Hey there, crypto enthusiasts! If you’ve been scrolling through X lately, you might have stumbled upon a thought-provoking thread from Sacha Saint-Léger, posted on July 12, 2025. This blockchain aficionado dropped four bold convictions that are sparking debates across the crypto community. As someone who’s spent years diving into the world of digital currencies—previously as editor-in-chief at CoinDesk and now at Meme Insider—I’m excited to break this down for you in a way that’s easy to digest, especially if you’re into meme tokens or just curious about the latest blockchain tech.

What’s Sacha Saying?

Sacha’s thread is a call to action, ending with a cheeky “come @ me 🦣” invite for discussion. Here are the four predictions that have everyone talking:

1. Base Layer MEV Is Heading to Zero (or Close)​
   MEV, or Miner Extractable Value, is the profit miners or validators can make by reordering or including transactions. Sacha believes this will drop to almost nothing. Why? Some argue it’s because of evolving mechanisms that reduce arbitrage opportunities, though skeptics like Lachlan Breakey point out that arbitrage will always exist, especially with high-frequency trading firms like Citadel in the mix.

2. Proof-of-Stake (PoS) as We Know It Will Become Obsolete
   PoS is the consensus mechanism used by networks like Ethereum, where validators stake crypto to secure the network. Sacha suggests this might fade out, possibly hinting at newer systems like delegated proof-of-stake (DPoS) or even something entirely different. This has raised eyebrows—5dayoldburrito asked about contentious state/priority fees as an alternative, showing the debate is far from settled.

3. Demand for Credibly Neutral Blob Space Will Skyrocket 10,000x
   This is the head-scratcher! “Blob space” refers to data storage in blockchain rollups, and “credibly neutral” means it’s free from centralized control. Sacha predicts a massive surge in demand, likely tied to scalability solutions. This ties into projects like Celestia, as Faizan09 hinted. It’s a big claim, and the community is buzzing about how this could reshape layer 1 networks.

4. Data Availability (DA) Is the Only Sustainable L1 Revenue Source
   Data availability layers ensure all transaction data is accessible, crucial for rollups. Sacha argues this will be the long-term money-maker for layer 1 blockchains, contrasting with bad_cosmonaut’s view that transaction fees (like Bitcoin’s) will always cost something. This prediction aligns with innovations like EigenDA and Avail, which are pushing DA forward.

Why It Matters

These predictions could shake up the blockchain world, especially for those of us tracking meme tokens and their underlying tech. If MEV drops and PoS evolves, it might affect how tokens are mined or staked, potentially impacting projects on Ethereum or other layer 1s. The 10,000x demand for blob space could mean new opportunities for scalable meme token ecosystems, while DA revenue might shift how developers fund their networks.

The Community’s Take

The thread blew up with reactions. cola humorously clicked the like button four times, attaching a meme of a relaxed guy in a suit—perfect for the laid-back yet bold vibe. Others, like Bitvizory, called the blob space prediction a “significant shift,” while Joe Dirtay admitted it’s a “head-scratcher.” The debate’s alive, with challenges to every point, making it a hot topic at Meme Insider.

What’s Next?

It’s 03:25 AM JST on July 15, 2025, as I write this, and the conversation is still fresh. Sacha’s thrown down the gauntlet—will MEV vanish? Will PoS fade? Can blob space demand really explode?
