This is a document highlighting the changes and updates made to Stacker News over time.

11/23/2022 - Sats Now Affect Ranking

The amount of sats tipped now affects the ranking of an item, in addition to the trust of the user tipping the item.

  • In an effort to make this feature sybil resistant, SN now takes 10% of tips which are distributed in daily rewards (like all other revenue)
  • Ranking is still influenced by a user's trust, which is only earned by voting for things other stackers deem to be good
  • Tipping an item with more sats amplifies your trust, giving a user more influence on an item's ranking
  • The relationship between sats contributed and the influence on ranking is not linear, it's logarithmic, i.e. sat whales have to spend exponentially more sats to have more influence than minnows

The effect a user's tip has on an item's ranking is trust*log10(total tip amount) where 10 sats = 1 vote, 100 sats = 2, 1000 sats = 3, and so on ... all values in between are valid as well.

When you view a post, now there's a little 'related' section showing similar posts.

In addition, now redirects to SN. Thanks to @02d0db813f for the recommendation.

10/25/2022 - Search Improvements

With the latest search improvement release, you can now:

  • Search for users
  • Constrain searches by URL
  • Constrain search by username

Additional changes include:

  • Top posts and comments can be ordered by sats and comments (in addition to votes)
  • Top users can be ordered by comment and post count (in addition to stacked and spent)
  • We now support the South African Rand in Currencies thanks to @ekzyis
  • The docker environment for dev now has a worker image thanks to @bitcoinplebdev

10/20/2022 - Search Filters

When you search you can now select:

  • What content you want to see: everything, just posts, and just comments
  • Sorted by: match, recent, sats, upvotes, number of comments
  • What timeframe: forever, last day, week, month, and year

10/4/2022 - Lightning Animations, Currency Conversion, & More
  • You can now toggle the lightning bolt animation whether you're logged in or not by clicking the lightning icon next to the dark mode icon in the footer
  • You can now choose your preferred fiat currency from a limited list in settings, which affects both your price in the navbar and when you post a job.
    • Thanks to @ekzyis who did this work.
  • When you click on the link icon of a heading in a post, it now copies the linked heading to your clipboard.
  • Scrollbars in the usernym navbar dropdown are fixed in Chrome.

9/29/2022 - Job Posting Fee Update
  • Jobs can now be posted for a flat cost of 1 sat, and the sats/min fee is optional.
  • Job posters can still choose to pay a sats/min fee to promote their job and have it ranked above the non-promoted jobs

9/27/2022 - Greeter Mode, Fee Updates, & User Bios
  • If you toggle on 'greeter mode' in settings, you will see free posts/comments created by new users. As a greeter, you are doing the community a service by screening new users. When you upvote their posts/comments, you make their posts and comments visible to non-greeters, and you give the new users sats to spend.
  • We've removed the fee multiplier on images and links. Conditional costs are more confusing than they're worth.
  • User bios will no longer appear on the homepage. They'll still appear in the recent tab, but will not create noise on the homepage.

9/21/2022 - Wild West Mode
  • On each item, there is now a ... link where you can tell us you don't like something. Think of this like a downvote. It costs one sat and is a vote to 'outlaw' an item. Items with low downvotes relative to upvotes are simply down ranked. However, if an item receives enough downvotes, they are outlawed and filtered from view.
  • If you toggle on "wild west mode" in settings, downvotes have no effect on your experience. It'll be like they don't exist. Downvoted posts don't lose ranking and are never outlawed. If you're not logged in, or haven't toggled WWM, by default you are in tenderfoot mode.

9/14/2022 - Rewards Refinements
  • From now on, rewards will now display where you got rewards from:
    • top posts
    • top comments
    • or upvoting top posts/comments

9/2/2022 - Various Refinements
  • You can now select to hide your invoice descriptions in your settings. This is useful if you want to not have your funding source associated with your SN identity.
  • You can now clear input fields, they have an ‘x’ if you want to clear them
  • User nyms autocomplete when you attempt to forward sats to another user on a post
  • Titles turn grey when you've already read a story, and visited links are more distinctly dull
  • The total earned sats of the comments of a post are now displayed at the top of the comment section. If you hover over the comments under the post title, it will also give you this number.
  • When there are new comments on a post you've read, it will display a “new” button under the post title. This only applies if you're viewing things on the same device/browser.
    • Thanks to @gmd for requesting this

8/18/2022 - Edit Button, Poll Updates, & Recent Comments
  • The edit button that appears after making a post now gives you the ability to edit:
    • your boost (by adding more)
    • the user you want to forward sats to
    • the ability to add images or links
    • the ability to add additional choices to a poll
  • If there are costs associated with the edits you also get receipts similar to the ones you get when posting/commenting.
  • Polls now also allow for up to 10 choices.
  • You can browse recent comments but there isn't a link anywhere to that yet. I just selfishly wanted to see where active discussions are going on.

