• Why is Libereka built on the Blockchain?

  At its most basic and simplified state, the Libereka Blockchain is a stackable certification solution, which we are calling as the blockchain for learning or education. This stackable way of organising or linking certifications is to enable a validated, personalized certification procedure covering both formal learning (e.g. certification, degrees, micro-credits) and informal learning (e.g. badges, skills, and experiences). Our objective is that each learner or student should have a Blockchain aFew readers

• How secure is the blockchain?

  A blockchain is innately secure. It utilises powerful cryptography to give individuals ownership of an address and the crypto assets associated with it, through a combination of public and private keys, made up of combinations of random numbers and letter. This solves the issue of stolen identity as addresses are not directly associated with users’ identity, whilst also being far harder to compromise. Private keys are even more secure as they are considerably longer. It is in this way that blockFew readers

• What is Blockchain?

  A blockchain is a growing list of records, called blocks, which are linked using cryptography. Each block contains a cryptographic hash of the previous block, a timestamp, and the transaction data. The linked blocks form a chain. This iterative process confirms the integrity of the previous block, all the way back to the original genesis block.

• Will I be able to edit or delete my records on the blockchain?

  Encryption and hashing are fundamental to the blockchain technology. In short, hashing is a one-way transformation of data to an unreadable piece of data (which is knows as the hash value). With encryption you can have a two-way transformation: You encrypt data with a certain key, so it becomes unreadable. With this key, you can always decrypt this unreadable piece of data to the original value. What this mFew readers

• How can I upload documents into my Blockchain account?
