Question

Estonia's data platform, X-Road, links individual servers through end-to-end encrypted pathways. However, some would argue that KSI is not really a blockchain architecture. please compare and contrast the characteristics of a blockchain architecture to the features of a Keyless Signature Infrastructure like that used in Estonia. (When comparing, please compare KSI to the traditional implementation of Blockchain as the backbone of the BitCoin Cryptocurrency)

PLEASE SHOW TWO GREAT SOURCES FOR THIS

Explanation / Answer

Comparison between Traditional block chain with KSI with respect to Bitcoin is given below: -

Scalability: - KSI provides scalability linear to time O(t) and independent of time whereas scalability in bitcoin provided linear to the number of transactions O(n). Similarity between the two is that both provide global scalability.

Settlement time: - time taken by Traditional block chains to process a transaction may vary from 5-15 min whereas KSI provides very fast settlement time about 1 sec.

Data Privacy: - KSI provides high data protection and no data is disclosed, whereas data is added to block chains.

Key Management: - both KSI and traditional block chain do not require keys. And are called keyless architecture. It is keys need not to be managed. They use hashing technique for securing the data.

Quantum threat: - Block chain or bitcoin are vulnerable to quantum threat hence exposing risk of getting hacked, whereas KSI is not influenced by quantum threats thus providing more security.

Portability: - KSI authenticity can be verified even if data crosses its demographic or organizational boundaries thus making use of KSI even more convenient.

Independent Verification: - bitcoin needs to be verified by trusted authority but KSI can be verified and validated independently.
