Kaspa and SEI are two blockchains that parade themselves as being very fast. The community also sees their speeds as selling points; but which one is really faster between the two? That is the focus of this article, taking reference from a video by Marius on his YouTube channel 10X by Marius.
In the video titled “Casper vs SEI. Who is faster? The ultimate speed comparison,” Marius breaks down the strengths and trade-offs of both Kaspa and SEI based on their architecture, tokenomics, scalability, and long-term goals. While both projects push the speed narrative, they go about it in different ways. One is proof of work and the other is proof of stake. This makes a direct comparison difficult, but not impossible.

Kaspa vs SEI: Speed, Architecture, and Use Case
Marius starts by explaining how Kaspa operates using a blockDAG model. Unlike traditional blockchains like Bitcoin that process one block at a time, Kaspa can process multiple blocks simultaneously. This makes it much more efficient. Kaspa is built on a proof-of-work foundation, meaning it offers strong security while also preparing for scalability with upcoming smart contracts. Because of this, many people in the crypto space call Kaspa “Bitcoin 2.0.”
SEI, on the other hand, follows a totally different path. It’s a Layer 1 blockchain built on the Cosmos SDK, optimized for decentralized finance and high-speed trading. SEI is a parallelized EVM, and its structure is focused on handling transactions and orders at lightning speed. It offers instant finality, low latency, and high scalability, which are all great for traders and apps running on decentralized exchanges or NFT marketplaces.
While both Kaspa and SEI process blocks simultaneously, their goals are quite different. Kaspa is more about technical strength and infrastructure, while SEI is aiming to dominate the fast-growing DeFi and trading markets.
KAS Price, SEI Tokenomics, and Circulation Strength
Marius also dives deep into the market stats and token distribution of both Kaspa and Sei Network. Kaspa currently has a market cap of about $2.62 billion, with roughly 92% of its tokens already in circulation. This shows strong decentralization and a fair distribution, especially since there was no pre-mine or investor vesting involved.
Sei Network’s market cap sits sl
ightly lower at $2.12 billion, with only 75% of tokens in circulation. A significant portion of SEI tokens is still locked, mostly allocated to the team, investors, and the foundation. This means more tokens could enter the market in the future, potentially adding to selling pressure.
On the emission side, Kaspa follows a predictable structure where mining rewards are halved each year. It doesn’t support staking since it uses proof of work. SEI does offer staking rewards of around 3% to 5% annually, but these rewards come from reserves and could create future supply pressure. Marius believes Kaspa holds an edge here with its deflationary nature, while SEI offers more immediate incentives but with higher risks.
Community Momentum and Long-Term Potential
Both projects have passionate communities, but the style of growth is different. SEI has recently seen fast adoption, with over 500,000 wallets created. This reflects momentum driven by DeFi narratives and trading use cases. Kaspa, in contrast, has grown organically and steadily over time. Its fair launch and lack of early whales mean fewer chances of large-scale dumps or volatility.
From a vision standpoint, Kaspa is all about long-term infrastructure. It stays mostly quiet in the media space but continues to build and improve its tech. SEI is much more media-friendly and is riding high on the buzz surrounding decentralized finance, with strong backers and active ecosystem growth.

Marius wraps up by saying that both projects are exciting, but they represent different ideas. SEI is high-speed and high-risk while Kaspa is solid, technical, and built for the long run. Choosing between them comes down to what users or investors value more: the fast, hype-driven growth of SEI or the consistent and fair architecture of Kaspa.
Both Kaspa and SEI are strong in their own right. But when it comes to raw speed, the comparison is not just about numbers but about purpose, technology, and how each blockchain fits into the future of crypto.
