Advantages of blockchain technology
BC is a distributed P2P ledgers that makes it possible to share a record of transaction with a great number of participants
Transactions cannot be manipulated, abused or changedEach participant (node) has a full copy of the ledgerHigh level of data securityTransactions are recorded based on consensus model between participantsCryptography is used for bot hidentity and integrity - PKI and hash

Possible legal issues and challenges related to
blockchain technology
Validity of contractsProof of relationship/contractBoth can be managed, especially in a B2B context
SLA /availabilityLiability
The elephant in the room…
GDPR
![Page 10: Blockchain: challenges and legal issues of new technology · 2018-04-26 · Advantages of blockchain technology BC is a distributed P2P ledgers that makes it possible to share a record](https://reader034.vdocuments.site/reader034/viewer/2022042114/5e9136e3329f6d137819a304/html5/thumbnails/10.jpg)
A few basic principles of GDPR
TransparancyData Protection by designData minimisationAccuracyLimited retention timeData securityPurpose limitation
Right to erasureRight to be forgotten
Data storage within EU
![Page 11: Blockchain: challenges and legal issues of new technology · 2018-04-26 · Advantages of blockchain technology BC is a distributed P2P ledgers that makes it possible to share a record](https://reader034.vdocuments.site/reader034/viewer/2022042114/5e9136e3329f6d137819a304/html5/thumbnails/11.jpg)
Possible privacy issues in Blockchain
Distinction should probavbly be made between
Private BC (permission based) Public BC (permissionless)
Everyone can participate Control over participants IDEveryone has acces Access and use managementNo control over location of data Acceptance of ToU prior to access
Location of data can be managed
![Page 12: Blockchain: challenges and legal issues of new technology · 2018-04-26 · Advantages of blockchain technology BC is a distributed P2P ledgers that makes it possible to share a record](https://reader034.vdocuments.site/reader034/viewer/2022042114/5e9136e3329f6d137819a304/html5/thumbnails/12.jpg)
Inherent privacy issues in Blockchain
Data subjects rights (errasure, correction, right to be forgotten, …)Data minimisationLimited retention timesApplicable (data protection) laws (public vs. Private BC)Purpose limitation(Control over) data security (even if BC is in itself “secure”)Accuracy of data and right of correction >< in principle, data in BC cannot be changed
Data export / Location of data storage (public vs. private BC)Identity of data controller / data ownership

Inherent privacy issues in Blockchain
ConsequenceStoring personal data on a BC is not an option under GDPR
The workaroundYou store the personal data off-chain and store the reference to this data, along with a hash of this data and other metadata (like claims and permissions about this data), on the blockchain. Personal data is then send P2P between users
ButLoss of control over who accessed / stored / used personal data, since it is no longer in BC Necessity to have P2P contact with all participants in the BC

Where Blockchain can be a helping hand
(technical) data security
Guaranteed quality of data / reliability of data / accuracy
= Data protection by design
![Page 15: Blockchain: challenges and legal issues of new technology · 2018-04-26 · Advantages of blockchain technology BC is a distributed P2P ledgers that makes it possible to share a record](https://reader034.vdocuments.site/reader034/viewer/2022042114/5e9136e3329f6d137819a304/html5/thumbnails/15.jpg)
How Blockchain could even be a tool to ensure GDPR
compliance
BC could be used to execute data subject’s rights
Right to acces Right of correctionData portability
+ could be used as part of accountability / documentation obligations under GDPR

Prepare for challenges
Blockchain WILL have its breakthrough within 2 to 3 years
Blockchain offers a great number of opportunities
Users / early adapter should however be very aware of possible legal implications
Before all GDPR / data protection laws

Prepare for challenges
Detailed analyses of set up before getting started
What data?Which participants?Public or private?Location of data?Terms of Use for participants?Applicable law…
