ZooBC - Advancing Blockchain Technology

Roberto Capodieci

I am rebuilding ZooBC from the ground up.

We are still at the dawn of the decentralization of information. Blockchain should never have been limited to finance alone, yet most existing systems are built almost exclusively around money, speculation, and shortcuts. When used outside that narrow scope, they often expose architectural weaknesses, security compromises, or performance limits that make them unsuitable for real-world applications.

After years of designing and implementing decentralized systems at Blockchain Zoo, and after living through both success and failure, my vision has matured. ZooBC is not a reaction to trends, it is the result of years of thinking, building, breaking, and learning. The original version taught hard lessons about assumptions, operations, incentives, and execution. Those lessons are now embedded into every design choice.

Today, ZooBC is being rebuilt by me alone, with full control over the architecture, code, and direction. This new version is not slower, it is faster, leaner, and significantly more efficient. ZooBC is now written in C++, allowing for tighter control over memory, execution, and performance, and enabling a level of efficiency that was not realistically achievable in the previous Go-based implementation.

ZooBC aims to become a general-purpose decentralized protocol designed as a decentralized application layer. Its core goal is to offer a platform for building web applications that are free from centralized control, resistant to censorship, secure by design, and capable of operating at real-world scale. Identity, data, logic, and interactions should not depend on a single company, server, or jurisdiction, and ZooBC is designed with that principle at its core.

This is not a reboot driven by hype or pressure. It is the result of a long maturation process and a renewed sense of clarity. Something genuinely new is being built here, informed by experience, sharpened by failure, and driven by the belief that decentralized technology can, and should, do much better.

Want to understand how a Layer 1 blockchain is built from scratch? The Blockchain Zoo Academy offers courses that walk you through every component of ZooBC's architecture.

Below are some of the core concepts and features currently being implemented:

ZooBC is being rebuilt. In public.

ZooBC is currently under active development. After the first implementation cycle between 2019 and 2021, the project is now being rebuilt from scratch with a refined vision, modern tooling, and hard-earned experience.

The new ZooBC core is written in C++, focusing on performance, efficiency, and long-term stability. The goal is not to release quickly, but to build a decentralized application layer that can realistically support web applications free from centralized control.

Development updates, architectural decisions, and technical progress are documented openly. This is not a marketing-driven project, but an engineering-driven one.

ZooBC IMPLEMENTATION TIMELINE

where we are now

×

Intro

ZooBC is not backed by a large, fixed team today and that is by design. The team behind ZooBC is meant to grow together with the protocol itself, step by step, as the project earns attention, trust, and real-world relevance.

The first incarnation of ZooBC was developed between 2019 and 2021 at Blockchain Zoo. During that period, a team of 27 developers worked primarily in Go Lang on what was, at the time, a full Layer 1 blockchain implementation. That work resulted in a complete protocol, core node software, wallet applications, a block explorer, and extensive documentation. The technical foundations, architectural decisions, and many of the concepts behind ZooBC are documented in the book available at https://bcz.bz/vol1.

Despite strong technical progress, the project ultimately failed to launch in 2021. The reasons were not technological, but operational and structural. The assumption that early node operators would be able to independently run and maintain infrastructure proved wrong, forcing centralization where decentralization was essential. Timelines slipped, costs increased, and the burden of personally funding development during the pandemic became unsustainable. By mid-2021, the project had to stop, unfinished, despite being close to launch.

In June 2025, ZooBC was restarted from scratch, with a different mindset and a different execution strategy. Today, ZooBC is being written entirely in C++, coded directly by its original architect. Development progress, design choices, and technical updates are documented publicly at https://zoobc.blog. This reboot is intentionally slower, more controlled, and focused on correctness, resilience, and long-term sustainability rather than speed or hype.

As ZooBC starts to attract renewed interest, the right people will naturally join the project. Architects, developers, researchers, communicators, and builders who understand both the technical depth and the hard lessons learned will have a place here. The team is not predefined; it will be shaped by the evolution of the protocol itself.

If you are interested in contributing to ZooBC and believe you can add real value, you are invited to get in touch directly at roberto@capodieci.com.

For those who want to deeply understand how ZooBC works and learn to build Layer 1 blockchains, the Blockchain Zoo Academy provides structured courses covering every aspect of blockchain development.

The Builder of Systems

Turns ideals into working infrastructure

Founder, Protocol and Product Architect

Not "the CEO type," nor "the lead dev." The Builder of Systems is the person who sees the whole machine, from philosophy to protocol to product, and makes it coherent. This is someone who thinks in architectures, incentives, governance, threat models, and real-world constraints. Someone who can move from first principles, freedom, ownership, censorship resistance, to an implementable spec, then to shipping priorities, without ever losing the core.

