2. INTRODUCTION
• Shared distributed digital ledger
• Allows every event that a piece
of data undergoes
• As each event occurs,
information on the event is
added as a ‘block’ connected
3. • As the data in the blockchain is
recorded on a distributed, peer-
to-peer basis, it creates an ever-
growing, permanent record that
cannot be altered retroactively
• the sequence of blocks cannot be
changed without it affecting all
subsequent blocks.
13. CHALLANGES
• Change management and
governance terms of Blockchain
ecosystems
• Blockchain cannot address all the
barriers to Healthdata sharing.
• Uncertainties around the use of the
public Blockchains in healthcare.
14. • Lack of interoperability
the ability to automatically interpret the
information exchanged meaningfully and
accurately in order to produce useful results
as defined by the end users of both systems.
• Compliance of Blockchains with
privacy regulations
