As we all know, the security of assets is always paramount for digital asset holders. Therefore, digital wallets used to manage keys and addresses become particularly important. Digital wallet is divided into cold wallet and hot wallet. Hot wallets are called online wallets, while cold wallets are offline wallets, also referred to hardware wallets. Once the digital wallet is stolen, the probability of being recovered is almost zero. For different types of wallets, there are distinct security problems, as to hot wallets, the security of the network environment is very important; Whereas for offline hardware wallets, the security of the hardware itself is crucial.
In terms of the independent development of the blockchain NGK, it pays particular attention to hardware wallet security at the technical level. The technical team of NGK wallet has rich industry experience and advanced technology, as well as successful cases in blockchain, cross chain, wallet, DAPP field. On the security problem of hot wallet, NGK sets up a unique security model to conduct security confrontation, and simultaneously detects the network running environment. The decentralized chain storage ensures the security of NGK wallet. Because NGK wallet does not manage the privatekey of the user, it is difficult to lose the user’s assets except that the privatekey is stolen.
With regard to hardware wallet security, NGK adopts asymmetric encryption algorithm to generate public and privatekeys, privatekey multiple encryption technology, independent privatekey and dynamic verification code dual authentication, two kinds of key cooperation to protect asset security. NGK public address can be set on the blockchain, the privatekey is kept by oneself, when the operation requires the publickey encrypted data, the privatekey is used for signature verification, and only after the signature verification is successful can the operation transaction be carried out. Certainly, in the operation should be careful to keep their wallet privatekey and mnemonic.
Based on ensuring the safety of NGK wallet, in order to improve the speed of wallet trading, the new graphene technology is adopted to achieve faster transaction processing, high performance and efficient operation. With smart contract architecture, asset registration on the chain, it ensures the uniqueness of transactions, while eliminates data fraud, tampering and information disclosure. The safety advantage of NGK hot and cold wallets is self-evident. Besides, the application of asymmetric encryption public-privatekeys will also help build trust between nodes, which is even more important for NGK security.
Currently, NGK digital wallets will support more digital currencies after the following technology upgrade in addition to native token NGK and algorithmic stablecoin USDN storage.
