ELIB, Explain Like I’m Boss, is a collection of executive summaries for Web 3 technologies and projects.
This ELIB lists the unique advantages of features commonly seen in Directed Acyclic Graph (DAG) and Proof-of-Stake (PoS) Blockchain structures:
DAG
Individual Transaction Based
- Faster Finality
- Easier State Trimming
- Enables Parallel Transactions
Leaderless Transaction Sequencing
- Fairer Sequencing
Full Set Validator Voting
- Better Collusion Resistance
PoS Blockchain
Batched Transaction Based
- More reliable Transaction Interoperability
Fixed Set Validator Voting
- Enables Individual Accountability → better Network Uptime
Note that mirrored disadvantages and mutual features/advantages across DAG and PoS Blockchain are intentionally omitted for conciseness.
