Blast network hits $400M TVL, rebuts claim that it’s too centralized

Web3 protocol Blast community has gained over $400 million in whole worth locked (TVL) within the 4 days because it was launched, based on knowledge from blockchain analytics platform DeBank. However in a Nov. 23 social media thread, Polygon Labs developer relations engineer Jarrod Watts claimed that the brand new community poses important safety dangers as a result of centralization.

The Blast group responded to the criticism from its personal X (previously Twitter) account, however with out straight referring to Watts’ thread. In its personal thread, Blast claimed that the community is as decentralized as different layer 2s, together with Optimism, Arbitrum and Polygon.

Blast community claims to be “the one Ethereum L2 with native yield for ETH and stablecoins,” based on advertising and marketing materials from its official web site. The web site additionally states that Blast permits a consumer’s steadiness to be “auto-compounded” and that stablecoins despatched to it are transformed into “USDB,” a stablecoin that auto-compounds via MakerDAO’s T-Invoice protocol. The Blast group has not launched technical paperwork explaining how the protocol works, however it says they are going to be revealed when the airdrop happens in January.

Watts’ authentic submit stated Blast could also be much less safe or decentralized than customers understand, claiming that Blast “is only a 3/5 multisig.” If an attacker will get management of three out of 5 group members’ keys, they will steal the entire crypto deposited into its contracts, he alleged.

In response to Watts, the Blast contracts could be upgraded through a Secure (previously Gnosis Secure) multisignature pockets account. The account requires three out of 5 signatures to authorize any transaction. But when the non-public keys that produce these signatures turn into compromised, the contracts could be upgraded to provide any code the attacker needs. This implies an attacker who pulls this off may switch all the $400 million TVL to their very own account.

As well as, Watts claimed that Blast “isn’t a layer 2,” regardless of its growth group claiming so. As a substitute, he stated Blast merely “accepts funds from customers” and “stakes customers’ funds into protocols like LIDO” with no precise bridge or testnet getting used to carry out these transactions. Moreover, it has no withdrawal operate. To have the ability to withdraw sooner or later, customers should belief that the builders will implement the withdrawal operate in some unspecified time in the future sooner or later, Watts claimed.

Moreover, Watts claimed that Blast incorporates an “enableTransition” operate that can be utilized to set any sensible contract because the “mainnetBridge,” which implies that an attacker may steal the whole lot of customers’ funds while not having to improve the contract.

Regardless of these assault vectors, Watts claimed he didn’t imagine Blast would lose its funds. “Personally, if I needed to guess, I don’t assume the funds might be stolen,” he said. However he additionally warned that “I personally assume it’s dangerous to ship Blast funds in its present state.”

In a thread from its personal X account, the Blast group stated that its protocol is simply as protected as different layer-2s. “Safety exists on a spectrum (nothing is 100% safe),” the group claimed, “and it’s nuanced with many dimensions.” It might appear {that a} non-upgradeable contract is safer than an upgradeable one, however this view could be mistaken. If a contract is non-upgradeable however incorporates bugs, “you’re useless within the water,” the thread said.

The Blast group claims the protocol makes use of upgradeable contracts for this very cause. Nevertheless, the keys for the Secure account are “in chilly storage, managed by an impartial celebration, and geographically separated.” Within the group’s view, it is a “extremely efficient” technique of safeguarding consumer funds, which is “why L2s like Arbitrum, Optimism [and] Polygon” additionally use this technique.

Blast isn’t the one protocol that has been criticized for having upgradeable contracts. In January, Summa founder James Prestwich argued that the Stargate bridge had the same problem. In December 2022, the Ankr protocol was exploited when its sensible contract was upgraded to permit 20 trillion Ankr Reward Bearing Staked BNB (aBNBc) to be created out of thin air. Within the case of Ankr, the improve was carried out by a former worker who hacked into the developer’s database to acquire its deployer key.