  • New users no longer get free posts or comments as a spam prevention measure
  • Users can no longer add images as links. For example, [![alt](image)](link) will now just display the image
  • It now costs 10x more to add images or links to posts/comments. For example, if your discussion post costs 1 sat, it now costs 10 sats to add an images and/or link.
  • Repeated posts/comments and self-replies within a 10 minute window cost x10^X more, where X is the number of repeat posts or comments you've made in the last 10 minutes
  • When you pay more than 1 sat for a post or comment:
    • An "info" icon will appear, and when clicked it will show you a breakdown of your posting costs
    • The post/comment button will display the amount of sats you'll be paying

7/30/2022 - Polls
  • You can make polls now. Each poll costs 1 sat to create, and 1 sat to vote in a poll. All of the sats from poll creation and votes go to the Stacker News daily rewards pool.

7/7/2022 - Enhanced Trust Algorithm, Rewards, & Notifications
  • We've refined how trust is established between users. In this release, trust is gained when two users upvote the same piece of content and diminished when one user upvotes something the other user doesn't. A statistical model is used, specifically, a binomial proportion interval, to determine this trust level even when the sample size of upvotes is small.
  • Given the trust algorithm change, we needed to change daily rewards too, since your upvote trust doesn't entirely account for the value you bring to SN. Also, the way rewards were dispersed was not obviously related to the value you provided. You now receive rewards strictly depending on the last 36 hours of value you provided. Very good and active users are likely to see their daily rewards jump by 5-20x.
  • How rewards are dispersed now:
    • Users who posted the top posts of the last 36 hours get 1/3rd of the daily rewards. Users are rewarded based on how well the post ranked relative to the other top posts.
    • Users who posted the top comments of the last 36 hours get 1/3rd of the daily rewards. Users are rewarded based on how well their comment ranked relative to the other top comments.
    • Users who upvoted the top posts and comments above are given the last 1/3rd of daily revenue. Users are rewarded based on:
      • How early they upvoted the content relative other users
      • How much they tipped
      • Their upvote trust
      • The ranking of the content they upvoted
  • Reward notifications are always viewable in your notifications, and for users who don’t visit frequently we identify groups of reward notifications and combine them into one notification to limit noise.

6/10/2022 - Usage Dashboard
  • An MVP usage dashboard is now live. You can view it here. It's also available in the footer if you click analytics -> users. Site visitor data is still available via Plausible by clicking analytics -> visitors in the footer.

6/8/2022 - Linking Multiple Auth Methods
  • You're now able to link and unlink any authentication method we support to a single account. For example, you can link your Lightning wallet and your email to the same Stacker News account.
  • If an authentication method is already linked to another Stacker News account, you'll have to unlink that authentication method from the other account first or authentication will fail.
  • We also have new pinned post and notification bell icons.

5/18/2022 - Profile Photos, Comments, Notifications, and Lightning Address Upgrades
  • We have profile photos now. You can upload your own image in your profile settings.
  • Comment depth is now visually limited to 10 replies. You can still have longer discussions, but they will continue on other pages so they don’t disrupt the flow of comments on a given post.
  • You can now control the types of notifications you receive on your settings page
  • User profiles now display the user's lightning address. If you click on it, you'll see an LNURL-pay QR code to make a payment to that user.

3/18/2022 - Daily Earning Rewards
  • Daily earning is live. All the sats that SN has earned to date was paid back to the best users today, proportional to how well they are trusted.
  • In addition, the sats that Stacker News earns from ~jobs, posting fees, and boosts from here on will be divvied up daily, and sent back to SN's most trusted users. The idea is that the people who make the site valuable will be proportionally paid for their contributions.
  • Right now, we sum up all the sats we earn each day, then multiply it by how well a user is trusted relative to other users. That is, <daily sats earned> * <a user's trust>/<total trust of all users>.

