What BitNode should I do?
=========================
.. warning :: This page contains spoilers regarding the game's story/plot-line.
After destroying their first :ref: `BitNode <gameplay_bitnodes>` , many players
wonder which BitNode they should tackle next. This guide hopefully helps answer
that question.
Overview of each BitNode
------------------------
BitNode-1: Source Genesis
^^^^^^^^^^^^^^^^^^^^^^^^^
Description
The first BitNode created by the Enders to imprison the minds of humans. It became
the prototype and testing-grounds for all of the BitNodes that followed.
This is the first BitNode that you play through. It has no special
modifications or mechanics.
Source-File
:Max Level: 3
This Source-File lets the player start with 32GB of RAM on his/her home computer when
entering a new BitNode, and also increases all of the player's multipliers by:
* Level 1: 16%
* Level 2: 24%
* Level 3: 28%
Difficulty
The easiest BitNode
BitNode-2: Rise of the Underworld
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
Description
Organized crime groups quickly filled the void of power left behind from the collapse of
Western government in the 2050s. As society and civlization broke down, people quickly
succumbed to the innate human impulse of evil and savagery. The organized crime
factions quickly rose to the top of the modern world.
In this BitNode:
* Your hacking level is reduced by 20%
* The growth rate and maximum amount of money available on servers are significantly decreased
* The amount of money gained from crimes and Infiltration is tripled
* Certain Factions (Slum Snakes, Tetrads, The Syndicate, The Dark Army, Speakers for the Dead,
NiteSec, The Black Hand) give the player the ability to form and manage their own gangs. These gangs
will earn the player money and reputation with the corresponding Faction
* Every Augmentation in the game will be available through the Factions listed above
* For every Faction NOT listed above, reputation gains are halved
* You will no longer gain passive reputation with Factions
Source-File
:Max Level: 3
This Source-File allows you to form gangs in other BitNodes once your karma decreases to a certain value.
It also increases the player's crime success rate, crime money, and charisma multipliers by:
* Level 1: 24%
* Level 2: 36%
* Level 3: 42%
Difficulty
Fairly easy, as hacking is still very profitable and the costs of various purchases/upgrades
is not increased. The gang mechanic may seem strange as its very different from anything
else, but it can be very powerful once you get the hang of it.
BitNode-3: Corporatocracy
^^^^^^^^^^^^^^^^^^^^^^^^^
Description
Our greatest illusion is that a healthy society can revolve around a
single-minded pursuit of wealth.
Sometime in the early 21st century economic and political globalization turned
the world into a corporatocracy, and it never looked back. Now, the privileged
elite will happily bankrupt their own countrymen, decimate their own community,
and evict their neighbors from houses in their desperate bid to increase their wealth.
In this BitNode you can create and manage your own corporation. Running a successful corporation
has the potential of generating massive profits. All other forms of income are reduced by 75%. Furthermore:
* The price and reputation cost of all Augmentations is tripled
* The starting and maximum amount of money on servers is reduced by 75%
* Server growth rate is reduced by 80%
* You now only need 75 favour with a faction in order to donate to it, rather than 150
Source-File
:Max Level: 3
This Source-File lets you create corporations on other BitNodes (although
some BitNodes will disable this mechanic). This Source-File also increases your
charisma and company salary multipliers by:
* Level 1: 8%
* Level 2: 12%
* Level 3: 14%
Difficulty
Somewhat-steep learning curve as you learn how to use and manage Corporations. Afterwards,
however, the BitNode is easy as Corporations can be very profitable.
BitNode-4: The Singularity
^^^^^^^^^^^^^^^^^^^^^^^^^^
Description
The Singularity has arrived. The human race is gone, replaced by artificially superintelligent
beings that are more machine than man.
In this BitNode, progressing is significantly harder:
* Experience gain rates for all stats are reduced.
* Most methods of earning money will now give significantly less.
In this BitNode you will gain access to a new set of Netscript Functions known as Singularity Functions.
These functions allow you to control most aspects of the game through scripts, including
working for factions/companies, purchasing/installing Augmentations, and creating programs.
