Firo, the privacy-oriented cryptocurrency, has suffered a 51% attack, which resulted in the blockchainblockchain having to be significantly reorganized.
“We are under 51% attack at the moment. We recommend not to make transactions during this time until the network returns to a normal state,” the team revealed earlier on Wednesday.
Zcoin rebranded to Firo in November 2020 while continuing to utilize the same blockchain. Last week, an update called Lelantus was activated on Firo’s mainnet, bringing zero-knowledge proofs as part of the “on-by-default” privacy feature that ensures transactions sent by official Firo wallets stay hidden.
Repeated 51% attacks on the Ethereum Classic network are a source of “increasing frustration,” according to Terry Culver, CEO of Ethereum Classic Labs. “Three attacks in one month will tell you that security is an issue on Ethereum Classic,” Culver told Decrypt media partner Forkast.News in a video interview. "Increasing frustration is definitely the best way to describe it.” The threat of 51% attacks on proof of work blockchains is a “universal problem,” Culver said. “We believe and know that...
According to Changpeng Zhao, the CEO of Binance, the blockchain reorg was 306 blocks deep. “51% attack, 306 blocks rolled back, to 2021-01-18 17:24:20(UTC). Another messy situations,” said Zhao.

Before the attack, the price of Firo soared to a five-month high of $7.10, only to crash by more than 15% afterwards. Currently, the coin is trading around $4.95.
The team is yet to share further details, though they’ve said that this is “not a coding error but a nature of PoW.”
Details of the attack shared on the project’s Telegram group showed the attacker orphaned the previously confirmed transactions, and the blocks mined by legitimate pools were catching up on those abandoned transactions.
According to the Firo team, the attack would be near to impossible had they already deployed Chainlocks, a secondary validation layer aimed at mitigating this type of attacks.
We are working with exchanges and pools currently. Chainlocks that would have prevented this were being tested on testnet and was weeks away from deployment.
— Firo (formerly Zcoin) (@firoorg) January 20, 2021
However, in a thread detailing the specifics of a reorg attack, Dr. Emin Gün Sirer, who is leading the Avalanche protocol project, insists that Chainlocks is only a “temporary” fix and can’t be “considered safe or sound.”
51% attacks are not anything new to cryptocurrencies relying on the proof-of-work consensus mechanism. As reported by Decrypt, Ethereum Classic went through several of such incidents last year.
Perhaps, Satoshi was right.
Decentralized oracle network Chainlink unveiled a new incentive system Monday called Chainlink Rewards, which is designed to provide ecosystem tokens from projects in its Build program to ecosystem participants and stakers of the LINK token. The program’s first launch is through a collaboration with infrastructure firm Space and Time, a member of Chainlink Build that will provide 4% of the supply of its SXT token to eligible LINK stakers. “The Season Genesis pilot is an experiment, informing ho...
A Dubai family office managing assets for Qatari royal Sheikh Nayef bin Eid Al Thani will finance a $8.8 billion blockchain and digital assets project in the Maldives.

The investment, scheduled to roll out over five years, exceeds the country’s entire GDP,...
Actor and noted crypto critic Ben McKenzie is set to make his directorial debut at SXSW London with the June premiere of his documentary, “Everyone Is Lying to You for Money,” according to a report by Deadline. The documentary follows McKenzie—best known for roles on "The O.C." and "Gotham"—as he investigates the cryptocurrency world and interviews key figures, including during a trip to El Salvador to examine President Nayib Bukele's regime, which made Bitcoin legal tender in 2021. “When I star...
