Major Events on ETH, Polymarket & Circle on 28 Oct

Major Events on ETH, Polymarket & Circle on 28 October

Today in this segment, we look at the major events that took place in the crypto eco-system, specifically those related to Ethereum’s Fusaka upgrade, Polymarket’s U.S. comeback and Circle’s Arc blockchain testnet with heavyweight institutional backing.

In Major Event, Ethereum’s Fusaka Fork Shines on Final Testnet

One of the most anticipated major events in crypto unfolded Tuesday as Ethereum’s Fusaka upgrade went live on the Hoodi testnet. Fusaka upgrade is set to be launched on the mainnet on December 03, 2025. 

This milestone promises to supercharge the network with enhanced scalability and security, addressing key challenges in the blockchain trilemma of decentralization, security, and efficiency.

Fusaka integrates cutting-edge Ethereum Improvement Proposals (EIPs) to revolutionize performance. Additionally, EIP-7594, introduces Peer Data Availability Sampling (PeerDAS), allowing validators to process smaller data chunks from layer-2 networks instead of full blobs.

All this will dramatically boost efficiency while reducing operational costs. It will also pave the way for smoother layer-2 interactions.

Polymarket’s U.S. Relaunch: A Game-Changer on the Horizon?

Another headline-grabbing major event would be Polymarket reentering the U.S. market within weeks. 

That’s right! The decentralized prediction market platform has plans for a limited rollout by late November, initially focusing on sports betting to comply with regulatory frameworks, according to Bloomberg.

Now interestingly enough, this development comes after a no-action letter from the U.S. Commodity Futures Trading Commission (CFTC) to a crypto derivatives exchange acquired by Polymarket.  

CEO Shayne Coplan called the move a green light to “go live in the USA.” Polymarket’s website now teases a waitlist, promising U.S. traders imminent access. 

Circle Unveils Arc Testnet with Elite Institutional Alliance

Rounding out major events from yesterday is Circle. Circle, the issuer of the world’s second-largest stablecoin, USDC launched the public testnet for Arc.

Arc is a layer-1 blockchain dubbed the “Economic Operating System for the internet.” The debut attracted over 100 blue-chip participants, including BlackRock, Goldman Sachs, Visa, Mastercard, and State Street, signaling unprecedented institutional confidence.

Circle CEO Jeremy Allaire is delighted with the network’s early momentum, noting that participating firms collectively serve billions of users and manage trillions in assets and payments. 

In other developments, Japan’s Metplanet put on a big fight after Metaplanet shares slid amid wild market swings with the company’s mNAV ratio going below 1.0. This is despite Metaplanet being Asia’s Bitcoin-hoarding titan. News has it that the board made a 150 million share repurchase via the Tokyo Stock Exchange, to juice earnings per share, sparkle up market perception, and send Metaplanet shares soaring north. 

And that’s all the major events from yesterday friends. Keep watching this space for more updates and more major events and activity from the crypto eco-system.