Source-File
:Max Level: 3
This Source-File lets you access and use the Singularity Functions in other BitNodes.
2022-02-02 03:41:12 +01:00
Each level of this Source-File will reduce RAM costs.
2019-04-15 11:49:49 +02:00
Difficulty:
Depending on what Source-Files you have unlocked before attempting this BitNode,
it can range from easy to moderate.
BitNode-5: Artificial Intelligence
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
Description
They said it couldn't be done. They said the human brain,
along with its consciousness and intelligence, couldn't be replicated. They said the complexity
of the brain results from unpredictable, nonlinear interactions that couldn't be modeled
by 1's and 0's. They were wrong.
In this BitNode:
* The base security level of servers is doubled
* The starting money on servers is halved, but the maximum money remains the same
* Most methods of earning money now give significantly less
* Infiltration gives 50% more reputation and money
* Corporations have 50% lower valuations and are therefore less profitable
* Augmentations are more expensive
* Hacking experience gain rates are reduced
Source-File
:Max Level: 3
This Source-File grants you a special new stat called Intelligence.
Intelligence is unique because it is permanent and persistent (it never gets reset back to 1). However
gaining Intelligence experience is much slower than other stats, and it is also hidden (you won't know
when you gain experience and how much). Higher Intelligence levels will boost your production for many actions
in the game.
In addition, this Source-File will unlock the :js:func: `getBitNodeMultipliers()` Netscript function,
and will also raise all of your hacking-related multipliers by:
* Level 1: 8%
* Level 2: 12%
* Level 3: 14%
Difficulty
Depending on what Source-Files you have unlocked before attempting this BitNode, it
can range from easy to moderate.
BitNode-6: Bladeburners
^^^^^^^^^^^^^^^^^^^^^^^
Description
In the middle of the 21st century, OmniTek Incorporated began designing and manufacturing advanced synthetic
androids, or Synthoids for short. They achieved a major technological breakthrough in the sixth generation
of their Synthoid design, called MK-VI, by developing a hyperintelligent AI. Many argue that this was
the first sentient AI ever created. This resulted in Synthoid models that were stronger, faster, and more intelligent
than the humans that had created them.
In this BitNode you will be able to access the Bladeburner Division at the NSA, which provides
a new mechanic for progression. Furthermore:
* Hacking and Hacknet Nodes will be less profitable
* Your hacking level is reduced by 65%
* Hacking experience gain from scripts is reduced by 75%
* Corporations have 80% lower valuations and are therefore less profitable
* Working for companies is 50% less profitable
* Crimes and Infiltration are 25% less profitable
Source-File
:Max Level: 3
This Source-File allows you to access the NSA's Bladeburner Division in other
BitNodes. In addition, this Source-File will raise both the level and experience
gain rate of all your combat stats by:
* Level 1: 8%
* Level 2: 12%
* Level 3: 14%
Difficulty
Initially difficult due to the fact that hacking is no longer profitable and you have
to learn a new mechanic. After you get the hang of the Bladeburner mechanic, however,
it becomes moderately easy.
BitNode-7: Bladeburners 2079
^^^^^^^^^^^^^^^^^^^^^^^^^^^^
Description
In the middle of the 21st century, you were doing cutting-edge work at OmniTek Incorporated
as part of the AI design team for advanced synthetic androids, or Synthoids for short. You helped
achieve a major technological breakthrough in the sixth generation of the company's Synthoid
design, called MK-VI, by developing a hyperintelligent AI. Many argue that this was the first
sentient AI ever created. This resulted in Synthoid models that were stronger, faster,
and more intelligent than the humans that had created them.
