Scaling blockchains isn't optional anymore, it's survival.

Ethereum went the L2 route. Avalanche chose Subnets.

Both work, but they’re very different under the hood.

Now, let’s compare 🔺👇

🔸 X. 𝐀𝐫𝐜𝐡𝐢𝐭𝐞𝐜𝐭𝐮𝐫𝐞
⇛ Ethereum L2s (like Arbitrum, Optimism):
Built on top of Ethereum. They bundle transactions off-chain and post back to Ethereum for finality.

⇛ 𝐀𝐯𝐚𝐥𝐚𝐧𝐜𝐡𝐞 𝐒𝐮𝐛𝐧𝐞𝐭𝐬:
Built alongside the primary network. Each Subnet is its own blockchain with dedicated validators, rules, and even tokens.

🔸 X. 𝐂𝐮𝐬𝐭𝐨𝐦𝐢𝐳𝐚𝐭𝐢𝐨𝐧
⇛ L2s inherit Ethereum rules and limitations
⇛ Subnets are customizable: gas tokens, execution logic, permissions, compliance, and more

Subnets = full sovereignty
L2s = shared security

🔸 X. 𝐒𝐞𝐜𝐮𝐫𝐢𝐭𝐲 𝐌𝐨𝐝𝐞𝐥
⇛ Ethereum L2s settle back to Ethereum’s base layer
⇛ Subnets can share Avalanche security or build their own validator sets

More flexibility, more design space.

🔸 X. 𝐔𝐬𝐞𝐫 𝐄𝐱𝐩𝐞𝐫𝐢𝐞𝐧𝐜𝐞
⇛ L2s often require bridging, separate wallets, different RPCs
⇛ Subnets can feel like native Avalanche, fast, clean, integrated

Less friction = better onboarding

🔸 X. 𝐔𝐬𝐞 𝐂𝐚𝐬𝐞𝐬
⇛ L2s = general purpose dApp scaling
⇛ Subnets = app-specific chains, institutions, compliance zones, gaming environments

DeFi Kingdoms, Shrapnel, and Deloitte are all Subnet examples, tailor-made.

💡 𝐓𝐋;𝐃𝐑:
Ethereum L2s scale Ethereum.
Avalanche Subnets scale the idea of blockchains themselves.

L2s are extensions. Subnets are full ecosystems.

Both are powerful, but Avalanche is playing a different game. 🔺
