Welcome to SophiaTX Developer Portal
This site is designed to aid those interested in developing applications on the SophiaTX blockchain.
If you don’t know about SophiaTX yet, visit sophiatx.com.
The code for this site is on github. If you’d like to see a specific improvement
you can either submit a pull request or file an issue.
Site Resources
The QUICKSTART section has some general information on working with nodes, existing testnets and building source code.
There is also a TUTORIALS section that provide a lot of useful information on different topics like creating custom plugins on top of core functionality of SophiaTX blockchain, etc…
Our SDK’s section will take you through the basics of interacting with SophiaTX apis in Javascript and C#.
More detailed API specs are available in the API’s section. Those apis are under development, so please read notes at the top of each section.
CLI_WALLET section provides information about tool for interfacing with sophiatxd.
SophiaTX Blockchain
SophiaTX is Delegated Proof of Stake blockchain. The source code is publicly available on github.
Public Announcement & Discussion
SophiaTX was announced on the Bitcointalk forum prior to the start of any mining.
Whitepaper
You can read the SophiaTX Whitepaper at SophiaTXWhitePaper.pdf.
Quickstart
Just want to get up and running quickly? We have pre-built docker images for your convenience. More details are in our technical quickstart guide.
Downloading
Latest release can be always found here
Building
If you would like to build from source, we do have build instructions for Linux (Ubuntu LTS).
Config File
Run sophiatxd once to generate a data directory and config file. The default location is witness_node_data_dir. Kill sophiatxd.
It won’t do anything without seed nodes. If you want to modify the config to your liking, we have two example configs.
( full node,
witness node )
All options will be present in the default config file and there may be more options needing to be changed from
those configs (some of the options actually used in images are configured via command line).
Seed Nodes
A list of some seed nodes to get you:
System Requirements
For a full web node, you need at least 50GB of disk space available.
SophiaTXd uses a memory mapped file which currently holds 26GB of data and by default is set to use up to 80GB.
The block log of the blockchain itself is a little over 1GB.
It’s highly recommended to run sophiatxd on a fast disk such as an SSD or by placing the shared memory files in a
ramdisk and using the --shared-file-dir=/path command line option to specify where.
At least 4GB of memory is required for a full web node. Seed nodes (p2p mode) can run with as little as 2GB of memory.
Any CPU with decent single core performance should be sufficient. SophiaTXd is constantly growing,
so you may find you need more disk space to run a full node. We are also constantly working on optimizing SophiaTX’s use of disk space.
Below are SophiaTX specific terms that will help you understand documentation, whitepapers, and the speech of SophiaTX.

Transactions
Dictionary of Transaction Terms
- Transaction
- Operations submitted to the blockchain
- Pending Transaction
- Transaction that is pending and to be included to the blockchain
- Transaction Hex
- Hash of the transaction
- Digest
- Hash (sha256) of the transaction used for signing
