SOLANA team eliminated vulnerability

SOLANA Foundation and Jito teams were directly associated with validators to eliminate the identified vulnerability. Bug was discovered by Anza experts.

The error concerned the evidence program ZK Elgamal and theoretically affected confidential tokens released under the TOKEN-2022 program.

The bug consisted in the fact that some algebraic components were not included in the hash when converting Fiat Shamami. An experienced attacker could use a vulnerability to create fake evidence. This allowed him to perform unauthorized actions, including the release of an unlimited number of coins and withdrawing them from any account.

Experts discovered an error on April 16 and the very next day they began to spread a patch to eliminate it. To solve a similar problem in another area of ​​the code base, a second correction was needed. Most NOD operators made the necessary changes in the evening on the evening of April 18.

“Since the error limited the solution of ZK Elgamal Proof, updates were not required for the TOKEN-2022 program. All funds are safe, and there are no well -known exploits of potential vulnerability, ”the Solana Foundation team said.

One of the commentators noted that the correction of a bug without publicity, simply by agreement with more than 70% of the validators, indicates the possibility of arranging a “zero day” on Solana.

“These are the same people who achieve 70% [консенсуса] On Ethereum. All validators Lido, Binance, Coinbase and Kraken. If the geth needs to release a patch, I will be glad to coordinate their actions, ”the co -founder of SOLANA, Anatoly Yakovenko, defended the actions of the team.

At the end of April, the organization, standing behind the project, announced measures to increase the decentralization of the network.

According to BlockWorksin SOLANA there are 1218 active validators. According to data Ethernodesthe work level of Ethereum supports 17 126 NODs, operators 11 025 of which use the GETH agent. At the same time, 28% of the total emission of ETH were blocked in stakeing, SOL has 65%.
