The new, performant, and simplified version of Holochain on Rust (sometimes called Holochain RSM for Refactored State Model)



Project Forum Chat

Twitter Follow License: License: CAL 1.0

This repository contains the core Holochain libraries and binaries.

This is the most recent and well maintained version of Holochain with a refactored state model (you may see references to it as Holochain RSM).

Code Status

This code is in alpha. It is not for production use. The code is guaranteed NOT secure.

We will be frequently and heavily restructuring code APIs and data chains until Beta.

We are currently only supporting Linux at this time. You may or may not be able to successfully build and run Holochain on macOS. You definitely won't be able to on Windows (unless you are using WSL, but even that is untested). We will definitely be rolling out support for these OSes in the future, but in the meantime please use Linux for development!

Making the Holochain binaries available in your shell

There are a number of contexts and purposes you might be running in which yield different ways to access binaries.

Using nix-shell on a local clone

Assuming you have installed the nix shell:

nix-shell --argstr flavor happDev

This nix-shell flavor installs wrapper binaries for holochain and hc that will automatically compile and run the binaries. This is very useful if you are tracking changes in the holochain repo because when you check out a new rev, running holochain will compile automatically to the version at that rev.

Building with cargo if you already have rust installed:

cargo install --path crates/holochain
cargo install --path crates/hc


$ holochain --help
    holochain [FLAGS] [OPTIONS]

    -h, --help           Prints help information
    -i, --interactive    Receive helpful prompts to create missing files and directories,
                             useful when running a conductor for the first time
    -V, --version        Prints version information

    -c, --config-path <config-path>
            Path to a YAML file containing conductor configuration

Running holochain requires a config file. You can generate one in the default configuration file locations using interactive mode:

$ holochain -i
There is no conductor config YAML file at the path specified (/home/eric/.config/holochain/conductor-config.yml)
Would you like to create a default config file at this location? [Y/n]
Conductor config written.
There is no database environment set at the path specified (/home/eric/.local/share/holochain/databases)
Would you like to create one now? [Y/n]
LMDB environment created.
Conductor ready.

As well as creating the config file this process also instantiates the initial LMDB database environment. If you provide a config file on first run with just the -c flag holochain will also initialize the environment even if not in interactive mode.

Development Environment

Assuming you have installed the nix shell:

git clone [email protected]:holochain/holochain.git
cd holochain

This will compile holochain and run all the tests.

If you get an error while running nix-shell about ngrok having an unfree license, you can fix that by running,

mkdir -p ~/.config/nixpkgs/
echo "{ allowUnfree = true; }" >> ~/.config/nixpkgs/config.nix

We have an all-in-one development environment including (among other things):

  • The correct version and sane environment variables of cargo/rust
  • Node for working with tryorama
  • Scaffolding, build and deployment scripts
  • Prebuilt binaries of core for various operating systems (soon)
  • Shared libs such as libsodium

It is called Holonix and you should use it.

It has plenty of documentation and functionality and can be used across Windows, Mac, and Linux. (Although Holochain itself currently only supports Linux.) It is based on the development tools provided by NixOS.

It is suitable for use in hackathons and 'serious' development for a long-term, production grade development team.

If you want to maintain your own development environment then we can only offer rough advice, because anything we say today could be out of date tomorrow:

  • Use a recent stable version of rust
  • Use node 12x+ for clientside work
  • Install any relevant shared libs like libsodium
  • Write your own scaffolding, build and development tools
  • Plan for dependency management as we ship new binaries

    Holochain <-> .Net / C# interface

    Update: initial sprinklings of a .net/C# conductor client are starting here:

    Hi Guys,

    Really happy Windows support has finally been added back in again, yay! :)

    But when I run cargo install holochain I get the follow error message:

  • Unable to install large apps

    Unable to install large apps

    The hard 16MB limit on websocket payload sizes has become a blocking error for me. The output from Tryorama in my tests looks like this (stack frames truncated):

    20:16:58 [tryorama: player c0] debug: initialized
    20:16:58 [tryorama: player c0] debug: Player.installHapps
    20:16:58 [tryorama: player c0] debug: Player.adminWs()

    20:17:13 [tryorama] error: Test error: 'Error: Timed out in 15000ms: register_dna\n'

    I have recently added a wasm-opt pass to my build to see if it alleviates the issue, but unfortunately the byte savings are modest (~25% shaved off).

    Suggest this be elevated as a serious issue as more complex applications continue to be developed. While my dna configs may appear to list a large number of zomes, I expect this will be nothing compared to highly modular app architectures being envisioned by and It is worth noting that the tests failing currently only involve 2 DNAs containing 19 zomes- the full hREA suite will be in excess of 15 DNAs and will also require several supporting auxilliary zomes in almost any useful configuration. And this does not factor in UI apps spanning multiple collaboration spaces, which may require access to multiple module suites simultaneously- leading to multipliers of 15-20 odd interrelated DNAs all being part of the same hApp bundle.

