-Small, frequent PRs are much preferred to large, infrequent ones. A large PR is

 ### How big is too big?

-If there are no functional changes, PRs can be very large and that's no
-problem. If, however, your changes are making meaningful changes or additions,
-then about 1.0.1 lines of changes is about the most you should ask a Solana
-maintainer to review.
+If there are no functional changes, PRs can be very large and that's no problem. If,
+however, your changes are making meaningful changes or additions, then about 1,000 lines of
+changes is about the most you should ask a Solana maintainer to review.

 ### Should I send small PRs as I develop large, new components?

-Add only code to the codebase that is ready to be deployed. If you are building
-a large library, consider developing it in a separate git repository. When it
-is ready to be integrated, the Solana maintainers will work with you to decide
-on a path forward. Smaller libraries may be copied in whereas very large ones
-may be pulled in with a package manager.
-
-## Getting Pull Requests Merged
-
-There is no single person assigned to watching GitHub PR queue and ushering you
-through the process. Typically, you will ask the person that wrote a component
-to review changes to it. You can find the author using `git blame` or asking on
-Discord.  When working to get your PR merged, it's most important to understand
-that changing the code is your priority and not necessarily a priority of the
-person you need an approval from. Also, while you may interact the most with
-the component author, you should aim to be inclusive of others. Providing a
-detailed problem description is the most effective means of engaging both the
-component author and other potentially interested parties.
-
-Consider opening all PRs as Draft Pull Requests first. Using a draft PR allows
-you to kickstart the CI automation, which typically takes between 10 and 30
-minutes to execute. Use that time to write a detailed problem description. Once
-the description is written and CI succeeds, click the "Ready to Review" button
-and add reviewers. Adding reviewers before CI succeeds is a fast path to losing
-reviewer engagement. Not only will they be notified and see the PR is not yet
-ready for them, they will also be bombarded them with additional notifications
-each time you push a commit to get past CI or until they "mute" the PR. Once
-muted, you'll need to reach out over some other medium, such as Discord, to
-request they have another look. When you use draft PRs, no notifications are
-sent when you push commits and edit the PR description. Use draft PRs
-liberally.  Don't bug the humans until you have gotten past the bots.
-
-### What should be in my PR description?
-
-Reviewing code is hard work and generally involves an attempt to guess the
-author's intent at various levels. Please assume reviewer time is scarce and do
-what you can to make your PR as consumable as possible. Inspired by techniques
-for writing good whitepapers, the guidance here aims to maximize reviewer
-engagement.
-
-Assume the reviewer will spend no more than a few seconds reading the PR title.
-If it doesn't describe a noteworthy change, don't expect the reviewer to click
-to see more.
-
-Next, like the abstract of a whitepaper, the reviewer will spend ~30 seconds
-reading the PR problem description. If what is described there doesn't look
-more important than competing issues, don't expect the reviewer to read on.
-
-Next, the reviewer will read the proposed changes. At this point, the reviewer
-needs to be convinced the proposed changes are a *good* solution to the problem
-described above.  If the proposed changes, not the code changes, generates
-discussion, consider closing the PR and returning with a design proposal
-instead.
-
-Finally, once the reviewer understands the problem and agrees with the approach
-to solving it, the reviewer will view the code changes. At this point, the
-reviewer is simply looking to see if the implementation actually implements
-what was proposed and if that implementation is maintainable. When a concise,
-readable test for each new code path is present, the reviewer can safely ignore
-the details of its implementation. When those tests are missing, expect to
-either lose engagement or get a pile of review comments as the reviewer
-attempts to consider every ambiguity in your implementation.
-
-### The PR Title
-
-The PR title should contain a brief summary of the change, from the perspective
-of the user. Examples of good titles:
-
-* Add rent to accounts
-* Fix out-of-memory error in validator
-* Clean up `process_message()` in runtime
-
-The conventions here are all the same as a good git commit title:
-
-* First word capitalized and in the imperative mood, not past tense ("add", not
-  "added")
-* No trailing period
-* What was done, whom it was done to, and in what context
-
-### The PR Problem Statement
-
-The git repo implements a product with various features. The problem statement
-should describe how the product is missing a feature, how a feature is
-incomplete, or how the implementation of a feature is somehow undesirable. If
-an issue being fixed already describes the problem, go ahead and copy-paste it.
-As mentioned above, reviewer time is scarce. Given a queue of PRs to review,
-the reviewer may ignore PRs that expect them to click through links to see if
-the PR warrants attention.
-
-### The Proposed Changes
-
-Typically the content under the "Proposed changes" section will be a bulleted
-list of steps taken to solve the problem. Oftentimes, the list is identical to
-the subject lines of the git commits contained in the PR. It's especially
-generous (and not expected) to rebase or reword commits such that each change
-matches the logical flow in your PR description.
+Add only code to the codebase that is ready to be deployed. If you are building a large
+library, consider developing it in a separate git repository. When it is ready to be
+integrated, the Solana maintainers will work with you to decide on a path forward. Smaller
+libraries may be copied in whereas very large ones may be pulled in with a package manager.

 ### When will my PR be reviewed?

-PRs are typically reviewed and merged in under 7 days. If your PR has been open
-for longer, it's a strong indicator that the reviewers aren't confident the
-change meets the quality standards of the codebase. You might consider closing
-it and coming back with smaller PRs and longer descriptions detailing what
-problem it solves and how it solves it. Old PRs will be marked stale and then
-closed automatically 7 days later.

+and longer descriptions detailing what problem it solves and how it solves it.

-### How to manage review feedback?
-
-After a reviewer provides feedback, you can quickly say "acknowledged, will
-fix" using a thumb's up emoji. If you're confident your fix is exactly as
-prescribed, add a reply "Fixed in COMMIT\_HASH" and mark the comment as
-resolved. If you're not sure, reply "Is this what you had in mind?
-COMMIT\_HASH" and if so, the reviewer will reply and mark the conversation as
-resolved. Marking conversations as resolved is an excellent way to engage more
-reviewers. Leaving conversations open may imply the PR is not yet ready for
-additional review.
-
-### When will my PR be re-reviewed?
-
-Recall that once your PR is opened, a notification is sent every time you push
-a commit.  After a reviewer adds feedback, they won't be checking on the status
-of that feedback after every new commit. Instead, directly mention the reviewer
-when you feel your PR is ready for another pass.

 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.
