Today at dawn, smart contract security auditing firm ChainSecurity posted a Medium tweet revealing a critical security vulnerability in Ethereum Improvement Proposal (EIP) 1283. Originally a highly anticipated upgrade in this fork, EIP 1283 aimed to reduce gas fees, lowering costs for developers and users. However, the reduced gas fees introduced an unintended side effect: attackers could exploit the code to steal user funds.
Consequently, Ethereum developers postponed the fork indefinitely until the漏洞 is resolved. They plan to conduct additional code reviews, with the new fork date likely announced by Friday.
This last-minute vulnerability further dampened market sentiment, causing ETH prices to plummet by 4:30 AM:
For those unfamiliar with the Constantinople fork, here’s a quick primer:
Key Points About the Constantinople Fork
Q1: What’s the Purpose of This Fork?
Ethereum’s development unfolds across four phases:
- Frontier
- Homestead
- Metropolis (current phase)
- Serenity
Constantinople marks the final step of Metropolis, transitioning Ethereum from Proof-of-Work (PoW) to Proof-of-Stake (PoS).
Q2: Will a New Coin Emerge?
No. Unlike Bitcoin Cash (BCH), which resulted from a contentious hard fork, this upgrade enjoys broad community consensus. There will be no new coin—just an updated Ethereum blockchain.

Three Looming Risks
1. The Difficulty Bomb
Embedded in Ethereum’s code, the difficulty bomb escalates mining难度 exponentially, pushing block times beyond 15 seconds. By April or May, block times could reach 30 seconds, nearing a "冰河期" where mining becomes impractical. With the fork delayed, developers face a tight timeline—resolution must occur within months.
2. Eroding Future Expectations
If EIP 1283’s issues aren’t resolved promptly, developers might scrap it, deferring gas reductions to future forks. Undiscovered vulnerabilities could further undermine confidence, impacting ETH’s price.
3. Developer Accountability Concerns
This isn’t Constantinople’s first delay. Initially slated for November 2018, bugs postponed it to January 2019. Core developer Péter Szilágyi acknowledged:
"We can keep postponing upgrades."
Such unpredictability fuels skepticism about execution capabilities.
Ethereum’s Precarious Position
ETH’s value has plummeted from its peak, now trailing XRP in market cap. Competing公链 are luring away DApps, leaving PoS transition as Ethereum’s last stand. For believers, this dip may present a buying opportunity—assuming the upgrade succeeds.

FAQ
Q: Why was EIP 1283 controversial?
A: Its gas-fee reduction unintentionally enabled exploits, forcing a reassessment.
Q: How does the difficulty bomb work?
A: It algorithmically increases mining难度, eventually halting block production unless mitigated.
Q: Should I invest in ETH now?
A: While超跌, its post-upgrade potential hinges on resolving current crises. Proceed with caution.
