ChainCatcher news, according to CoinDesk, the privacy-preserving computing network Nillion has completed a $25 million funding round, led by Hack VC. This funding brings Nillion's total financing to over $50 million, with investors including Hack VC, Distributed Global, and HashKey.According to RootData, Nillion is a decentralized public network based on a new cryptographic primitive called Nil Message Compute (NMC), which allows nodes in a decentralized network to operate in a unique, non-blockchain manner. Nillion unlocks important new utilities in Web3 by enabling use cases such as decentralized credit scoring, decentralized trusted execution environments, private NFTs, and decentralized secure storage services.Previously reported, in December 2022, Nillion completed a $20 million funding round, led by Distributed Global, with participation from AU21, Big Brain Holdings, Chapter One, GSR, HashKey, OP Crypto, and SALT Fund.

ChainCatcher news, Arkham CEO Miguel Morel responded to recent criticisms regarding the project potentially leaking private information, stating, "The lack of privacy is inherent to the operation of most public blockchains today."He said, "You are actually making a transaction and broadcasting it to a decentralized network of millions, where anyone can see which transactions are being broadcast on-chain. A publicly available blockchain may be the worst way to keep private information private."Morel also stated, "Arkham's main clients are traders and hedge funds—those who make money by obtaining information about large buy and sell positions on a specific token."

ChainCatcher news, Vitalik Buterin recently published a new article titled "An Incomplete Guide to Stealth Addresses," pointing out that one of the biggest challenges for the Ethereum ecosystem moving forward is privacy, and proposed the concept of "stealth addresses" as a potential privacy solution. This solution would enable the anonymization of P2P transactions, NFT transfers, and ENS registrations, thereby serving to protect users.Vitalik Buterin suggested that users receiving assets can generate and save a "spending key" to create a stealth meta-address that can be registered on ENS. This address can be passed to the transaction sender, who performs cryptographic calculations on the meta-address to generate a stealth address belonging to the recipient. The sender can transfer assets to the recipient's stealth address and can also publish a temporary key to confirm that the stealth address belongs to the recipient, with each new transaction generating a new stealth address.Vitalik Buterin added that, in addition to implementing a "key blinding mechanism," it is also necessary to adopt the "Diffie-Hellman key exchange algorithm" to ensure that the association between the stealth address and the user's meta-address is not made public, and that funds can be transferred using ZK-SNARKs technology to pay for Gas fees.
