The Story of Aryacoin’s dPoW Integration

This article was first published on Komodo

Aryacoin (AYA) successfully integrated Komodo’s delayed Proof of Work (dPoW) on April 16, 2020. Before dPoW integration, the project was the target of a major 51% attack

Since dPoW integration, the network has been able to continuously stop these attacks, restoring confidence in the project’s future and stopping a ~$1.23 million 51% attack along the way.

dPoW For 51% Attack Security

Komodo’s delayed Proof of Work (dPoW) security service works by recycling the enormous hash rate of the Bitcoin network through a series of cross-chain notarizations. This solution offers Bitcoin-level security to both Proof of Work and Proof of Stake chains. This creates a situation where, regardless of the network’s original mining difficulty, an attacker would need to overcome both the original network and Bitcoin’s network in order to pull off a 51% attack. 

For Komodo-based chains, the integration process is much simpler. In contrast, the integration process for Aryacoin was more resource-intensive and required a lot of custom work as it’s not a Komodo-based blockchain.

AYA Blockchain Security

Here’s a brief summary of why Aryacoin decided to integrate dPoW.

A major 51% attack was carried out against the Aryacoin network prior to dPoW integration. Because the AYA coin was listed on multiple exchanges and trading volumes were high, the attacker(s) were able to gain profits through double-spending. Even worse, they were selling AYA at very low prices in exchange for other assets. As a result, the price of AYA dipped to an all-time low of $0.000569 USD.

Although the network increased its mining power, this wasn’t an effective solution since it was possible for miners to rent power on NiceHash to gain control ...
