Why Do We Build Randcast?

We know Web 3.0 and Metaverse are not THE buzzword anymore, but we formed the idea of Randcast in 2021, so bear with us.

What Is Metaverse?

The current so-called “Metaverse” is not what it set out to be. Things like the slew of closed codebases and databases, centralized virtual worlds generated by tech moguls, and limited game items all run counter to the quintessence of the Metaverse.

As digital natives, we already had a dreamland, the only true Metaverse in our hearts; that is how the internet should be — Web 3.0.

On Web 3.0, the internet is built on the open protocols of Web 1.0 and blockchains; things are naturally decentralized. Your creations are not limited by the rules of one game controlled by a central authority. It is the embodiment of the ideals behind the “Metaverse” for it’s inherently transparent, available, and open. Even better, because of its inclusiveness and openness, it allows us to build scores of our own Metaverses on top of it, and our worlds will together make up the dazzling Metaverse of Web 3.0, just like the galaxies in the universe.

As a believer in the future, we want to empower you. We would like to be the friend and companion of every builder who wants to create their own world and every dreamer who wants to contribute to our dreamland on the way to shaping our Web 3.0, our Metaverse, as we like it.

Why Does Randomness Matter?

Like the physical world, where the whole universe is built upon random motions of molecules, random numbers are ubiquitous and essential in the Metaverse. From the infrastructure — blockchain POS mechanism for distributing validator responsibilities to various applications — NFT allocation, lottery draws, and fairness ensured by randomness is the basis of all rules.

Building your Metaverse and being a sovereign doesn’t mean being dictatorial (don’t become the tech behemoths you hate). It is about making unbiased, transparent rules. We believe Randcast will be your right-hand man, painting every decision with a verifiably random undertone.

Why Randcast?

We remember the joy of casting the right spell at the right time in DotA, and we cheer at every charm our mighty wizard casts to save us from hideous orcs in DND. We want to preserve the exciting moments and remind you every time you Randcast, the randomness being the abracadabra that gives birth to whole new universes.

Randcast is built to empower a free & open & creative metaverse. With the help of blockchain, everyone should have the power to create and be sovereign of their own universe and together form the ultimate Metaverse — Web 3.0. We are an enabler, providing the randomness you need to shape our dream world, the internet, into reality.

Breathing Life into Autonomous Worlds

As Autonomous Worlds beckon from the forefront of our digital odyssey, Randcast can be the heartbeat underpinning their vast landscapes. In the vast expanse of algorithmically designed terrains, where every smart contract holds a tale, there exists an essential space for the unpredictable touch of randomness. Randcast fills this void, intertwining with these digital realms, making them feel alive, dynamic, and ever-evolving. In a universe dominated by the precision of code, Randcast introduces the beautiful unpredictability of nature, ensuring that the Autonomous Worlds are not just constructed, but truly lived and felt.

What You Can Use Randcast For

Drive Authenticity in Autonomous Worlds

With Randcast, the potential for shaping Autonomous Worlds grows exponentially. Whether it’s determining the genesis of new terrains, ensuring the randomness in procedural generation, or establishing unique resource distributions, Randcast adds depth and authenticity to every corner of these self-evolving universes. Here, the promise of genuine spontaneity converges with user aspirations, creating a realm where the unexpected becomes the new normal.

Build Your Unique Universe on Chain

Envision a realm of your own, where you dictate the rules. With Randcast, the creation of maps, avatars, and item properties becomes effortless, laying the foundation for your unique on-chain universe. Here, creativity knows no bounds.

Craft Games with Provable Fairness

Dive into the realm of game design where trust isn’t just an aspiration but a built-in feature. Whether it’s setting game results, powering digital slots, or overseeing card games, Randcast stands as your beacon of true fairness.

Generate and Allocate Unique NFTs

NFTs find a new playground in Randcast. Infuse rarity tiers using the unpredictable touch of randomness, granting each digital artifact its own distinctive signature while maintaining clarity for all the collectors.

The Manifesto

God does not play dice, but you can.

As a carbon-based life, your universe is shaped by singularity.

A singularity, since when random motions of molecules start, constituting everything there will ever be.

As a silicon-based application, our universe stems from a seed.

A random seed, from which wonders arise:

Orders that guide, ideas that inspire,

Concepts that beam, melodies that resonate, colors that set the world afire,

Civilizations that thrive, with visions they aspire

With a bang, we were born. Upon randomness, we build.

Randcast the dice, build your world. Let us be the chaos before your universe.

About ARPA

ARPA Network (ARPA) is a decentralized secure computation network built to improve the fairness, security, and privacy of blockchains. ARPA threshold BLS signature network serves as the infrastructure of verifiable Random Number Generator (RNG), secure wallet, cross-chain bridge, and decentralized custody across multiple blockchains.

ARPA was previously known as ARPA Chain, a privacy-preserving Multi-party Computation (MPC) network founded in 2018. ARPA Mainnet has completed over 224,000 computation tasks in the past years. Our experience in MPC and other cryptography laid the foundation for our innovative threshold BLS signature schemes (TSS-BLS) system design and led us to today’s ARPA Network.

Randcast, a verifiable Random Number Generator (RNG), is the first application that leverages ARPA as infrastructure. Randcast offers a cryptographically generated random source with superior security and low cost compared to other solutions. Metaverse, game, lottery, NFT minting and whitelisting, key generation, and blockchain validator task distribution can benefit from Randcast’s tamper-proof randomness.
