Ethereum's New Shield Against Transaction Exploitation: What EIP-8105 Actually Does
Your transaction sits in a waiting room before it gets processed. Right now, everyone can see it. And that's a problem.
When you send cryptocurrency, your transaction doesn't instantly disappear into the blockchain. It lingers in what's called the mempool—a kind of digital holding area. Here's where things get ugly: miners and other sophisticated players can peek at what you're about to do, then rush their own transactions in front of yours to profit from the price movement. This is called MEV, or maximal extractable value, and it's costing everyday traders millions.
CoinTelegraph reported that a new proposal called EIP-8105 wants to change this fundamentally.
What makes this different from other EIP examples we've seen?
Well, most Ethereum Improvement Proposals (an EIP definition worth understanding: it's basically a formal suggestion to upgrade Ethereum's protocol) address specific bugs or add features. EIP-8105 is attacking the fairness problem itself. The proposal suggests hiding transaction payloads—the actual details of what you're trying to do—until after your transaction gets included in a block. Think of it like sending a sealed envelope instead of a postcard.
This matters because MEV isn't some obscure technical issue.
When you swap tokens, buy an NFT, or move money around, someone in the background is potentially watching and profiting from your moves. The encrypted mempool design would eliminate that surveillance opportunity. Your transaction details stay encrypted until the moment they're permanently recorded on the blockchain. By then, the damage is done—or rather, no damage can be done anymore.
So why does this matter to you? Because MEV extraction makes every transaction slightly more expensive and slightly less fair.
The real question is whether Ethereum can actually implement this without breaking other things. Security vulnerabilities don't announce themselves politely. When EIP-7702 (a previous proposal) was scrutinized, researchers discovered concerning vulnerabilities that required fixes. The eth vulnerability landscape is complex. Any major change to how transactions work carries risk.
And here's what separates this from the bitcoin vs ethereum which is better debate.
Bitcoin's network structure makes this particular problem less severe, which is one reason some traders prefer it. But Ethereum's flexibility—the reason it powers DeFi, NFTs, and complex smart contracts—creates these MEV opportunities in the first place. You're making a tradeoff: more functionality or more privacy. EIP-8105 is trying to have both.
EIP cyber security standards require extensive peer review before implementation. This isn't something the Ethereum developers will rush. Multiple research teams will scrutinize every angle. They'll ask: Does this actually hide transactions? Can it be broken? What's the performance cost?
The proposal means Ethereum's entire mempool architecture would shift. Instead of broadcasting transactions in the clear, nodes would handle encrypted data. Validators would decrypt and execute transactions only after they're committed. The technical complexity is substantial.
But here's the genuine upside: if it works, ethereum losing value to MEV extraction becomes less of a concern for regular users.
What can you do right now? If you're serious about DeFi trading or large transactions, pay attention to this proposal's progress. Services already exist that route transactions through encrypted channels (like MEV-protection services), and they're becoming more mainstream. When EIP-8105 advances, it'll likely mean these protections become native to the protocol.
The timeline matters. Protocol changes take months of testing. Don't expect this tomorrow. But watch for it in upcoming Ethereum developer calls and research discussions. This is the kind of infrastructure upgrade that shapes whether blockchain actually becomes fair for everyone or remains a game where insiders win.