2/28/2022 - The Jobs Sub is Live
  • The ~jobs sub is live. It's an MVP and it'll be refined over time. It's cheap to post a job: (10,000 sats/mo or $5) but as jobs are added, staying on the front page could cost more depending on what companies are willing to pay. Jobs are also paid for by the minute: 10,000 sats/mo is actually billed at 230 millisats/min.
  • The higher your bid the higher your job will rank. The minimum bid is 10000 sats/mo, but you can increase or decrease your bid at anytime. You can also edit or remove your job at anytime. Your job will be hidden if your wallet runs out of sats and can be unhidden by re-filling your wallet.

2/3/2022 - Web of Trust, Search, and Filter Upgrades
  • The Web of Trust is now the ranking mechanism we use on the homepage and in comments.
  • Search highlighting has been added to all queries, and exact matches rank higher.
  • We now show top spenders in the top tab.

  • Search is now live. You can search for anything on Stacker News by clicking the floating yellow icon in the bottom-right corner of your screen. This search addition is intentionally simple so we don’t have to overhaul the UI to support it.

1/21/2022 - Tips, Twitter Embed, & UX Upgrades
  • Tips have been overhauled. If your default tip amount is 10 sats, your first click of the lightning bolt gives the user 10 sats as do the subsequent ones. You can still hold the bolt to send a custom amount.
  • Hovering over the sat amount shows how many users have contributed sats to a post, and how much you have collectively contributed.
  • Twitter embeds are live, so now all Twitter links are rendered on Stacker News as embedded tweets.
  • Static assets (js/css) are now served from a global CDN to improve site performance.
  • Invite notifications are live, so you know when a new user has redeemed your invite code.
  • A number of addiitonal bug fixes have been completed too.

1/18/2022 - Web of Trust Algorithm is Live
  • The Web of Trust ranking algorithm is now live. You can view it at
  • Each user is a node in a graph and directed edges in the graph represent how much a user, Alice, trusts another user, Bob, on a scale of 0-0.9. We determine this edge value based on how many upvotes Alice has given Bob. We then use the model described in Modelling a Public-Key Infrastructure (1996) to assign each user a single trust score of 0-0.9 where the source node is the moderator of the sub. We compute these trust scores daily.
  • That trust score is then used to weight a user's upvote in the ranking algorithm. For instance if Alice has a trust score of 0.9 and Bob has a trust score of .45, Bob's upvotes count for half as much in ranking. Carol, who is a Sybil attacker created by Bob (and hasn't received any upvotes), has a trust score of 0 , and consequently their upvotes don't count at all.

1/7/2022 - Daily Discussion Thread & Various Updates
  • We have added a daily discussion thread. To find it, look for the pin icon on the main page.
  • We now save any un-submitted posts or comments to local storage, so if you accidentally navigate away from the page you won't lose your work.
  • When you post a new post it takes you to the 'recent' tab.
  • You can no longer see the wallet balances of other users.
  • We added a job queue as a backend upgrade. This will allow us to distribute a bunch of periodic tasks that shouldn't run alongside the web servers.

12/21/2021 - Sorting Comments & Bug Fixes
  • You can now sort comments: hot (default), recent, and top.
    • Thanks to @jack for recommending comment sorting on Github.
  • We have fixed dupe URL bugs and logout redirection errors
    • Thanks to @sgornick and @nout for reporting these issues on Github

12/16/2021 - Top Comments & Users
  • You can now view top comments and top users in addition to top posts.

12/16/2021 - Historical Transaction Data
  • You can now view your historical transaction data. If you're logged in and visit this link you can see all your wallet activity. There's a link to your “satistics” on both your profile and wallet pages.

12/13/2021 - Tipping Refinements
  • A few more tipping refinements have been released. There is no longer a half filled bolt after your first tip, everyone's tip default is now 1 sat, and the tip default can only be set to another amount in your settings.
  • I reset the log base of the color index on the Lightning bolt icons to 10,000 sats, many users suggested a 100,000 sat tip is too rare.

12/6/2021 Tipping Refinements & Lightning Bolt Colors
  • We revamped the upvote/tipping UI. We have a new upvote button and it works the same but changes its look based on how much you've tipped. One upvote gives you a half filled bolt, the bolt fills fully after you've given the OP 10 sats, and the bolt changes color the more sats you tip.
  • The color of the Lightning bolt icon is determined by taking the log base 100,000 of the amount of sats you've given the OP. For example, the bolt changes color a lot more at lower tip amounts and if you give the OP 100,000 sats your bolt will finally be purple.
  • Your own posts don't display the bolt next to them because you can't interact with them anyway. Plus, it gives you some visual indication of where your posts are.