In this BitNode you will be able to access the Bladeburner API, which allows you to access
Bladeburner functionality through Netscript. Furthermore:
* The rank you gain from Bladeburner contracts/operations is reduced by 40%
* Bladeburner skills cost twice as many skill points
* Augmentations are 3x more expensive
* Hacking and Hacknet Nodes will be significantly less profitable
* Your hacking level is reduced by 65%
* Hacking experience gain from scripts is reduced by 75%
* Corporations have 80% lower valuations and are therefore less profitable
* Working for companies is 50% less profitable
* Crimes and Infiltration are 25% less profitable
Source-File
:Max Level: 3
This Source-File allows you to access the Bladeburner Netscript API in other
BitNodes. In addition, this Source-File will increase all of your Bladeburner multipliers by:
* Level 1: 8%
* Level 2: 12%
* Level 3: 14%
Difficulty
Slightly more difficult than BitNode-6. However, you will be able to automate more
aspects of the Bladeburner feature, which means it will be more passive.
BitNode-8: Ghost of Wall Street
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
Description
You are trying to make a name for yourself as an up-and-coming hedge fund manager on Wall Street.
In this BitNode:
* You start with $250 million
* The only way to earn money is by trading on the stock market
* You start with a WSE membership and access to the TIX API
* You are able to short stocks and place different types of orders (limit/stop)
* You can immediately donate to factions to gain reputation
Source-File
:Max Level: 3
This Source-File grants the following benefits:
* Level 1: Permanent access to WSE and TIX API
* Level 2: Ability to short stocks in other BitNodes
* Level 3: Ability to use limit/stop orders in other BitNodes
This Source-File also increases your hacking growth multipliers by:
* Level 1: 12%
* Level 2: 18%
* Level 3: 21%
Difficulty
Very difficult until you unlock the Four Sigma (4S) Market Data API. After you
unlock the API however, it becomes moderately easy.
BitNode-9: Hacktocracy
^^^^^^^^^^^^^^^^^^^^^^
Description
When Fulcrum Technologies released their open-source Linux distro Chapeau, it quickly
became the OS of choice for the underground hacking community. Chapeau became especially
notorious for powering the Hacknet, a global, decentralized network used for nefarious
purposes. Fulcrum quickly abandoned the project and dissociated themselves from it.
This BitNode unlocks the Hacknet Server, an upgraded version of the Hacknet Node. Hacknet Servers generate
hashes, which can be spent on a variety of different upgrades.
In this BitNode:
2021-04-20 03:26:51 +02:00
2019-04-15 11:49:49 +02:00
* Your stats are significantly decreased
* You cannnot purchase additional servers
* Hacking is significantly less profitable
Source-File
:Max Level: 3
This Source-File grants the following benefits:
* Level 1: Permanently unlocks the Hacknet Server in other BitNodes
* Level 2: You start with 128GB of RAM on your home computer when entering a new BitNode
* Level 3: Grants a highly-upgraded Hacknet Server when entering a new BitNode
(Note that the Level 3 effect of this Source-File only applies when entering a new BitNode, NOT
2021-04-29 02:07:26 +02:00
when installing Augmentations.)
2019-04-15 11:49:49 +02:00
Difficulty

BitNode-10: Digital Carbon
^^^^^^^^^^^^^^^^^^^^^^^^^^
Description
In 2084, VitaLife unveiled to the world the Persona Core, a technology that allowed people
to digitize their consciousness. Their consciousness could then be transferred into Synthoids
or other bodies by trasmitting the digitized data. Human bodies became nothing more than 'sleeves'
for the human consciousness. Mankind had finally achieved immortality - at least for those
that could afford it.
This BitNode unlocks Sleeve technology. Sleeve technology allows you to:
1. Re-sleeve: Purchase and transfer your consciousness into a new body
2. Duplicate Sleeves: Duplicate your consciousness into Synthoids, allowing you to perform different tasks synchronously
In this BitNode:
2021-04-20 03:26:51 +02:00
2019-04-15 11:49:49 +02:00
* Your stats are significantly decreased
* All methods of gaining money are half as profitable (except Stock Market)
* Purchased servers are more expensive, have less max RAM, and a lower maximum limit
* Augmentations are 5x as expensive and require twice as much reputation
Source-File
:Max Level: 3
This Source-File unlocks Sleeve technology in other BitNodes.
2021-05-08 03:24:16 +02:00
Each level of this Source-File also grants you a Duplicate Sleeve.