The Builder of Systems does not chase trends. This is a person who builds foundations. Someone who cares about elegance, correctness, and long-term survivability. It is a rare mix of technical depth, product intuition, and the stubborn patience required to carry a project for years before anyone applauds.

This person defines and protects the non-negotiables: principles, invariants, red lines, and what the project will never compromise on. The full system is their domain: protocol boundaries, modules, roles of nodes, incentives, governance, and upgrade paths. Vision becomes execution through specs, milestones, interfaces, and a clear sense of what gets built first and why. When design, community, UX, AI, and hardware pull in different directions, the Builder of Systems is the reference point that keeps the team aligned. Hard calls are made early: trade-offs, risk management, security posture, and what must stay simple even if it hurts.

This is not a hype machine. Not a manager of employees. Not a "move fast and break things" founder. Not someone who delegates the thinking.

Every great open source movement needs builders. But the ones that last have an architect who can hold the entire system in their head and keep it honest over time. The project stays meaningful because this person keeps the mission executable.

The Builder of Systems has built or architected distributed systems or protocols. Security and incentives are treated as engineering, not marketing. Specs and diagrams are written with the precision that engineers actually follow. And there is a strong personal "why": an inability to unsee what centralization is doing, and a refusal to accept it as inevitable.

The Voice

Makes the complex feel clear

Charismatic Native English Spokesperson

There is a particular kind of person who walks into a room full of hostile journalists, skeptical investors, or confused regulators, and walks out with all of them nodding. Not because they were charmed. Because they understood.

The Voice is that person. Someone who takes ideas that are deeply technical, politically sensitive, or philosophically complex, and makes them clear. Not dumbed down. Clear. Hype is absent, because hype is the tool of people who do not understand what they are selling. Jargon is absent, because jargon is the tool of people who are afraid of being understood.

This is a native English speaker, because nuance in this language matters and it cannot be faked. Media-ready not because of media training, but because of a natural calm, precision, and humanity under pressure. People trust the Voice not because trust is performed. It is simply there.

This person has probably done this before in some capacity. Maybe for a startup, a foundation, a movement. And probably stopped because the thing being represented stopped being worth representing.

This is not a PR hire. This is a founding member. Someone with a seat at the table, a stake in the mission, and the freedom to say what is true. The right person will not just represent the project. They will elevate it.

The Voice is one in a million: the rare communicator who combines absolute clarity with absolute conviction, and who has been waiting for something genuinely worth standing behind.

The Signal

A voice people trust because it was earned

Tech Influencer with Integrity

The Signal has an audience. Maybe tens of thousands, maybe millions. People listen when this person speaks about technology because that trust was earned the hard way: by being right more often than not, by refusing to shill garbage, and by explaining things honestly even when the honest answer was not popular.

Sponsorships have been turned down because the product was not good enough. Takes have been published that cost followers because accuracy mattered more than being liked. The Signal understands that influence is not a business model. It is a responsibility.

And there is probably a little frustration. Because the algorithms reward outrage, not insight. They reward frequency, not depth. And the more the game is played, the harder it becomes to recognize the person in the mirror.

This is someone who already has a voice and wants to use it for something that genuinely matters. The project is open source. The mission is about decentralization, freedom of expression, and putting power back where it belongs. The kind of thing the Signal has been talking about for years, except this one is actually being built.

The role is not marketing. It is not "content creation." It is being the bridge between a deeply technical project and the millions of people who need to understand why it matters. A founding voice, with a seat at the table and a name on the foundation.

The Signal is one in a million: a tech voice that people trust because it was earned, not bought, and who is ready to put that trust behind something permanent.

The Mind

Dreams of decentralized intelligence

AI Expert and Visionary

The Mind has spent years inside AI. Not using it. Inside it. This is someone who understands how models are trained, why they hallucinate, what attention mechanisms actually do, and why scaling laws work until they do not. Someone who could rebuild a transformer from scratch on a whiteboard, and probably has.

And this person is worried. Not about the sci-fi scenarios. Not about robots taking over. About something much more immediate and much more real: that the most powerful technology humanity has ever created is being concentrated in the hands of five, maybe six companies. That every "open source" release comes with strings attached. That the word "open" has become a marketing term for "we will let you look, but we will never let you leave."

The Mind has thought about what a truly decentralized AI would look like. Not a single massive model owned by a corporation and rented out through an API. Something fundamentally different. A network of small, independent, specialized models, each one sovereign, each one owned by the person running it, connected in a peer-to-peer mesh that behaves like the synapses of a collective brain. No central server. No kill switch. No single entity that can decide what the network is allowed to think.

