An Ethereum (ETH) 2.0 Proof-of-Stake (PoS) testnet beacon blockchain is now live. Preston Van Loon, co-founder of sharding development firm Prysmatic Labs, announced the development in a Medium post on May 7. Ethereum 2.0 is an upcoming new Ethereum chain featuring improvements in security, scalability, and decentralization. Ethereum 2.0 would not be introduced to the current Ethereum network by means of a hard fork. Instead, users will be able to transfer value from the current Proof-of-Work (PoW) chain via a one-way smart contract. The announcement also notes that shards are a core concept behind Ethereum 2.0. Shards are individual chains …
Reducing the amount of hacking by improving cybersecurity should be considered a top priority for the crypto industry, said Kim Grauer, director of research of blockchain intelligence firm Chainalysis. As pointed out by the firm, this year could outpace 2021 in terms of crypto stolen through hacks. The vast majority of these exploits have been targeting the field of decentralized finance. “This can't go on in the industry because people are going to lose faith in investing in DeFi platforms”, Grauer said in an interview with Cointelegraph. Unlike centralized exchanges, which have improved their resiliency to crypto hacks, decentralized protocols …
Private transactions cryptocurrency PIVX and over 200 other blockchains are vulnerable to attackers obtaining disproportionately high staking rewards. A major staking vulnerability Cryptocurrency consulting firm Lunar Digital Assets claimed in a post published on its website on Aug. 12 that a staking vulnerability is being used across PIVX and its forks. The weakness reportedly allows the attacker to obtain mathematically impossible staking rewards on vulnerable proof-of-stake (PoS) chains. According to the post’s author, the PIVX development team claimed to have solved the issue in January. Nonetheless, a core developer of PoS altcoin BitGreen (BITG) noticed that the vulnerability in question …
