Explanation
Statement I is the standard definition: each block contains a cryptographic hash of the previous block. Public (permissionless) blockchains that anyone can read, such as those of Bitcoin and Ethereum, are widely used by cryptocurrencies. So both statements are true.कथन I मानक परिभाषा है: प्रत्येक ब्लॉक में पिछले ब्लॉक का क्रिप्टोग्राफिक हैश होता है। सार्वजनिक (permissionless) ब्लॉकचेन, जिन्हें कोई भी पढ़ सकता है, जैसे बिटकॉइन और एथेरियम, क्रिप्टो मुद्राओं द्वारा व्यापक रूप से प्रयुक्त होते हैं। अतः दोनों कथन सत्य हैं।More Information and Communication Technology (ICT) questions
