Core Member David Moss shares an update in Github - Dawn2.x and Dawn 3.0 have been merged into github Master branch

Refers to Thomas Cox's latest postChanges to the Way We Forecast

New Change

• message -> code
• scope auto-assign, no need assign manually
  

New Features:

• Deferred Transactions
• Staking Pools
• New Currency Contract
• New Token Standard

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

Github Issues: LLB

• track in dyanmic_global_property_object
• on disk
• to LIB when open db

Steemit and BitShares's depending states: 45secs on average, take 14 out of 21
