Earlier in September, Cointelegraph reported that Israeli cybersecurity startup GK8 had raised $4 million to finance its offline cryptocurrency transaction solution. The company developed a cold wallet with “hot wallet functionalities” that is completely shielded from online hackers because it does not require an internet connection.
Apart from creating additional security layers, offline transactions could, in theory, enable complete censorship resistance for cryptocurrencies. Being able to sign, send, validate, receive and record value transfers without the internet might also be the key to ensuring global cryptocurrency adoption.
