  • Developer-first focus for native apps;
  • Strong user experience (UX).

In this article, we’ll take a look at 10 of the most popular and successful blockchain ecosystems leading the way this year.

Solana: Speed and Scalability

  • What is it?

A high-performance blockchain featuring a unique Proof of History consensus mechanism.

  • Who launched it and when?

Launched in March 2020 by the Solana Labs team, led by Anatoly Yakovenko.

  • Why is this project important?

Solana has become a hub for DePIN, DeFi, and NFT innovation. Thanks to its high throughput, it's well-suited for mass adoption — including micropayments and gaming.

It’s also one of the most active blockchain ecosystems in terms of employment, offering job opportunities to hundreds of developers building on Solana. 

  • What are the numbers?

2,000 validators, 100,000 TPS (transactions per second) in peak tests, 15 million active addresses on the network (as of May 2025).

Solana’s internal liquidity aggregator, Jupiter, has crossed the $15 billion mark in monthly trading volume.

Cosmos: The Internet of Blockchains

  • What is it?

An ecosystem of independent but interoperable blockchains.

  • Who launched it and when?

Launched in 2019 by the Tendermint team (now Ignite), led by Jae Kwang and Ethan Buckman.

  • Why is it important to the market?

The Cosmos SDK and IBC (Inter-Blockchain Communication) enable the creation of fully interoperable custom networks within a single ecosystem.

This reduces fragmentation and builds a unified crypto space. Cosmos is a widely used core for modular blockchain architecture.

  • What are the numbers?

Over 50 blockchains support IBC (as of May 2025).

The number of intra-ecosystem transactions has grown by 170%.

Active projects in the Cosmos ecosystem include: dYdX (migrated from Ethereum), Celestia, Osmosis, Sei.

Polkadot: Modularity and Parachains

  • What is it?

A blockchain with a parachain architecture for decentralized applications.

  • Who launched it and when?

The idea was introduced by Gavin Wood in 2016, and the main network launched in May 2020.

  • Why is it important to the market?

Parachains allow developers to launch blockchains with specialized logic under a shared validator set.

This lowers the barrier for launching custom networks and makes Polkadot a flexible solution for Web3 startups.

We remain optimistic about Polkadot’s technological direction — despite the platform receiving occasional, well-founded criticism.

  • What are the numbers?

30+ active parachains, over 500 projects in development.

In 2024, transaction volume grew by 140%, and the network treasury allocated $200 million to infrastructure support.

Sui: Scalability and UX

  • What is it?

A blockchain developed by former Diem engineers, featuring a unique object-based model.

  • Who launched it and when?

Launched in May 2023 by Mysten Labs, founded by former Meta (Facebook) developers.

  • Why is it important to the market?

Sui uses parallel transaction processing, which reduces confirmation times and improves the overall user experience.

It’s actively used in Web3 gaming and NFT applications.

  • What are the numbers?

Achieves up to 500,000 TPS in lab tests.

Processed over 20 million transactions in April 2025.

The ecosystem includes 150+ projects, including major game studios and NFT marketplaces.

Aptos: Diem Legacy and High Performance

  • What is it?

A high-performance blockchain built with the Move programming language by the team behind Diem. A key competitor to Sui in the decentralized application network space.

  • Who launched it and when?

Launched in October 2022 by Aptos Labs, a team of former Meta employees.

  • Why is it important to the market?

Aptos supports complex use cases and features sub-one-second transaction finality. It’s particularly effective for DeFi, gaming, and AI integrations.

  • What are the numbers?

Up to 160,000 TPS, over 7 million active wallets, and $1.2 billion TVL (as of May 2025).

The number of developers has grown by 90% over the past year.

Aptos supports several major decentralized platforms — including PancakeSwap

Berachain: An L1 Based on Proof-of-Liquidity

  • What is it?

A new Layer 1 blockchain that uses a Proof-of-Liquidity (PoL) consensus algorithm, built on the Cosmos SDK.

  • Who launched it and when?

After a long testnet phase (since 2023), the liquidity provisioning mechanism officially launched on March 24, 2025.

The project was founded by an anonymous team known as the “bears” from within the crypto enthusiast community.

  • Why is it important to the market?

It introduces the Proof-of-Liquidity model, where DeFi activity directly influences consensus participation.

This creates a synergy between validators and liquidity, aligning network security with financial utility.

  • What are the numbers?

Over 120,000 users in testnet, 15+ dApp projects.

Governance participation rate is above industry average — 65% active votes.

Celestia serves as the foundational infrastructure for launching other EVM-compatible networks.

  • Who launched it and when?

Mainnet launched in October 2023.

The project is developed by Celestia Labs, led by Mustafa Al-Bassam.

  • Why is it important to the market?

It offloads blockchain architecture by separating the data availability layer from the execution layer.

This enables the deployment of lightweight rollups, saving resources and reducing data processing time.

  • What are the numbers?

The number of rollup projects built on Celestia grew from 5 to 27 (from June 2024 to May 2025).

Network transaction load increased by 300% during the same period.
