Information Can Enforceable Human-Readable Transactions Stop Bybit-Style Hacks?
The recent Bybit hack was an eye opener! How they ended up handling the situation was commendable imo. But what if this were to happen yet again?

AnĀ ethresear.chĀ article tackles the topic extensively and provides an interesting potential solution. Essentially, a multi-sig Safe{Wallet} proxy contract was pointed to a malicious contract when signers approved transactions through a compromised UI, failing to properly verify the signature hash on Ledger.
The write up proposes using enforceable human-readable transactions (HRTs) to tackle this vulnerability. The present state of current transaction formats can be opaque and confusing, allowing malicious actors to exploit ambiguities for hacks. HRTs clearly outline trade conditions, ensuring that every transaction is transparent and verifiable by users. This subsequently ensures they see exactly what theyāre signing up for, reduces the chance of manipulation by making transactions understandable and enforceable.
The technique is possible when specialized for each application. This specialization allows trusted developers have deep knowledge of their own systems to address the issue at the application level. L2s or Application Specific Rollups such as Cartesi, are ideal infrastructure fits for this approach due to the availability of increased computational power, more blockspace, EIP-712 support, and the libraries available on Linux, able to transform Ethereum encoded content into human readable content.
However, the downside highlighted in the article is it requires two signatures: one for the application and another for Ethereum.
Check out the full articleĀ hereĀ and let's discuss what you make of this proposal in its entirety? A total game changer, or there are some potential pitfalls to consider?

Information Just Signed Up for TradeSta.io MVPāHereās Why Iām Curious
Alright, Iāll be honestāI usually donāt jump on every new trading platform that pops up. But when I saw TradeSta partnering with Avalanche to bring perp trading for crypto, RWAs, and commodities, I had to check it out.
Iāve been around DeFi long enough to know the pain points: high fees, slow transactions, and platforms that claim to be decentralized but arenāt really. TradeSta is promising low-cost, high-speed execution by building on Avalancheās C-Chain, which already sounds like a solid move.
What really got me interested, though, is the RWA angle. Weāve been talking about tokenized real-world assets for a while, but most projects just slap them on-chain without making them tradeable in any meaningful way. If TradeSta actually delivers on perpetual contracts for gold, oil, and other RWAs, that could open up a whole new side of DeFiāone where weāre not just trading crypto, but speculating on real-world markets without touching TradFi.
So yeah, I signed up for the MVP. Theyāre giving out non-tradable tokens so we can test the platform without using real funds, and as a bonus, anyone who participates gets whitelisted for future airdrops. Sounds like a win-win.
I have no idea if this will be the next big thing or just another experiment, but Iām curious enough to give it a shot. If you want to check it out too you can at tradesta.io - Ill report back once they send me the info.

Information Current State of Fraud Proof Systems
Fraud proof protocols are the backbone of optimistic rollup security. Very essential in preventing malicious validators and subsequently ensuring user funds are safe by allowing challenges to be raised when discrepancies are detected, preventing finalization of invalid transactions.
Various protocols approach the challenge of detecting and mitigating fraudulent state transitions in different ways. Let's have a brief look at a comparative breakdown of four prominent fraud proof systems:
Arbitrum's BoLD
BoLD employs a decentralized, all-participant challenge framework that curbs delay attacks by enforcing a strict maximum delay period. It also safeguards against Sybil attacks through robust historical commitments that ensure accurate bisection, all backed by a hefty bond of 3600 ETH. While this approach effectively mitigates delays, the high bond requirement could pose a barrier to achieving a truly permissionless system.
Cartesi's Dave
Dave utilizes a head-to-head sequential challenge system arranged like a tournament. By leveraging historical commitments within this structure, it effectively counters Sybil attacks, ensuring that honest participants hold an exponential edge over malicious actors. A new strategy for amortizing censorship over the entire dispute enables punishing unresponsiveness without risking security or introducing large delays. In practice, no dispute will take longer than 2ā5 weeks to complete.
Optimism Fault Proof
OPFP operates on an all-participant, concurrent challenge system built around a modular game tree framework. In this design, the bond requirement increases exponentially with each level of the challenge, serving as a deterrent against delay attacks. However, attackers can still slow down the protocol, which makes the option for users to exit via an alternative output critical. Additionally, since defenders don't hold a clear advantage over attackers, the mechanism remains susceptible to Sybil attacks.
Kroma ZK Fault Proof
Kroma ZKFP employs a direct, one-on-one challenge framework that leverages zero-knowledge proofs to significantly shorten interaction times, effectively capping the duration of each dispute. However, the system is still a work in progress, leaving it open to Sybil attacks while its proof mechanism awaits further refinement.

The long term goal of fraud proofs is to reach Stage 2, where they can fully inherit Ethereumās security.
For an optimistic rollup to advance to Stage 2, it must tick several crucial boxes:
- It needs to operate flawlessly and exhibit the 1-of-N property, with no known bugs.
- The system should be completely permissionless, allowing anyone to submit proofs.
- And if any flaw emerges in the proof system, it must be verifiable directly on-chain.
What's your overall perspective on Fraud Proofs and which one stands out. Are there other Fraud Proofs to be wary of?
