Cloud-based storage services have always faced the same question mark since they started to spread among users: How safe are they? At first, it was not easy for the user, who is accustomed to keep the data he has on his own physical hardware, to entrust it to server fields that he did not see and did not know at once.
On the other hand, the heavy-loss attacks of popular cloud storage services like Dropbox every two or three years showed that the user’s initial concerns were partially in place. Dropbox, Google Drive and other services have tried to make up for this with their user-friendly experience and constantly increasing functionality.
However, awareness of the privacy and security of personal data is increasing day by day. There is a need for solutions that focus entirely on data security and privacy, especially in scenarios where corporate data is kept.
The new solution called TransferChain, which keeps data in the cloud and recording on the blockchain, aims to respond to this need. TransferChain, which was incorporated under the leadership of Berke Şipka, Mert Başer, Tuna Özen and Çağatay Tengiz, continues its development process with a team of 13 people. Tuna Özen, one of the founding partners, describes this structure as “a blockchain-based cloud initiative that enables users to store, process and distribute their data without compromising their privacy and security.”
Blockchain era in cloud storage
As you can guess from the name of TransferChain, blockchain technologies are used to make data storage and transfer needs more secure. The service essentially renews a standard cloud storage service with an approach where data is kept in a distributed structure and the entire record is protected on the blockchain. The files uploaded to the service, which are planned to meet the user in the form of desktop and mobile applications in the first place, are encrypted and fragmented before upload and distributed to a number of leading cloud storage services such as AWS.
All of the records such as which file is divided into how many parts and which services are kept are processed on the blockchain. In this way, even in the event of a possible attack, it is not possible for hackers to collect these “multi-threaded” files from all over the world and turn them into meaningful information. Keeping all kinds of transaction records regarding the data on the blockchain protects the system against external intervention.
“We use the blockchain instead of the database. This allows us to access this transparent but confidential and secure data storage methodology as it is stored in public ledgers and copied on machines participating in the network.”
Data security first
After the meeting with Tuna Özen, I had the opportunity to test the product for a while. In TransferChain, which is still in beta, cloud storage, file transfer and instant messaging services are offered separately. According to the information provided, it is planned to have nearly 20 functions in the final product. Privacy comes first at every step. The process works with an integrated approach that includes multiple encryption methods. For example, addresses similar to hash codes are used instead of usernames.
Of course, this is not a familiar experience for the standard user dealing with username and password. Still, TransferChain underlines that it will not compromise on privacy and security at this point. Care:
“The more user-friendly it can be without compromising privacy and security, the more user-friendly it will be. But we will not risk people’s privacy to add new functionality to the application. It will be as user-friendly as possible without compromising privacy.”
On the shelves in the second quarter
When we asked the roadmap for the product, we learned that TransferChain, which is currently in the early access stage, will be launched in the second quarter of 2021. At least the development team’s plans are in this direction; According to Özen’s statement, the desktop application will be released first. Mobile applications will follow. We will only be able to see how TransferChain will be accepted by the user after this.
