Distributed system:

DLT(Distributed ledger technology), or call it blockchain

Blockchain: a good explanation on what is blockchain (in Chinese) https://www.zhihu.com/question/37290469/answer/167477833

decentralized: transactions happened on peer to peer. without intervening of the third party. prevent private leakage.

Commonalities between DLT and distributed system

Immutability (不变性):

The log-structured file system, log-structured merge-trees, and Copy-On-Write are common patterns/tricks used in Distributed Systems to model immutable data structures.

Blockchains are intervening distributed accounting ledgers, hence the name Distributed Ledger Technology.

Asynchrony (不同时性): no globally synchronized clock

Consensus(一致性)

Network reliability: Every block has a pointer pointing to the previous block, similar to linked list. The pointer is similar to a checksum. It is easy to detect block loss.