This is not a prompt engineer. Not someone who fine-tunes models as a party trick. This is someone who understands AI from the silicon up. Someone who can look at a training pipeline and see what is wrong. Someone who thinks about inference efficiency, model compression, federated learning, and peer-to-peer coordination not as buzzwords but as engineering problems already being solved in their head.

The Mind is probably not working at one of the big labs anymore. Or if so, there for the compute, not the mission. The financial freedom to walk away exists, and what has kept them there is simply the lack of something better to walk toward.

The Mind is one in a million: an AI expert who knows this decentralized future is technically possible, and who has been waiting for someone serious to actually build it.

The Architect of Experience

Where simplicity meets respect

UX/UI Design Visionary

The Architect of Experience has designed interfaces that millions of people use without ever knowing their name. Things were made simple that were impossibly complex. Friction was removed that nobody else even noticed was there.

And then some product manager asked for a dark pattern. Or an engagement trap. Or a notification system designed to create anxiety. And something inside broke a little. Maybe it was done anyway. Maybe there was pushback that got overruled. Maybe the only option was to leave. But either way, this person knows what good design actually means: it means respecting the person on the other side of the screen. Clarity over cleverness. Empathy over engagement metrics. Simplicity that takes ten times longer to achieve than complexity.

This is not a "UX/UI Designer" on a job board. This is someone who sees the invisible architecture of how humans interact with technology, and who knows, with absolute certainty, that most of it is built wrong. On purpose.

The Architect of Experience has already proven the ability to design at the highest level, and is now free enough, financially, creatively, and spiritually, to do their best work for something that actually deserves it.

This is not a contract. This is not a gig. This is a seat at the table of something being built to last, with a name on the foundation. The project is open source. The mission is real. And the interface this person designs may be one of the most important of the next decade.

The Architect of Experience is one in a million: a designer who refuses to compromise on ethics and who believes that simplicity is the hardest and most worthy thing to achieve.

The Keeper

Builds spaces where people belong

Community Leader

Every great project lives or dies by its community. Not the size of it. The soul of it.

The Keeper knows this because communities have been built before. Real ones. The kind where people show up not because of notifications, but because they feel like they belong. Where disagreements happen in good faith. Where moderation means protecting the conversation, not controlling it.

This person has seen what happens when communities are run by algorithms: they polarize, radicalize, and eventually consume themselves. And the Keeper has seen, maybe has built, the alternative. Spaces where people with different views can actually talk to each other. Where trust is the currency and transparency is the rule.

The Keeper is probably not doing this professionally right now. Maybe once. Maybe a forum was moderated, an open source community was led, or something was built from scratch that became bigger than expected. And then a step back was taken, because it was too much work for too little recognition, or because the platform changed the rules underfoot.

This is someone who understands that a community is not a growth metric. It is a living thing that needs a steady hand, clear values, and someone who knows when to speak and when to listen.

The Keeper is one in a million: a community builder who knows the difference between moderation and censorship, and who is ready to build something permanent for a project that deserves a soul.

The One Who Thinks in Atoms

Freedom needs infrastructure

Hardware and Electronics Guru

Most people in tech have forgotten that software runs on something physical. Something that can be touched, broken, controlled, and, most importantly, owned.

The One Who Thinks in Atoms has not forgotten. Hardware is approached the way most people approach apps: as a design space full of possibilities. This person understands that true decentralization does not end at the blockchain. It extends into the physical layer. Into the devices people hold, the networks they connect to, the infrastructure that either belongs to them or belongs to someone else.

Things have been built. Not just prototyped. Built. PCBs, embedded systems, mesh networks, off-grid solutions. The constraints of the physical world are understood: power consumption, signal degradation, thermal limits, supply chains. And those constraints are exciting, not frustrating, because constraints are what separate clever solutions from theoretical ones.

This may be an engineer who left a corporate lab. Someone who fills a garage with oscilloscopes and 3D printers. Someone who has been thinking about decentralized hardware for years and wondering why nobody serious is building it.

This person understands that decentralization means nothing if the physical layer is not free. Real things are built here: circuits, embedded systems, mesh networks. Freedom needs infrastructure, and infrastructure needs someone who can think at the intersection of software and atoms.

The One Who Thinks in Atoms is one in a million: a hardware mind who builds real things and who knows that the next generation of freedom will be engineered, not just coded.

