This proposal has been implemented as a hard fork since block 49,1407 of the original Bitcoin blockchain.
Being a hard fork, it resulted in a new blockchain, named Bitcoin Gold (BTG).
A Complete Guide to Understanding This Blockchain Concept
The core idea behind this concept is to address the issue of mining centralization which has hurt the original Bitcoin idea of decentralized digital cash whereby more hash power has resulted in a power shift towards miners with more hashing power.
BTG uses the Equihash algorithm as its mining algorithm instead of PoW; hence it is inherently ASIC resistant and uses GPUs for mining.
There are other proposals like Bitcoin Next Generation, Solidus, Spectre, and SegWit2x which will be discussed later in , Scalability and Other Challenges, in the context of performance improvement in blockchain networks.
Why This Matters for Blockchain Technology
Understanding Bitcoin Gold is not just an academic exercise — it has real-world implications for how blockchain systems are designed, deployed, and secured. Whether you are a developer building decentralized applications, a business leader evaluating blockchain adoption, or a curious learner exploring the technology, this knowledge provides a critical foundation.
