Build Status Go Report Card ISC License GoDoc

bsvd is a full node Bitcoin (BSV) implementation written in Go (golang).

This project is a port of the bchd codebase to Bitcoin (BSV). It provides a high powered and reliable blockchain server which makes it a suitable backend to serve blockchain data to lite clients and block explorers or to power your local wallet.

bsvd does not include any wallet functionality by design as it makes the codebase more modular and easy to maintain. The bsvwallet is a separate application that provides a secure Bitcoin (BSV) wallet that communicates with your running bsvd instance via the API.

Requirements

Go 1.9 or newer.

Install

Install Pre-built Packages

The easiest way to run the server is to download a pre-built binary. You can find binaries of our latest release for each operating system at the releases page.

Build from Source

If you prefer to install from source do the following:

  • Install Go according to the installation instructions here: http://golang.org/doc/install

  • Run the following commands to obtain btcd, all dependencies, and install it:

$ go get github.com/bitcoinsv/bsvd

This will download and compile bsvd and put it in your path.

If you are a bsvd contributor and would like to change the default config file (bsvd.conf), make any changes to sample-bsvd.conf and then run the following commands:

$ go-bindata sample-bsvd.conf  # requires github.com/go-bindata/go-bindata/
$ gofmt -s -w bindata.go

Getting Started

To start bsvd with default options just run:

$ ./bsvd

You'll find a large number of runtime options on the help menu. All of which can also be set in a config file. See the sample config file for an example of how to use it.

Docker

Building and running bsvd in docker is quite painless. To build the image:

docker build . -t bsvd

To run the image:

docker run bsvd

To run bsvctl and connect to your bsvd instance:

# Find the running bsvd container.
docker ps

# Exec bsvctl.
docker exec <container> bsvctl <command>

  • Increase MaxScriptElementSize in txscript package

    Increase MaxScriptElementSize in txscript package

    Recently, a transaction with 17kb of OP_RETURN data was mined by coingeek. https://blockchair.com/bitcoin-sv/address/d-3f5c7cbe8927da73271dba9c1bc1abb4

    If this is going to become a thing, txscript pkg will need updating. Not sure what the new limit will be if any.

    To test, I changed script.go line 46 from a value of 520, to 20520 MaxScriptElementSize = 20520 // Max bytes pushable to the stack.

    This was all that was required to generate a large tx. Not sure what is required for broadcasting, or what else would be effected as I'm using this for tx utils, not running a node.

  • increase maxscriptsize from 520 to 100000 bytes

    increase maxscriptsize from 520 to 100000 bytes

    refs #1

    There are a few things to consider with this:

    • txscript tests might need to be restructured a bit. They iterate a lot now, and take several orders of magnitude longer to complete.
    • There are test parameters in txscript/data/script_tests.json that would require very large string payloads to make them pass (one 'b' character per byte). Not sure how these should be handled.
    • The wire package also has a limit in const MaxFilterAddDataSize of 520 bytes in wire/msgfilteradd.go According to this: https://github.com/bitcoin/bips/blob/master/bip-0037.mediawiki the maximum payload size is 36,000 bytes, which is exceeded by this new limit.
    • Also some of the tests in wire seem to assume 3 bytes max for OP_PUSHDATA_2 instead of 5 for OP_PUSHDATA_4

    absurdly-high-fee Error

    My node is running but

    When i try to insert same data into the BSV node frequently then its giving me error "absurdly-high-fee Error"

    When i insert insert values in the node after some time interval it's working fine !

    What will be the issue ? can anyone please explain me ?
