The intersection of blockchain technology with real-world applications remains at the forefront of contemporary technological discourse. We will explore a unique synthesis of the Hive blockchain with an automatic cat feeder system, drawing attention to the implications and intricacies of such a union. This is my response to the request of @guiltyparties to make a built/designed and also include the code on the github for anyone to use if they are interested.
I. Introduction
Blockchain technology, historically relegated to the domain of digital transactions, has begun permeating diverse sectors. A case in point is the integration of Hive — a decentralized blockchain protocol — with a tangible mechanism designed for feeding stray cats. The primary purpose of this initiative was to utilize technology to effect real-world change based on blockchain interactions.
II. System Design and Overview
A. Hardware Configuration
The apparatus deployed for this project was centered around an Arduino microcontroller, supplemented by three auxiliary cameras. These cameras provided real-time streaming capabilities on Twitch, visually chronicling each feeding transaction.
B. Software Implementation
Leveraging JavaScript as the primary coding language, the system was integrated with the Hive blockchain using the hive-js library. A snapshot of the code demonstrates the methodology:
// ... [beginning of the code]
const hive = require("@hiveio/hive-js");
// ... [other code imports]
hive.api.setOptions({ url: RPC_URL });
function handler() {
console.log('move complete')
}
// ... [other functions]
board.on("ready", function() {
// ... [setup code]
setInterval(function () {
hive.api.getDynamicGlobalProperties(function (err, result) {
// ... [code handling block numbers]
});
}, GLOBAL_GET_INTERVAL);
setInterval(function () {
// ... [code checking for transactions]
if (isTransferTx && isTransferToAccount) {
// ... [code reacting to the transactions]
}
}, BLOCK_GET_INTERVAL);
});
Herein, each transaction in the Hive blockchain was monitored, specifically seeking those dispatched to a designated account ('east.autovote'). Upon identification, a signal would be dispatched to the Arduino, actuating the release mechanism to dispense food.
My brother @eastmael made this code on Github https://github.com/eastmaels/hive-arduino
III. Challenges and Learnings
One cannot underscore the complexities that arose from this synthesis. Foremost was the issue of maintenance. Given its outdoor placement, the apparatus was subjected to the elements, with summer temperatures posing notable operational challenges. These physical hurdles, juxtaposed with the digital sophistication of blockchain, underscored the multifaceted challenges inherent in integrating the ethereal with the tangible.
However, on a metacognitive level, the project illuminated the Hive blockchain's elasticity as an understructure, confirming its adaptability across diverse applications.
IV. Community Reception and Future Implications
The Hive community's response served as a testament to the potential of such integrations. This initiative morphed into a confluence for technologists and feline aficionados alike, emphasizing the impact of blockchain beyond mere digital transactions.
While this particular project has culminated, it beckons the question: How might future endeavors be optimized for durability without compromising their innovative essence? It serves as a compelling prologue to the potential fusion of tangible systems with the blockchain realm.
V. Conclusion
The narrative of the Hive-integrated cat feeder is emblematic of the expansive horizon of blockchain technology. By bridging the chasm between the digital and physical realms, it poses pivotal questions for future innovators: In what other avenues can blockchain be untapped.
