Welcome to the Cerberus Infographic Series, where we take an in-depth look at how Cerberus, Radix’s unique consensus protocol, will provide the unlimited, frictionless scalability required to bring Decentralized Finance (DeFi) to billions of people.

Today’s chapter is Chapter VII:

• Episode 14: Maintaining a Record of Transactions: We explain that nodes maintain a record of the entire transaction plus proof that sufficient vote weight had validated and approved it.

• Episode 15: Sybil Resistance Through Proof of Stake: We describe what a Sybil attack is and how Radix’s use of its Delegated Proof of Stake (DPoS) system weights votes to protect the network from such attacks.
  

• Episode 16: Conclusion: We revisit the title of the infographic, summarizing how it is Radix’s unique design that allows it to achieve the scalability, atomic composability, decentralization, and security that are required if DeFi is to scale to meet the financial needs of billions of people.

Here’s the running order:

Chapter I: Introduction; Summary; Why Blockchains Can’t Scale

Chapter II: What is Radix?; The Shardspace and Validator Sets

Chapter III: Substate; Substate and Transactions

Chapter IV: Shard Allocation; Transactions

Chapter V: Nakamoto vs BFT-style Consensus; Consensus - Local Cerberus

Chapter VI: Consensus - Emergent Cerberus; Partial Ordering - Parallelization of Processing

Chapter VII: Maintaining a Record of Transactions; Sybil Resistance Through Proof of Stake; Conclusion
