Kev mentioned Dan's explanation of DPoS = BFT

DPoS + BFT part 1
Dan's Video

Summary of the Video

DPoS: Delegated Proof of State BFT: Byzantine Fault Tolerance

Goals: decentralized power:

no censorship over the inclusion of transactions
applying state machine to arrive at the consensus state

Consensus Algorithm

latency to first confirmation

BFT:
disagreements -> Byzantine Failure / Half General Attack
Generate Cryptographic proofs -> who is byzantine Generals are / who is at fault
-> Penalize the party (forfeit bond / exclude from community) -> No longer block producers

Process Explanations: traditional BTS & Steemit

(ignore election process)

every 3 sec, one bp, one block
gap when one BP down

Ensure Honesty & Sustainability

Methods 1 Longest Chain is the Consensus Chain

21 bp -> full speed -> long chain
10 bp -> half speed -> shorter chain
Only when the new chain's length longer than(equal cannot) current chain, switch to new chain.

Model works even 1 bp(honest)

support election
elect new bp

Methods 2 Last Irreversible Block (in Steemit)

2/3 of bp built upon
Prevent longer range attack avoid sb got old key, and create alternative blockchain.
Analogy: software download
In reality:
99% participation: like Steemit & BitShares enjoy
