Motivation
In order for Bitcoin SV apps to scale efficiently as traditional web services, apps must communicate directly with each other where possible and not rely on extra intermediaries.
Not all Bitcoin miners or transaction processors will maintain a full transaction index for public consumption. Some will instead opt to run so called "transaction pruning" nodes and instead specialize in other ways than offering data storage and indexing services.
TXQ decouples your application from miners and other Bitcoin service providers.
It's easy and extremely cost effective for services to simply index their own Bitcoin transactions and have the "single source of truth" be ready at hand and according to their backup needs.
TXQ makes it easy for developers to keep their entire application transaction history in their direct control or even on premise. At the same time, transaction sending is now "fire and forget" annd synchronization with miners happens automatically via Merchant API.

Why use TXQ?
TL;DR: Sending transactions is now "fire and forget". TLQ is a concurrent work queue that synchronizes transaction status with miners automatically — so you, the developer, do not have to worry it. TXQ complements your infrastructure and gives you full control over your apps slice of the BSV blockchain universe. Out-of-the-box you have your own TX and UTXO indexer for addresses, scripthashes, outpoints and spend indexes. Transaction processors (miners) now can focus on building and time-stamping blocks and leave it to apps to backup and own their own transaction data.
Up until now, Bitcoin SV "apps" relied on miners and blockchain cloudhosting services to get UTXO and transaction data. TXQ means app developers do not need to rely on 3rd parties for UTXO and transaction data — as long as all transactions of interest are saved to TXQ. That's it.
In order for Bitcoin SV applications to be able to scale as efficiently as traditional web services, the applications must be able to interoperate peer-to-peer and not rely on extra intermediaries.
To scale, Bitcoin applications must act more like peers and use the rawtx
format as the application data medium of exchange. Each service provider will maintain a copy of the rawtx
for all transactions in traditional storage and backed up to their policy.
TXQ abstracts the transaction settlement process with miners so developers focus on building and integrating your applications.
Features
Single Source of Truth
Provide your application and services with a consistent picture of it's "Bitcoin State" without relying on 3rd parties for lookups and indexing.
Automatically Sync with Miners (Merchant API)
Reliably broadcast transactions to a set of miners to get them reliably settled. Queue configuration options allow customizing the concurrency limit, exponential back off, and other behaviors.
All Merchant API requests are logged to the database and also streamed in real-time to the SSE event interface.
Self-Managed UTXO and Transaction Indexing
TXQ automatically stores and indexes UTXOs and transactions without relying on miners and cloud providers. Your businness always has transaction history and UTXOs ready-at-hand and can easily scale with no miner or vendor lock-in.
Publish and Subscribe Server Sent Events (SSE)
Easily connect TXQ with your other services via SSE sockets for subscribing to new transactions and events in real-time.

Server Sent Events (SSE)
Use EventSource to reliably receive updates.
The EventSource
automatically handles sending Last-EventId
as a header when the stream reconnects so you will always get any missed updates.
Example streams:
- Tx Inserts
- Tx Inserts (with Channel
- Tx Updates
- Tx Updates (with Channel)
- Merchant API Log
- Address Updates
- Scripthash Updates
New Transactions Stream (Default channel)
Stream all newly created inserts for the default queue channel

Merchant API Proxy (mapi)
Motivation
TXQ exposes a /mapi
endpoint proxy that allows clients to communicate with TXQ directly using the Merchant API.
TXQ automatically saves successfully broadcasted transactions under the default (empty) channel and then retries them as normal until they are settled or expired into the dead-letter queue.
Enable this in the configuration file with (default enabled):
merchantapi: {
...
enableProxy: true, // Exposes Merchant API proxy endpointts
...
}
Resources:
- Merchant API Documentation (MatterPool)
- BRFC Merchant API Specification (Official)
Storing channel
, metadata
, and tags
The Merchant API specification does not accept anything other than rawtx
for POST /mapi/tx
(push tx) therefore we leverage HTTP
headers to allow the client to specify channel
, metadata
, and tags
.
For example, set the following HTTP headers to attach additional information:
channel
: someChannelName
metadata
: {"description": "mydescription", "title": "a cool title"}
tags
: ["animals", "bitcoin"]
Query Primary Miner Merchant API
Use the first Merchant API endpoint for the request.
All events are logged to the database (enabled by default) under proxypushtx
, proxystatustx
and proxyfeequote
.
Transaction status examples:
GET /mapi/tx/10ad1739b568d2060831b91771d9b836e0f4efcb113d3a866732bbb9b8ca7ae2
Push transaction examples:
POST /mapi/tx
Fee quote examples:
GET /mapi/feeQuote
Query Specific Miner Merchant API
Select a specific miner to send the Merchant API request to. The identifer <miner-name>
must match the name in the configuration file.
All events are logged to the database (enabled by default) under proxypushtx
, proxystatustx
and proxyfeequote
.
Transaction status examples:
GET /merchantapi/taal.com/mapi/tx/10ad1739b568d2060831b91771d9b836e0f4efcb113d3a866732bbb9b8ca7ae2

Push transaction examples:
POST /merchantapi/taal.com/mapi/tx
POST /merchantapi/matterpool.io/mapi/tx
POST /merchantapi/mempool.io/mapi/tx
Fee quote examples:
GET /merchantapi/taal.com/mapi/feeQuote
GET /merchantapi/matterpool.io/mapi/feeQuote
GET /merchantapi/mempool.io/mapi/feeQuote
Query by Index of Miner Merchant API
Select a specific miner by index (ie: 0 is the first, 1 is the second, etc) to send the Merchant API request to. The identifer <miner-endpoint-index>
must match the name in the configuration file.
All events are logged to the database (enabled by default) under proxypushtx
, proxystatustx
and proxyfeequote
.
Transaction status examples:
GET /merchantapi/0/mapi/tx/10ad1739b568d2060831b91771d9b836e0f4efcb113d3a866732bbb9b8ca7ae2

POST /merchantapi/1/mapi/tx
POST /merchantapi/2/mapi/tx
Fee quote examples:
GET /merchantapi/0/mapi/feeQuote

Database Schema and Design
The database chosen is postgres because it provides important features for developers and enterprises:
- High performance relational database
- Excellent
jsonb
storage and custom indexes- Operating as high performance "NoSQL"
- Known scaling properties
- TimescaleDB provides a chronological partitioning
- Master-Slave replication
- ACID Compliant
Future work: Abstract away storage and allow developer to choose storage engine.
