Sei Labs

The blockchains of tomorrow need to be designed for fast finality, high throughput, and quantum resistance. That's what Sei Labs is building for with the Giga Upgrade. Sei Labs Co-founder, @jayendra_jog, onstage at ETH CC, for the IYKYK series.

Making today's blockchains quantum secure is a challenging task. For next-generation, ultra high throughput blockchains like Giga, the problem is exponentially worse. In their latest piece, the Sei Research Initiative explores the implications of making Giga quantum secure. The naive solution would be to simply introduce a quantum secure signature scheme to Sei Giga. However at Giga's level of throughput, the bandwidth required for signatures would explode from 13 MB/s to at least 1.57 GB/s.

Check your Sei wallet: if you hold USDC.n (USDC via Noble), you should move to native USDC before the end of March 2026. The SIP-3 upgrade (expected on mainnet in late March) will effectively make Sei an EVM-only chain, and Cosmos-native assets like USDC.n won’t be supported. For holders of smaller amounts, use DragonSwap or Symphony to swap USDC.n → USDC with little to no slippage. www.dragonswap.app www.symph.ag For holders of large amounts, you can use this batch migration tool to convert USDC.n → native USDC on Sei Network. It routes Noble → Polygon → back to Sei Network via Circle CCTP. https://lnkd.in/etgfCbqM If your USDC.n is supplied on DeFi protocols such as Yei or Takara Lend, you should wind down and close positions → withdraw USDC.n → then swap or migrate before the SIP-3 upgrade deadline. https://lnkd.in/ePv47Ad4 https://app.yei.finance/ More here: https://lnkd.in/ejQZ-ttW For further questions, join the Sei Network Discord: https://lnkd.in/e2Y5HsJh

Some photos from the Sei Labs offsite in New York. The team has never been this big and this ready to build. Huge progress made.

In distributed systems, consensus protocols ensure safety between unknown third parties. But no technology emerges full formed. In a new Sei Labs research post, we sketch a map of how consensus has evolved over the last 20 years. Here's what it showed: Early chains bundled ordering, execution, and state into one slow loop. The newer designs we study peel this apart: consensus becomes a high‐speed ordering + data layer, and execution runs asynchronously and in parallel. That’s the core idea behind Sei Giga. The period with arguably the most innovation overlaps with the arms race to solve the blockchain trilemma by decoupling data dissemination, ordering, and execution. This generation saw the rise of protocols spearheaded by Sui and Aptos's Narwhal, and the Dumbo family. At the frontier of consensus protocols are Giga and Solana's Alpenglow upgrade, developed by @TheWattenhofer and the team at @Anza_xyz. Sei Giga will provide an unprecedented combination of optimal best case and low worst case latency, critical for reliable systems. Giga and Alpenglow approach the holy grail of the trilemma properties using fundamentally different paradigms: single-leader and multiple concurrent proposer, with extremely distinct challenges and benefits.

Recently wrote an op-ed piece for Cointelegraph: Scaling the EVM requires an L1, not an L2 L2s come with their own set of challenges—centralization risks, fragmented liquidity, and complex UX. The real answer to scaling the EVM is going back to first principles and reimagining L1s with high performance at the core. Read the full piece: https://lnkd.in/g8dhe5Ff
