Offchain Labs co-founder Ed Felten said there were one or two fraud challenges submitted on a version of Arbitrum running on the Ethereum proof-of-work fork after the Merge, which was defeated.

Arbitrum's fraud proofs haven't been used in the two years since it launched
Not a single fraud proof has been submitted on Arbitrum since it first launched its mainnet with the built-in security feature in August 2021, according to Ed Felten, co-founder and chief scientist of the Arbitrum-building Offchain Labs.
Operating as an Ethereum layer-2, Arbitrum’s interactive, multi-round fraud proofs work by allowing a layer-1 verifier contract to decide whether the challenger’s fraud-proof submission is valid. If so, the fraudulent validator’s stake is slashed.
Fraud proofs are submitted by challenging validators when it considers another validator to have fraudulently or otherwise incorrectly assembled an incoming batch of transactions into the next block.
However, Arbitrum’s mainnet is yet to see a fraud-proof attempt let alone a successful challenge, Felten told Cointelegraph at Korean Blockchain Week on Sept. 4:
“Not on mainnet. We did have one or two on Ethereum proof-of-work (POW). After the Merge, [...] there was a version of Arbitrum running on the Ethereum POW fork and somebody did try to steal all the data and there was a successful challenge which defeated that.”

Lido assures LDO, stETH tokens remain safe despite flaw in token contract
The “fake deposit” attack enables bad actors to execute a transfer where the requested value is larger than what the user actually owns.
Lido assures LDO, stETH tokens remain safe despite flaw in token contract
Ethereum staking protocol Lido Finance has assured both Lido DAO (LDO) and staked-Ether (stETH) tokens remain safe despite hackers allegedly exploiting a known security flaw in LDO’s token contract.
Lido didn’t confirm any exploits, but acknowledged the security flaw was known and reassured LDO and stETH funds remain safe in response to a Sept. 10 post by blockchain security firm SlowMist.
SlowMist said LDO’s flawed token contract allows bad actors to facilitate “fake deposit” attacks on exchanges because LDO’s token contract enables users to execute transactions even where they don’t have sufficient funds. This code deviates from the Ethereum Request for Comment 20 (ERC-20) token standard, according to SlowMist.
However, Lido Finance argued the flaw is built into all ERC-20 tokens — not just Lido’s LDO token:
SlowMist said the “fake deposit” attacks came from LDO’s token contract executing transfers where the value is larger than what the user actually owns, triggering a false return as opposed to reverting the transaction. While the firm said Lido's token contract has recently been exploited via this attack, no on-chain evidence was provided.
TON, XLM, XMR, and MKR could attract buyers if Bitcoin rises above $26,500
Bitcoin (BTC) traded in a narrow range this week and is on target to form the third consecutive Doji candlestick pattern on the weekly chart. The cryptocurrency markets did not receive any support from the United States equities markets, which ended the week on a negative note. The S&P 500 Index dropped 1.3% while the Nasdaq closed down 1.9%.
Bitcoin’s weakness has dragged several altcoins lower, with many testing multi-week lows. This indicates that the broader crypto market is in a firm bear grip. Negative markets make it difficult for buyers to identify short-term bullish trades as rallies hardly sustain. However, it could be a good time for long-term investors to build a portfolio.
Crypto market data daily view. Source: Coin360According to a recent Amberdata report, 24% of asset management firms are appointing senior executives dedicated to the implementation of digital strategies. Down the line, 13% more firms plan to adopt a digital assets strategy. This indicates “seriousness about implementation as well as senior management buy-in,” the report added.
Could Bitcoin break out to the upside, boosting buying interest in altcoins? Let’s study the charts of top-5 cryptocurrencies that are showing promise in the near term.