11/28/2021 - Tipping Refinements
  • “Sats” and “tipped” amounts are now added together as just sats. You can still get the break down of how many users sent sats by hovering over “sats”.
  • We have a new tipping icon that should make tipping more obvious.
  • Clicking on reply notifications now take you to the root thread rather than the parent's thread.
  • Wallet balances and stacked sats abbreviate at 10k or more rather than 1k
  • The header/navbar is SSR'd so it doesn't load after the page does
  • We added a warning on user bios that their bio will be shared as a post

11/12/2021 - Various UX Improvements
  • I just shipped more compact feed, comments, and a few other very minor enhancements.

11/10/2021 - Dark Mode
  • We now have dark mode! You can toggle it in the footer. It will also respond to your OS preference if you have one set.

10/30/2021 - Tip Default Improvements
  • You can now reset your tip defaults in the settings page.
  • If you press and hold the tip button, it'll display the tip dialog so you can tip more or less than your default.

10/28/2021 - Comment Enhancements, LNURL, Dupe Detection & More
  • We have added some comment thread enhancements that saved collapse state and label the OP within the comments.
  • We have integrated LNURL-withdraw.
  • We have added URL dupe detection.
  • We have made notifications more concise
  • We have implemented a fix for tipping quickly after upvoting causing 1 sat boost

10/21/2021 - Post Filtering Improvements
  • You can now filter top posts by day, week, month, year, or forever! The "switch" for this is in the nav bar at the top and is also available in the dropdown. We also remember whether you last viewed "top" or "recent" and which "top" interval you last viewed so that it's fewer clicks away next time you visit.

10/20/2021 - Dev Environment Improvements
  • It was relatively complicated to get a local dev environment up and running so I was asked to dockerize it. I've updated the README on the repo but the important bits:
    • Install docker-compose and deps if you don't already have it installed
    • git clone sn && cd sn
    • docker-compose up --build
  • You should then be able to access the site at localhost:3000 and any changes you make will hot reload. If you want to login locally or use lnd you'll need to modify .env.sample appropriately.

10/15/2021 - Invite Faucets
  • Invite faucets are live. Users can now onboard another user with some sats when they set up an account with your invite code.

10/7/2021 - Lightning Address Support
  • We now support Lightning Addresses. In wallets that support sending to Lightning Addresses (I tested Breez and Wallet of Satoshi), you can now send sats to your SN wallet by sending to <username>, e.g.

9/30/2021 - Server-side Rendering
  • We've implemented server-side rendering for all the pages. You should no longer see "loading skeletons." This will make the site feel more performant.

9/24/2021 - User Bios
  • Users now have bios. Bios reuse some aspects of discussion posts internally. This allows for markdown bios and comments on a profile without having to implement anything new. This is also a way for users to introduce themselves to the community when they fill out their bio.

9/12/2021 - Tipping Refinements
  • Boost is no longer an "upvote option" and is now only set when creating a post
  • Tips are the only second upvote action. Default tip amounts can be set to avoid subsequent popups.

9/10/2021 - Tipping is Live
  • On your second upvote click, you now get a dialog to either boost or tip a post/comment. Tips go directly to the poster/commenter.
  • Boost, as before, goes to the site and just boosts the rank of the content. This should allow for more interesting incentives for participation until I implement more levers to pull on post economics.

9/7/2021 - Caching Improvements
  • We implemented some caching updates so the data you view on SN is now more likely to be up to date with the server. This should improve performance.

8/20/2021 - RSS Improvements, Spelling, and Notifications
  • We released some RSS feed improvements
  • We fixed the mis-spelling of ‘withdrawal’
  • We now highlight your new notifications in the /notifications area.

Oh wow, this is really useful. Thanks, and please continue updating this thread !

AMAZING progress with everything! I can only wish for a mobile app - I barely log in if I have to use my computer, and using the browser through the phone just isn't good enough

10 sats \ 0 replies \ @newnym 8 Oct

Very useful to know what changed when. Please keep doing this.

Wow this is amazing. Have some sats!

🤘Finally we get a change log
