Output: Nodes continuously share signed data objects among themselves using push and pull messages. This allows them to manage the cluster and update their own copies with the most recent information.


Input: What is the role of push and pull messages in the Gossip protocol?

Output: Push messages are used by nodes to inform the cluster that they have information to share. Pull messages, on the other hand, are sent by nodes to ask the cluster if there is any new information available.


Input: What is the purpose of the Blockstore in the context of a wealth advisor?

Output: The Blockstore allows a wealth advisor to record every financial transaction it observes on the network, in any order, as long as it is signed by the expected leader for a given slot.

Input: What determines the rate at which loads are completed in the pipeline?

Output: The rate of completion in the pipeline is determined by the slowest stage in the pipeline. If there are infinite loads, the pipeline will consistently complete a load at that rate.


Input: What is the role of a validator in the context of blockchain?

Output: A validator receives entries from the current leader and submits votes confirming the validity of those entries.

Input: What is the role of the root node in the Turbine mechanism?

Output: The root node, located at layer 0, communicates with layer 1 and shares data with it. It is rotated every shred based on a weighted shuffle, ensuring fair distribution of data.


Input: How does the data plane fanout mechanism work in the Turbine tree?

Output: The data plane fanout mechanism determines the size of layer 1, and subsequent layers grow by a factor of the data plane fanout. Each node in a layer only needs to broadcast its data to a maximum of data plane fanout nodes in the next layer, reducing redundant transmission.


Input: How does Turbine prevent packet loss during retransmission?

Output: Turbine takes into account network-wide packet loss and propagation depth when setting the forward error correction (FEC) rate. This helps mitigate the probability of packet failure and ensures successful reconstruction of shred groups.


Input: What happens if a validator fails to reconstruct a shred group in Solana?

Input: What happens to the abandoned blocks in competing forks?

Output: The abandoned blocks in competing forks are all discarded, and only one fork will be finalized by the cluster.


Input: How do forks naturally occur in the Solana protocol?

Output: Forks naturally occur as a consequence of leader rotation, where nodes take turns being the leader and generating the Proof of History (PoH) that encodes state changes.


Input: What is the purpose of having only one leader at a time in a cluster?

Output: Having only one leader ensures that all validators can replay identical copies of the ledger, but it also minimizes the influence of a malicious leader.


Input: How does a cluster minimize the influence of a malicious leader?

Output: The cluster minimizes the influence of a malicious leader by rotating which node takes the lead, so no single node holds the leader role indefinitely.


Input: How does a validator determine the expected leader?

Output: Each validator selects the expected leader using the same algorithm, and when it receives a new signed ledger entry, it can be certain that it was produced by the expected leader.


Input: What is a leader schedule in a cluster?

Output: A leader schedule is the order of slots assigned to each leader, and it is recomputed periodically to assign slot leaders for a duration of time called an epoch.


Input: Why is the leader schedule offset important in Solana?

Output: The leader schedule offset is important because it determines how far in advance the schedule must be computed, ensuring that the ledger state used to compute the schedule is finalized.


Input: What is the purpose of using ephemeral keys in the operation?

Output: The purpose of using ephemeral keys is to ensure that the cluster can recover from the loss of all the keys used by leaders and validators, which could occur through a common software vulnerability shared by all the nodes.


Input: How are stake owners able to vote directly even if their stake is currently delegated to a validator?

Output: Stake owners are able to vote directly by co-signing a validator vote, even if their stake is currently delegated to a validator.


Input: What is the duration of each slot in an epoch?

Output: Each slot in an epoch has a duration of T PoH ticks.


Input: What should validators do if entries are not observed or if entries are invalid?

Output: If entries are not observed or if entries are invalid, the next leader must produce ticks to fill the previous leader's slot.


Input: Why should the next leader postpone sending ticks until it is confident that other validators also failed to observe the previous leader's entries?

Output: The next leader should postpone sending ticks until it is confident that other validators also failed to observe the previous leader's entries in order to ensure accurate repair requests and prevent incorrect building on its own ticks.


Input: How does Solana achieve fast and reliable synchronization?

Output: Solana achieves fast and reliable synchronization by using a technique called Proof of History (PoH), where leader nodes timestamp blocks with cryptographic proofs of time passing since the last proof.

Input: How does Solana's optimistic processing technique work?

Output: Solana's optimistic processing technique allows validators to process transactions optimistically, without delay, long before it is time to vote on their validity. If consensus is not achieved, a node can simply roll back its state.


Input: What is the role of the Proof of History (PoH) in Solana's consensus mechanism?

Output: The Proof of History (PoH) in Solana is not a consensus mechanism itself, but it is used to improve the performance of Solana's Proof of Stake (PoS) consensus by providing reliable timestamps and improving the performance of data plane protocols.


Input: How does Solana's approach to verifying its delay function compare to a verifiable delay function (VDF)?

Output: Solana's approach to verifying its delay function is proportional to the time it took to create it, while a VDF aims for very fast verification time. Solana's approach includes data hashes in its Proof of History chain, making it different from a VDF.

Input: How can a program author manage the state of a program?

Output: A program author can manage the state of a program by deciding how to manage the program's whole state, possibly as many accounts.


Input: What happens if a program violates the access policy?

Output: If a program violates the access policy, the runtime discards all account changes made by all instructions in the transaction and marks the transaction as failed.
