Blockchain claim to be immutable. Is that true?

C

There is a strong claims that Blockchain brought immutability of the record, once it has been created no one could delete it, it will serve as proof of authencity and useful for auditability.

Without thinking deeply, those new to Blockchain Technology will completely TRUST and agree that, such technology really solve the TRUST problem. But, only the incident could proof that those claims is not 100% right if you implement it wrong.

In Bitcoin Blockchain 51% attack could change every record in Blockchain system.

A simple mistake in Smart Contract, could make Decentralized Application Organization go bankruptcy.

If Human is in the loop everything could be possible, a delete feature could be implemented so that, we can delete the record that we have been created, only the shadow is remaining (the transaction of the record). But if the transaction is not transparent, you will never know that those record does exist.

Blockchain seems to have a big promise, but without using your critical mind, Blockchain is just a dream.

តាមទ្រឹស្តីគឺយើងមិនអាចកែប្រែបានទេ នៅពេលដែលយើងធ្វើប្រតិបត្តិការរួច

ការកែប្រែ គឺជាការបង្កើតប្លុកថ្មី មានន័យថា ប្លុកទី១គឺការបង្កើត ប្លុកទី២គឺការកែប្រែ នោះមានន័យថា គ្រប់សកម្មភាពរបស់យើងត្រូវការកត់ត្រាទាំងអស់មិនថាយើងបង្កើត កែប្រែ ឬ លុបចោលនោះទេ។

ចំពោះរឿងកែប្រែទិន្នន័យ៧ថ្ងៃនោះវាមិនមែនជាមុខងាររបស់បច្ចេកវិទ្យាប្លុកឆេនទេ តែវាជាមុខងារបន្ថែមរបស់ក្រុមហ៊ុនប្លុកឆេនណាមួយដែលបង្កើតអោយមានមុខងារមួយនេះ ថាមុន៧ថ្ងៃកែប្រែបាន ក្រោយ៧ថ្ងៃកែលែងបាន។ ហេតុដូចនេះមុខងារនេះមិនទូទៅសម្រាប់ប្លុកឆេនដទៃឡើយ។

តើយើងអាចកែប្រែទិន្ន័យដែលលើសពី៧ថ្ងែនៅលើblockchian បានមែនទេបង?