Difficulty
Hard
BitNode-11: The Big Crash
^^^^^^^^^^^^^^^^^^^^^^^^^
Description
The 2050s was defined by the massive amounts of violent civil unrest and anarchic rebellion that rose all around the world. It was this period
of disorder that eventually lead to the governmental reformation of many global superpowers, most notably
the USA and China. But just as the world was slowly beginning to recover from these dark times, financial catastrophe hit.
In many countries, the high cost of trying to deal with the civil disorder bankrupted the governments. In all of this chaos and confusion, hackers
were able to steal billions of dollars from the world's largest electronic banks, prompting an international banking crisis as
governments were unable to bail out insolvent banks. Now, the world is slowly crumbling in the middle of the biggest economic crisis of all time.
In this BitNode:
* Your hacking stat and experience gain are halved
* The starting and maximum amount of money available on servers is significantly decreased
* The growth rate of servers is significantly reduced
* Weakening a server is twice as effective
* Company wages are decreased by 50%
* Corporation valuations are 99% lower and are therefore significantly less profitable
* Hacknet Node production is significantly decreased
* Crime and Infiltration are more lucrative
* Augmentations are twice as expensive
Source-File
:Max Level: 3
Destroying this BitNode will give you Source-File 11, or if you already have this Source-File it will
upgrade its level up to a maximum of 3. This Source-File makes it so that company favor increases BOTH
the player's salary and reputation gain rate at that company by 1% per favor (rather than just the reputation gain).
This Source-File also increases the player's company salary and reputation gain multipliers by:
* Level 1: 32%
* Level 2: 48%
* Level 3: 56%
Difficulty
Hard
BitNode-12: The Recursion
^^^^^^^^^^^^^^^^^^^^^^^^^
Description
Every time this BitNode is destroyed, it becomes slightly harder.
Source-File
:Max Level: Infinity
2021-05-03 22:02:26 +02:00
Each level of Source-File 12 will let you start with Neuroflux Governor
equal to the level of this Source-File.
This BitNode is meant to be done passively or when waiting for new content.
2019-04-15 11:49:49 +02:00
Difficulty
Initially very easy, but then it (obviously) becomes harder as you continue to do it.
Recommended BitNodes
--------------------
As a player, you are not forced to tackle the BitNodes in any particular order. You are
free to choose whichever ones you want. The "best" order can vary between players,
depending on what you like to do any what kind of player you are. In general, here
are the recommended BitNodes for different things:
For fast progression
^^^^^^^^^^^^^^^^^^^^
.. note :: This does not recommend the absolute fastest path, as I don't know what
exactly the fastest path is. But it does recommend the BitNodes that are
commonly considered to be optimal by players.
1. Repeat **BitNode-1: Source Genesis** until you max out its Source-File. Its Source-File
is extremely powerful, as it raises all multipliers by a significant amount.
2021-05-03 22:02:26 +02:00
2. Do **BitNode-5: Artificial Intelligence** once or twice. The intelligence stat it unlocks
2019-04-15 11:49:49 +02:00
will gradually build up as you continue to play the game, and will be helpful
in the future. The Source-File also provides hacking multipliers, which are
strong because hacking is typically one of the best ways of earning money.
2021-05-03 22:02:26 +02:00
3. (Optional) Consider doing **BitNode-4: The Singularity** . Its Source-File does not directly make you
2021-11-18 01:56:17 +01:00
more powerful in any way, but it does unlock the `Singularity API <https://github.com/danielyxie/bitburner/blob/dev/markdown/bitburner.singularity.md> `_ which
2019-04-15 11:49:49 +02:00
let you automate significantly more aspects of the game.
2021-05-03 22:02:26 +02:00
4. Do **BitNode-3: Corporatocracy** once to unlock the Corporation mechanic. This mechanic
2019-04-15 11:49:49 +02:00
has high profit potential.
2021-05-03 22:02:26 +02:00
5. Do **BitNode-6: Bladeburners** once to unlock the Bladeburners mechanic. The Bladeburner
2019-04-15 11:49:49 +02:00
mechanic is useful for some of the future BitNodes (such as 9 and 10).