3 reasons why Pepe price will continue to fall in September
Pepecoin (PEPE) price has crashed nearly 85% from its record high of $0.00000448 in May 2023. What's more, its bearish momentum is likely to continue in September.
Back-to-back Pepecoin security breaches
Pepecoin has suffered two concerning security breaches in the last two weeks.
First, on Aug. 24, Pepecoin's rogue founding team members transferred $16 million worth of PEPE tokens to exchanges to potentially sell them. That created concerns across the community about a potential "rug pull scam," causing a 30% decline in the PEPE market.
Then, on Sep. 9, Pepecoin's official X (aka Twitter) handle confirmed that an anonymous entity dubbed "lordkeklol" had hacked their accredited Telegram channel.
PEPE price has dropped over 12% since the news, hinting that the back-to-back security breaches have eroded investors' confidence in the memecoin project.

Binance’s exec exodus, Nasdaq to trade AI orders and SBF loses bail appeal: Hodler’s Digest, Sept. 3-9
A key talking point in the crypto community has been the ongoing exodus of executives from Binance amid growing regulatory troubles. Binance has seen the departure of 10 key executives from various departments in the first nine months of 2023. The latest to join the list is Helen Hai, executive vice president of Binance, who announced her resignation from her post on Sept. 6. On the same day, Gleb Kostarev, vice president of Eastern Europe, Turkey, the Commonwealth of Independent States, Australia and New Zealand at Binance, also announced his resignation, as did CIS general manager Vladimir Smerkis. Four top executives from Binance reportedly all left on the same day after Binance’s response to the United States Department of Justice investigation. Binance CEO Changpeng Zhao has hosed down recent rumors against his firm, assuring its balance sheet and employee retention remain robust despite the recent market uncertainty.
The United States Securities and Exchange Commission has approved Nasdaq’s request to operate its first AI-driven order type on Sept. 8. Called the dynamic midpoint extended life order (M-ELO), the new system expands on the M-ELO automated order type by making it “dynamic,” meaning it will use artificial intelligence to update and, essentially, recalibrate itself in real-time. The follow-on effect should be a significant acceleration of orders placed with the system. Nasdaq says the dynamic M-ELO demonstrated a “20.3% increase in fill rates and an 11.4% reduction in mark-outs” during its research and testing.
Former FTX CEO Sam “SBF” Bankman-Fried lost an initial appeal to be released again on bail prior to his criminal trial. His lawyers had petitioned the court for temporary release, claiming the current measures to allow SBF to prepare for his trial were inadequate due to limited internet access. An appeals court denied the motion on Sept. 6, maintaining SBF’s detention at the Metropolitan Detention Center in Brooklyn. The former FTX CEO had his bail revoked on Aug. 11, following allegations of witness intimidation for leaking, to The New York Times, personal notes and diary entries from former Alameda Research CEO Caroline Ellison. SBF has roughly four weeks to prepare for his Oct. 3 trial.
ARK Invest and 21Shares requested the U.S. Securities and Exchange Commission to approve the listing of shares of a spot Ether ETF on the Cboe BZX Exchange. The investment vehicle, called the ARK 21Shares Ethereum ETF, will have crypto exchange Coinbase act as a custodian and will measure the performance of Ether based on the Chicago Mercantile Exchange CF Ether-Dollar Reference Rate. The proposal from ARK Invest and 21Shares is one of many spot crypto ETFs that will be reviewed by the SEC in the coming months. The U.S. regulator has been delaying decisions on crypto investments products lately, especially concerning Bitcoin spot ETF proposals.
Grayscale has told the U.S. Securities and Exchange Commission that it has no legal reasoning left to block the conversion of its flagship Bitcoin fund to a spot exchange-traded fund (ETF). The company’s lawyers sent a letter to the SEC requesting the pair meet to discuss the next steps following the regulator’s court loss regarding the conversion of the Grayscale Bitcoin Trust (GBTC) on Aug. 29. Grayscale added that it believes the SEC should conclude there are “no grounds” for treating the GBTC differently from Bitcoin futures ETFs whose filings “the Commission has previously approved.” According to Grayscale, its fund conversion application has been pending for nearly three times longer than the length of time stipulated by the SEC’s rules.