What Makes ZooBC Better

  • Proof of Participation (PoP) consensus: ZooBC combines a permissionless "apply-to-join" federation (the Node Registry) with protocol-enforced rules, aiming to avoid both PoW energy waste and the "rich-get-richer" control dynamics of PoS/DPoS.
  • Rewards tied to measurable network work: Instead of only rewarding block producers, ZooBC introduces a receipt system so nodes can prove they relayed/handled P2P traffic and earn participation score, which then influences rewards.
  • More even block creation / reduced centralization pressure: ZooBC describes block-creation probability in the registry as "more or less equal" across registered nodes, to reduce mining/validator concentration seen in other systems.
  • Fast onboarding via spine blocks + snapshots: Special daily "spine blocks" act as cryptographic checkpoints, pointing to recent database snapshot hashes so new nodes can sync to current state without replaying the entire chain from genesis.
  • Distributed storage for historical data: Old snapshots and block backups are chunked and assigned to nodes deterministically (torrent-like), reducing redundant storage while keeping retrievability decentralized.
  • Account controls and signature flexibility: ZooBC adds features like choosing digital signature algorithms per account and configuring accounts to require approval to receive transactions, targeting higher compatibility with legal/regulatory workflows.

Problems ZooBC Aims to Solve

  • Energy usage and mining centralization (PoW issues): PoP avoids Proof-of-Work's high energy consumption and the tendency for mining power to centralize.
  • Stake/key concentration risks (PoS/federation issues): By requiring participation proofs and using a large registry of nodes, ZooBC argues an attacker must compromise/control many node keys (not just a few wealthy ones) to rewrite history.
  • "Free-rider" nodes that don't propagate traffic: Receipts + participation score are intended to prevent nodes from only chasing block rewards while neglecting gossip/propagation that keeps networks decentralized.
  • Blockchain bloat and slow sync: Snapshots anchored by spine blocks are explicitly designed to make node bootstrap time nearly constant (e.g., "a few minutes" even if the chain is decades old).
  • Overly rigid dApp models: ZooBC positions V1 as groundwork for a later decentralized application platform where subsets of nodes can run specific DApps (a "self-sharding" idea), aiming to avoid the extremes of fully sandboxed smart contracts vs. semi-centralized off-chain apps.
  • Regulated-industry usability gaps: Multi-signature, signature-format flexibility, and "approve-to-receive" account behavior are framed as helping with government/legal compatibility (e.g., signatures recognized in court, explicit consent for attribution of ownership).

ZooBC Supply and Genesis Allocation

ZooBC has a fixed and immutable maximum supply.

Total ZBC supply: 33,333,333 ZBC

No additional ZBC will ever be created beyond this limit.

From this total supply, a strictly limited portion is reserved for early supporters at genesis.

Maximum ZBC allocated at genesis: 3,333,333 ZBC

This is a hard cap. Once this allocation is reached, no further ZBC will be distributed at genesis, regardless of demand.

All remaining ZBC will be distributed exclusively as coinbase through the protocol over time, according to the rules defined by ZooBC.

Genesis Block Accounts

When ZooBC launches, the genesis block will include pre-allocated accounts for early supporters. These accounts are created using BIP39 mnemonics—the same standard used by most cryptocurrency wallets.

How it works

You generate your own BIP39 mnemonic using a trusted, open-source tool.

Recommended method:

Generate a 24-word mnemonic, keep it secure, and never share it.

From this mnemonic, derive your ZooBC account using:

  • Coin name: Zoo Blockchain (fifth from the bottom of the dropdown list)
  • Coin type: 883

A ZBC account address looks like this:

ZBC_T6NDZOTJ_47567SOU_2I4PRNKD_LRNXYJ63_GXQ2OTD4_FVZA4LQT_7Q7KOJ77

You then provide only the public key or address derived from your mnemonic.

This public information is used to include your account in the ZooBC genesis block with the allocated ZBC amount.

You retain full control at all times:

  • Your mnemonic and private keys never leave your possession
  • ZooBC never has access to them
  • There is no recovery if you lose them

At this stage, hardware wallets are not supported. Support may be added in the future, but genesis accounts are currently created using software-generated BIP39 mnemonics only.

Support Packages

Supporter – 1,000 USDT

  • 10,000 ZBC in genesis block
  • Name listed on supporters page
  • Early access to testnet

Builder – 5,000 USDT

  • 50,000 ZBC in genesis block

Important Notes

  • This is not an ICO. There is no token sale.
  • ZooBC main net will launch before end 2026. Follow the blog or this website for a precise date (when it is announced, rephrase it).
  • Genesis allocations are rewards for early supporters, not investments.
  • ZBC tokens have no guaranteed monetary value.
  • Support ZooBC because you believe in the technology.