2021-05-03 22:02:26 +02:00
6. Do **BitNode-9: Hacktocracy** to unlock the Hacknet Server mechanic. You can
2019-04-15 11:49:49 +02:00
consider repeating it as well, as its Level 2 and 3 effects are pretty helpful as well.
.. todo :: To be continued as more BitNodes get added
For the strongest Source-Files
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
Note that the strongest Source-Files are typically rewarded by the hardest BitNodes.
The strongest Source-File is that from **BitNode-1: Source Genesis** , as it raises
all multipliers by a significant amount.
Similarly, the Source-File from **BitNode-12: The Recursion** is also very strong
because it raises all multipliers. Each level of Source-File 12 is fairly weak,
but its effectiveness gets better over time since the effects of Source-Files and
Augmentations are multiplicative with each other.
The Source-File from **BitNode-9: Hacktocracy** is good because it unlocks the Hacknet
Server mechanic. The Hacknet Server mechanic causes Hacknet Nodes to produce a new
currency called *hashes* , rather than money. *Hashes* can be spent on powerful upgrades
that benefit your hacking, Corporation, Bladeburner, etc.
The Duplicate Sleeves granted by the Source-File from **BitNode-10: Digital Carbon**
are strong, but only after you have several of them and have spent some time/money upgrading
them.
For more scripting/hacking
^^^^^^^^^^^^^^^^^^^^^^^^^^
2021-11-18 01:56:17 +01:00
**BitNode-4: The Singularity** unlocks the `Singularity API <https://github.com/danielyxie/bitburner/blob/dev/markdown/bitburner.singularity.md> `_ , which
2019-04-15 11:49:49 +02:00
can be used to automate many different aspects of the game, including working for factions/companies,
purchasing & installing Augmentations, and creating programs
**BitNode-6** and **BitNode-7** unlock Bladeburner and its corresponding
2021-11-18 01:56:17 +01:00
`Netscript API <https://github.com/danielyxie/bitburner/blob/dev/markdown/bitburner.bladeburner.md> `_ . This allows you to automate an entire
2019-04-15 11:49:49 +02:00
new mechanic.
**BitNode-2: Rise of the Underworld** also unlocks a new mechanic and Netscript API for automating
it (the Gang mechanic). However, it is not as interesting as Bladeburner (in my opinion)
**BitNode-9: Hacktocracy** unlocks the Hacknet Server mechanic and several new
functions in the :ref: `Hacknet Node API <netscript_hacknetnodeapi>` for using it.
For new mechanics
^^^^^^^^^^^^^^^^^
**BitNode-2: Rise of the Underworld** unlocks a new mechanic in which you can
manage a gang. Gangs earn you money and can be very profitable once they get large
and powerful. The biggest benefit of gangs, however, is that they make all
Augmentations available to you through their corresponding faction.
**BitNode-3: Corporatocracy** unlocks a new mechanic in which you can manage a
corporation. You can earn money through Corporations by selling your stocks, or by
configuring your corporation to pay dividends to shareholders. If your Corporation
gets big enough, it can also bribe factions in exchange for faction reputation.
**BitNode-6: Bladeburners** unlocks a new mechanic that centers around combat rather
than hacking. The main benefit of the Bladeburner mechanic is that it offers a new
method of destroying a BitNode.
**BitNode-9: Hacktocracy** unlocks the Hacknet Server, which is an upgraded version of a
Hacknet Node. The Hacknet Server generates a computational unit called a *hash* . *Hashes*
can be spent on a variety of different upgrades that can benefit your hacking,
Corporation, Bladeburner progress, and more. It transforms the Hacknet Node from a
simple money-generator to a more interesting mechanic.
**BitNode-10: Digital Carbon** unlocks two new mechanics: Re-Sleeving and
Duplicate Sleeves.
For a Challenge
^^^^^^^^^^^^^^^
In general, the higher BitNodes are more difficult than the lower ones.
**BitNode-12: The Recursion** is an obvious exception as it gets progressively harder.
**BitNode-8: Ghost of Wall Street** provides a unique challenge as the only method
of earning money in that BitNode is through trading at the stock market.
