Blockstack is focused on building the new hidden layer of the decentralized internet, by creating an easy-to-use infrastructure for future app builders to create on. They are making the building blocks of the new internet. The team argues that there are centralized points of failure in the hidden layer underneath the current internet, such as the Domain Name System (DNS, the central registry for all website names) or Certificate Authorities (CAs, they approve the https tag on websites). By decentralizing these vulnerable points of trust and recording things like domain names on the blockchain, Blockstack hopes to make the internet’s structure safer.
Web addresses are held on a centralized DNS server, so they are susceptible to attacks like DDoS or spoofing.
