Upgrades on Upgrades - The Merge, Vasil hardfork, ATOM 2.0, and Kathmandu

PoS Round-Up is stakefish's focused biweekly report on the major news in and around the Proof of Stake ecosystem.

Welcome, fishfam and fellow crypto enthusiasts.

Despite the bear market, it has been an eventful few weeks in the cryptoverse - but then again, when isn't something happening?

The most notable event of the past few weeks are Ethereum's transition from Proof-of-Work to Proof-of-Stake, Cardano's Vasil hardfork going live, the announcement of the reimagined Cosmos Hub whitepaper, and Tezos's Kathmandu upgrade going live.

That's just a handful - there is plenty more.

Let's get into the updates in the PoS world.


Ethereum is now secured by Proof of Stake, switching off Proof of Work on September 15. The Merge went smoothly, noting only 1% drop in participation and 12-second blocks post-merge.

You have certainly seen The Merge panda meme floating around. Do you know the backstory?


The Solana foundation released its most recent Solana Energy Use Report as part of its commitment to making Solana carbon neutral.

Emissions per Solana validator fell nearly 48%, despite the network's estimated carbon footprint growing by 26%.

Primary drivers of emissions changes for Solana were:

  • Evaluating e-waste emissions for the first time (+1,639 tonne CO2/year)
  • A drop in estimated power use for validators (984W to 509W)
  • Better estimates of renewable energy use in data centers.


Robinhood’s Web3 Wallet beta is now live exclusively on Polygon.

Robinhood chooses Polygon as the first network to support in its new Web3 wallet. Robinhood wallet users will be able to trade and swap tokens, get crypto rewards, and connect to decentralized apps upon downloading the beta of the app - all with zero gas fees.

Polygon partners with Ankr AppChain Infra to provide tooling for building dedicated blockchains through Polygon Supernets to empower teams to build their own blockchains.

MATIC is now listed on the Binance card in Argentina. MATIC can now be used to make purchases at 90 million merchants in thousands of stores around the globe.


Cardano's Vasil hard fork went live on September 22. The hard fork is designed to improve the ecosystem’s scalability, general transaction throughput capacity, advance Cardano development capacity, and bolster the network’s current smart contracts to create a better experience for both users and developers.

The announcement was made by blockchain firm Input Output Hong Kong — whom oversees the design, building, and maintenance of the Cardano platform.
