A journey into the hidden world of little sparks

TOKI & Bloki™
The Hidden World of Little Sparks

A warm children’s book about friendship, safety, and a mysterious world made of glowing paths, blocks and sparks — inspired by blockchain, tokens, wallets & gas, but told like a fairy tale.

Spark Valley – a fantasy world of glowing paths – by Markus Goffin
Spark Valley

The story takes place in Spark Valley, a fantasy world of glowing paths (blockchain), tiny drops of energy (Toki), safe little houses (wallets), and sparkling roads powered by Gasi (gas fees).

The world

Spark Valley

Deep inside a glowing world where paths of light appear and never get lost, Spark Valley watches over everything. Here, tiny sparks are born and become Tokis — each with a task, a purpose, and a home.

As you scroll, you’ll dive deeper: into glowing paths, blocks, sparks, and a house full of doors — a playful way to understand blockchain & more.

Toki – a small glowing drop of energy – by Markus Goffin
Toki
The little drop – the token

Toki is a small, glowing drop of energy. He stands for a token — something unique that can carry value or information. Still a little wobbly, but full of curiosity.

Bloki – a stable, friendly block with warm light inside – by Markus Goffin
Bloki
The block – safety

Bloki is a stable, friendly block with warm light inside. Everything that happens is kept with him — so it can’t simply be changed. He stands for blockchain security and trust.

Gasi – a lively, fast little spark that sprays sparks while running – by Markus Goffin
Gasi
The speedy spark – gas

Gasi is a lively spark who keeps hopping around. He helps Toki move along the glowing paths. Every move costs Gasi energy — that’s how the book playfully explains transaction fees (gas).

Walleta – a clever house with many doors and drawers – by Markus Goffin
Walleta
The house – the wallet

Walleta is a clever, warm house with many doors and drawers. Some are open, some are tightly locked. She stands for a wallet — a safe place where Tokis are kept.

Learning along the way

Blockchain made simple — for kids & grown-ups

As you scroll, short child-friendly explanations appear: What is a token? Why do we need a blockchain? Why does moving cost gas? And why is a safe home — a wallet — so important?

The texts are designed so children can dive in — while adults can still recognize the technology behind it.

Token (Toki)

A token is like a little spark with meaning — it can represent something: a star, a ticket, a story, or even a bit of value.

Blockchain (Bloki)

When many blocks line up, they form a chain where everything is recorded. That way everyone can check what happened.

Wallet (Walleta)

A wallet is a safe home for Tokis. Only the person with the right key can visit it or travel with them.

Gas (Gasi)

Every move costs energy — like a little spark-runner who clears the way for Tokis. When more is happening, Gasi has to work harder.