    To those pondering whether I might be able to reduce the filesize of things in other ways, I don't see this as a solution or even a long-term deferral of the problem.

    I suspect the issue will have to be solved mostly on the hc-utils side with the support of another API method or two from core, basically to chunk larger input files and send in pieces before reassembling on the other side.

    [BUG] [WASM metering?] Ribosome fails with `unreachable` in all sorts of fns when DNA gets exercised

    Describe the bug DNA works well at first, but at some point, after creating >100 entries, a zome call using hdk::chain::query returns this error:

    The code calling chain::query (perspective_diff_sync::revisions::current_revision) is this:

    pub fn current_revision() -> SocialContextResult<Option<HoloHash<holo_hash::hash_type::Action>>> {
        let app_entry = AppEntryType::new(4.into(), 0.into(), EntryVisibility::Private);
        let filter = ChainQueryFilter::new().entry_type(EntryType::App(app_entry)).include_entries(true);
        let mut refs = query(filter)?
            .map(|val| {
                    SocialContextError::InternalError("Expected element to contain app entry data"),
        refs.sort_by(|a, b| a.timestamp.partial_cmp(&b.timestamp).unwrap());
        Ok(refs.pop().map(|val| val.hash))

    The entry type we're filtering for consists of a hash and a timestamp:

    pub struct LocalHashReference {
        pub hash: HoloHash<holo_hash::hash_type::Action>,
        pub timestamp: DateTime<Utc>,

    Expected behavior chain::query() doesn't stop working when source chain gets filled with data.

    HDK v0.0.101 won't compile on MacOS. libsqlite3-sys can't compile for wasm32-unknown-unknown

    I've been working on an HDK wrapping rust crate, but I now realize it won't compile for the wasm target while building on MacOS, because of libsqlite3-sys sneaking in as a dependency, via hdk_derive -> holochain_zome_types -> holo_hash -> rusqlite -> libsqlite3-sys

    `local_network_tests::conductors_remote_gossip` and `local_network_tests::conductors_remote_boot_gossip` fail

    Hi! I've been experiencing gossip issues when going through a proxy server. This has happened to me both with the proxy at, and running my own with the current tip of develop.

    Investigating, I ran this and this tests, and they both fail.

    This is the result of running hc-merge-test in develop when unignoring those tests:

    test result: FAILED. 187 passed; 18 failed; 39 ignored; 0 measured; 0 filtered out; finished in 298.70s

    This is an example result of those failures:

    add list_public_keys to MetaLairClient


    The ultimate use case for this is to drive a user experience where a user gets to keep their old keys between hApp version migrations. At the moment, there's no good way to do this. The reason for that is that there's no way to just ask the keystore about the keys it has available within it, which means you can't tell whether it has any, or which ones might be usable for installation of a new hApp with. Necessary to add this function because the internals are all private at this level, which seems good.

    Once released, I will use this code over in lightningrodlabs/holochain-runner to provide that experience, but I do need this to be in place.

    @neonphog can you check this over?

    You can see here that I used to do this quite manually, and have the access that I needed: but it went away with the recent keystore update

    Softens the "rebuild-every-time" strategy for test_utils/wasm by directly parsing the Cargo.toml to discover upstream local deps. Downstream local changes no longer trigger a rebuild, making rapid iteration on e.g. holochain crate more rapider.

  • Improve compatibility of holochain types with Zome WASM, unify Timestamp type

    Improve compatibility of holochain types with Zome WASM, unify Timestamp type

    There are two implementations of the Timestamp; this merges them into one, and makes the Timestamp type available in WASM code. The now() method was moved from being an impl for Timestamp, eg. Timestamp::now(), to be a free-floating function in the crate, eg. timestamp::now(), so code changes are minimal and easy to understand. This improves the log output considerably, as Timestamps are always Debug-formatted as times, not as a pair of big numbers. Also, updated the fixt plumbing to actually create more-or-less "correct" random Timestamps for testing, so that conversion to Duration and SystemTime won't fail during tests that assume sane Timestamps for comparison.

    In addition, various holochain error types lacked some derive implementation, making it difficult to write Zome test code in rust (as Err types couldn't be compared).

    Finally, the holo_hash types and related functions were moved around a bit, to allow Zome code to build "wrappers" around all DHT times, allowing them to be De/Serialized as Strings for use over Zome API calls. This code is not included here, but used heavily in hash-heavy Zomes, such as the new holofuel implementation I'm working on...

    o Move Timestamp from holochain/types to zome_types o Give more ...Error types Debug, PartialEq, ... for Rust testing o Move some holo_hash types/impls around so they work in Zome code o Convert Timestamp::now() impl method to timestamp::now() function In order for Timestamp to be WASM compatible and usable in Zome code, we've moved it to holochain_wasm_types, and made the holochain_types timestamp now() a function, instead of a Timestamp::now() method. Minimal code change, vastly improved Zome coding experience. o Update base64 crate to avoid multiple inclusions
