An investigation led by CoinDesk has revealed that two brothers — Ian Macalinao and Dylan Macalinao — used pseudonymous developer profiles to inflate the TVL on Solana by $7.5 billion.

Sybil Attacks

The information is a warning to those that could also be skeptical of the feasibility of a real-world Sybil attack on the crypto ecosystem. According to Binance Academy, a Sybil attack is “a kind of security threat on an online system where one person tries to take over the network by creating multiple accounts, nodes or computers.”

Kevin Owocki, Co-Founder of Gitcoin, opened EthCC[5] by talking concerning the potential dangers of Sybil assaults in his discuss “Sybil Resistance for a more democratic web3.” The rising reputation of the idea of DeSoc, social graphs, and Soulbound tokens coincides with the will to cut back the probability of efficient Sybil assaults.

However, to reply the query of whether or not this can be a actual risk, we will look to the report from CoinDesk that particulars how the Macalinao brothers had been in a position to create fake developer profiles to simulate group improvement.

In the world of web3, nameless developer profiles are much more widespread than in different industries, with probably the most well-known crypto developer being the infamous Satoshi Nakamoto, creator of Bitcoin.

Developer conferences in web3 typically seem like the under Google Meet name, with all individuals contributing from behind their digital identities.

A Hackermoon article from February 2022 commented on the present state of anon developers in crypto:

“If Satoshi was present to witness how we have tweaked anonymity to suit our preferences, he might have to reconsider his stance on decentralization. Because total decentralization would cripple adoption, especially now that scams keep springing up.”

The Macalinao brothers

According to the CoinDesk investigation, Ian Macalinao has been constructing tasks as “11 purportedly independent developers” to create an inflated TVL on the Solana blockchain. CoinDesk alleged Ian authored an unpublished weblog publish from March 26 that reads:

“I devised a scheme to maximize Solana’s TVL: I would build protocols that stack on top of each other, such that a dollar could be counted several times… I believe it contributed to the dramatic rise of SOL”

The brothers used varied nameless identities to construct a network of protocols that might make the most of double-counted property to inflate the entire TVL of the ecosystem artificially. Ian allegedly defined, “I wanted to make it look like a lot of people were building on our protocol;” — a primary instance of a Sybil attack.

Dylan even went so far as to personally tweet that he felt “comfortable staking [his] own crypto in [the] project” Sunny Agreggator, now believed to have been developed by the brothers.

The pair seem to have used their public identities to shill tasks they labored on to bolster adoption anonymously. In the under tweets, the alleged pseudonyms for Ian Macalinao, Surya Khosla, and GokiProtocol appear to have thanked themselves for constructing web3 instruments for the group.

The CoinDesk article explains intimately how the brothers manipulated the Solana DeFi ecosystem, which got here at a time when Solana was simply rocked by the Slope Finance wallet exploit.

Sybil Resistance

The Gitcoin passport goals to deal with the difficulty highlighted by fake developer profiles by permitting builders to “grow a decentralized identity record with various credentials about you.”

Soulbound tokens (SBTs) are one other know-how that may assist construct Sybil resistance via non-transferable NFT tokens tied to a particular pockets. When Vitalik Buterin, founding father of Ethereum, launched the idea of SBTs, he said, “a common criticism of the “web3″ space as it exists today is how money-oriented everything is.”

The alleged exploitation of the Solana DeFi ecosystem by the Macalinao brothers reinforces the power of Vitalik’s criticism. The brothers allegedly constructed an elaborate community of DeFi tasks to inflate the TVL of DeFi on Solana — a financial objective.

Vitalik concluded his presentation on SBTs by declaring, “we need more effort on thinking through and solving these challenges” concerning the transferability of “identity objects” within the web3 house. One core “identity object” is the identification of developers constructing in an open-source ecosystem.

While decentralization and “DeSoc” could also be a long-term objective for a lot of in web3, a important downside that has not but been resolved is that of Sybil resistance. If two younger developers from Texas can idiot a complete ecosystem of the existence of $7.5 billion, then one thing will not be proper.
