Sparks (SPK)

Sparks is a standalone Proof-of-Work cryptocurrency with its own blockchain, not a token built on someone else's network. Like Bitcoin, it relies on miners rather than validators or staking. The key difference is that it's a much smaller, independent project with its own ecosystem centered around sparkspay.io.

Sparks uses Proof-of-Work, meaning miners compete to solve cryptographic puzzles, and whoever wins gets to add the next block of transactions. This makes the network's transaction history extremely hard to tamper with, since rewriting it would require redoing all the mining work. It's the same security model that has protected Bitcoin for over a decade.

New coins enter circulation purely through mining — there's no pre-mine-style central issuance you'd find with many modern tokens. Miners earn block rewards for securing the network, and the emission schedule is defined by the protocol itself. You can verify the current supply and reward structure directly on the blockchain explorer.

As a coin with its own blockchain, SPK needs a compatible wallet rather than a generic ERC-20-style one — check the official site at sparkspay.io for recommended options. Beyond holding, the project is oriented toward payments, hence the 'Pay' in its name. Always download wallets only from official sources to avoid fake apps.
