RIZON NEBULAE Upgrade Notice

Titan Upstream & Integration Cosmwasm



Hello, this is RIZON.

RIZON is a digital currency and asset hub. To expand the RIZON Blockchain ecosystem and realize our new vision, RIZON will continue to navigate and pioneer Web3.0. With this in mind, RIZON proposes NEBULAE UPGRADE. This upgrade will feature the Cosmwasm smart contract platform and will support NFTs through smart contracts.


NEBULAE is a collection of gas and dust that exists between stars and is made up of nebulas. A nebula can be divided into several categories according to the way it reveals itself. Like a nebula that exists between stars, RIZON will serve as a link between all blockchains that wish to join the RIZON ecosystem and support the service base in joining the RIZON’s ecosystem.

  1. Support NFT: With a NEBULAE upgrade, RIZON with Cosmwasm can support NFTs through smart contracts. NFTs will be used as a value storage method that can store more diverse digital assets. To allow more services to join the RIZON ecosystem, we will also add a simple DAPP example, NFT Finder, that utilizes NFTs in the RIZON ecosystem. This will enable various DAPPs to be active in the RIZON ecosystem. Additional information on this can be found in a later notice.
  2. Support DeFi: Cosmwasm not only supports NFTs but also supports DeFi DAPPs. Based on the decentralized permissionless smart contract platform RIZON, various DeFi DAPPs can be formed to build a unique ecosystem. In addition, RIZON plans to actively utilize the existing RIZON ecosystem grants to build a sustainable development environment.


The RIZON mainnet (a.k.a Titan) upgrade is expected to occur at a block height of 9,500,000.


· Add CosmWasm module

· Introduce cw-721 NFT contract and NFT Finder

· Upgrade Tendermint to Comet BFT v0.34.29

· Bump Cosmos SDK to v0.45.16

· Bump IBC Go to 4.4.2

On-Chain Upgrade Process

When the network reaches its halt height via on chain governance proposal, RIZON’s state machine program comes to a pause. We would need to replace the state machine binary with a new one. To exchange binaries, the two can be swapped either manually or automatically through Cosmovisor.

Both operation and maintenance of nodes (verifier nodes or full nodes) require software upgrades. Details will be provided on official document and discord.

Mainnet upgrades cannot happen without Rizonians. Always stay safe by backing up the wallet mnemonic or keystore file where you staked your RIZON coins. Participate in governance proposals and vote through supported wallets or other tools. Rizonians’ voting is essential for upgrades!

RIZON: Possibility to Reality

The RIZON blockchain and RIZON ecosystem are growing. To build a global infrastructure, all participants are invited to contribute and propose ideas. RIZON will continue to develop and evolve to build the most powerful decentralized digital currency and asset hub and go on to innovate Web3 applications.


RIZON Blockchain is a digital currency and asset hub that provides a platform for businesses to securely issue fiat currencies around the world so that they can interoperate with each other. RIZON Blockchain enables interoperability between sovereign blockchain networks and provides an environment where these networks can leverage vast liquidity pools to meet the business needs of individual projects. RIZON Blockchain has a strong network background and can promote the influx of ecosystem participants and business diversification.


This is not financial advice. Staking, delegation, and cryptocurrencies involve a high degree of risk, and there is always the possibility of loss, including the failure of all staked digital assets. Additionally, delegators are at risk of slashing in case of security or liveness faults on some protocols. We advise you to do your due diligence before choosing a validator.
