The hottest Blockchain Substack posts right now

Season 4 is live with lots of new content and ways to play. There’s a 1.66M POWER prize pool and new features like premium events, raids, ability tomes, and 140 PvE campaign levels.
Guilds launch December 8 so you can create or join a group to defend kingdoms, raid others, earn Guild Valor and Guild Glory, and compete in Guild Wars; each guild can have up to fifty members.
To get started, download the game on iOS or Android, follow the tutorials, and read the litepaper; players can also buy and stake a Kingdom NFT (around 150 RON on Ronin Market) to unlock extra opportunities, and new hero Ember offers a high-risk, high-reward playstyle.

The game now has xFISH (a spend-only, non-tradeable reward token) and on-chain $FISH, and players can stake tokens or convert xFISH to $FISH with fees that vary based on Karma.
Chapter 2 adds new areas like the Cavern Permanent Zone (unlock at Fishing Level 80) plus Event and Permanent Zones, and introduces Fossils you collect to unlock new fish with set rarity chances and a Mythic pity at the 300th fossil.
Karma is a central reputation score that boosts rewards, unlocks daily quests, leaderboards, and better conversion fees, and you earn it by playing, referrals, quests, staking tokens, or buying a Founder’s Pass—so claim and stake any $FISH airdrop to increase it.

Season 13 of Axie Classic is live from Jan 22 to Feb 22, and players can compete for over 36,000 AXS across guild leaderboards, arena leaderboards, season champion prizes, guild milestones, and daily mini tournaments.
The Free Battle Pass is back, letting players earn free gold, artifact copies, and up to 4,000 Dust just by playing.
Competitive Circuit 2 now spans four seasons (S13–S16), removes the Guild Wars format, and lifts most previous bans except Maxcy/JDY; it will culminate in an 8-player Classic Champions Invitational with a 5,000 AXS prize pool.

Ethereum’s activity rose sharply after the Fusaka upgrade, with daily transactions up about 50% and active addresses up roughly 60%, but a notable portion of that growth comes from address‑poisoning dust rather than organic usage.
Analysis of USDC and USDT balance updates shows many transfers are tiny dust amounts—about 43% under $1 and 38% under $0.01—often sent by a small number of accounts to millions of wallets.
Dust seeding now explains roughly 10–15% of transactions and 25–35% of active addresses on a typical day. Using adjusted metrics and wallet UI changes can help highlight real economic activity and reduce user risk.

The RSGP presale starts March 2nd on Ethereum and runs through March 4th; join by connecting your wallet to Cambria’s presale portal and depositing USDC or supported tokens, with allocations based on onchain history, Ethos score, and deposit share.
RSGP is meant to power features like staking benefits (for example reduced withdrawal fees) and governance over some game features. You won’t need RSGP just to play the games.
Cambria is a popular onchain MMO (Gold Rush and Duel Arena) with substantial onchain volume and peak players, and RSGP aims to help transition the game toward a persistent, always-online world.

Transactions can be intercepted and reordered by searchers and builders before they are confirmed, creating MEV opportunities like sandwich attacks that can hurt regular users.
Block builders gather public and private transaction flow and bid in a proposer-builder auction, so how they order transactions directly determines how much value they can capture.
These incentives favor a few dominant builders and raise centralization and censorship risks, and common mitigations include private transaction submission, skipping the public mempool, and moving activity to Layer-2s.
