In the latest years, web-based ecosystems developed and consequently did the security issue, regarding the safety of the data both for the company and user side.&nbsp;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">that&#8217;s why in the latest months and years new laws concerning data treatment have been studied, discussed and approved.&nbsp;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">It is clear that every instrument if improperly used, may cause different degrees of harm.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">That&#8217;s why this concept also applies to the digital world. The <a href=\"https:\/\/affidaty.io\/blog\/en\/2019\/04\/blockchain-applications-the-future-is-here\/\" target=\"_blank\" rel=\"noreferrer noopener\" aria-label=\" (apre in una nuova scheda)\">blockchain<\/a> is the instrument that if misused, may lead to breaches in the national or supranational laws, that were put in place to safeguard the citizens.&nbsp;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">What are the most common errors that could lead the blockchain to be misused by a company?<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">A perfect example is the personal data treatment in the case in which one wants to use the blockchain to store all the user data instead of creating a private network to store sensitive information and coupling it a &#8220;notarial&#8221; blockchain. What happens?<\/p>\n\n\n\n<ol class=\"wp-block-list\"><li>The data contained inside the blockchain is tamper proof, <b>implying the impossibility (due to its coding) to cancel the data once inserted in the shared chain.<\/b><\/li><li><b>Blockchains are distributed and so is data control which is delegated to all participants<\/b> (at most miners, which cannot be considered Data Protection Officer as required by the GDPR).<\/li><li><b>Smart Contracts exist to be automated under the decisional profile<\/b>, opening non-trivial criticalities especially if litigation is brought to court.<\/li><\/ol>\n\n\n\n<p class=\"wp-block-paragraph\">Generally, <b>what collides with the GDPR, in this case, are two principles that defined until today value and power of the blockchain:<\/b><\/p>\n\n\n\n<ul class=\"wp-block-list\"><li>the data inserted is public and accessible to everyone participates in the chain<\/li><li>the data remain indefinitely stored, to secure and protect the ledger.&nbsp;<\/li><\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">The <b>GDPR<\/b> can be summarized in three words: <b>centralization, limitation and removability, or deletion<\/b>. These collide with the three base concepts of blockchain: <b>decentralization, distribution, and immutability.<\/b><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">as stated in previous paragraphs, the GDPR gives EU citizens exclusive rights concerning their personal data among which stand out:<\/p>\n\n\n\n<ul class=\"wp-block-list\"><li>the right to deletion of personal data when these are not necessary for the scope, when the user withdraws consent or when the permanent collection is illegal.<\/li><li>the right to require the correction of incorrect data<\/li><li>The right to limit data elaboration when its accuracy is contested or when it is not necessary anymore.<\/li><\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">These rights are comprehensible in a centralized database context, controlled by a single data handler with a finite set of processors.
