 Furthermore, and much to our surprise, it can be implemented using a mechanism that has existed in Bitcoin since day one. The Bitcoin feature is called nLocktime and it can be used to postdate transactions using block height instead of a timestamp. As a Bitcoin client, you'd use block height instead of a timestamp if you don't trust the network. Block height turns out to be an instance of what's being called a Verifiable Delay Function in cryptography circles. It's a cryptographically secure way to say time has passed. In Solana, we use a far more granular verifiable delay function, a SHA 256 hash chain, to checkpoint the ledger and coordinate consensus. With it, we implement Optimistic Concurrency Control and are now well en route towards that theoretical limit of 710,000 transactions per second.

-# Replication-validation Transaction Fees
-
-**Subject to change.**
-
-As previously mentioned, validator-clients will also be responsible for validating PoReps submitted into the PoH stream by archiver-clients. In this case, validators are providing compute \(CPU/GPU\) and light storage resources to confirm that these replication proofs could only be generated by a client that is storing the referenced PoH leger block.
-
-While replication-clients are incentivized and rewarded through protocol-based rewards schedule \(see [Replication-client Economics](../ed_replication_client_economics/)\), validator-clients will be incentivized to include and validate PoReps in PoH through collection of transaction fees associated with the submitted PoReps and distribution of protocol rewards proportional to the validated PoReps. As will be described in detail in the Section 3.1, replication-client rewards are protocol-based and designed to reward based on a global data redundancy factor. I.e. the protocol will incentivize replication-client participation through rewards based on a target ledger redundancy \(e.g. 10x data redundancy\).
-
-The validation of PoReps by validation-clients is computationally more expensive than state-validation \(detail in the [Economic Sustainability](../ed_economic_sustainability.md) chapter\), thus the transaction fees are expected to be proportionally higher.
-
-There are various attack vectors available for colluding validation and replication clients, also described in detail below in [Economic Sustainability](../ed_economic_sustainability/README.md). To protect against various collusion attack vectors, for a given epoch, validator rewards are distributed across participating validation-clients in proportion to the number of validated PoReps in the epoch less the number of PoReps that mismatch the archivers challenge. The PoRep challenge game is described in [Ledger Replication](https://github.com/solana-labs/solana/blob/master/book/src/ledger-replication.md#the-porep-game). This design rewards validators proportional to the number of PoReps they process and validate, while providing negative pressure for validation-clients to submit lazy or malicious invalid votes on submitted PoReps \(note that it is computationally prohibitive to determine whether a validator-client has marked a valid PoRep as invalid\).
