Miners
Advantages
DDoS Resistance
Immutable audit trail
High throughput possible
Scalability
Disadvantages
High computation requirements
Firewall partitioning attacks
Coarse-grained timestamps
A miner can influence timestamps
A miner can influence transaction access and order
Examples
Bitcoin, EthereumSlide8
Leader-based

Leader
Advantages
Low computation requirements
Immutable Audit
Moderate Throughput
1000s of
tps
, seconds latency
Fault Tolerant
Disadvantages
Designed for ‘fault’ tolerance, not ‘attack’ tolerance
Susceptible to DDoS attacks
Leader can influence transaction access and order
No fair timestamps
Low Scalability
