What is QuantumCoin [OLD] (QE)?
QuantumCoin with the ticker QE is the native utility token for the Quantum Economics ecosystem. This project focuses on the intersection of artificial intelligence, blockchain technology, and the tokenization of real-world assets. The designation OLD specifically refers to a legacy version of the token that was used before a recent contract migration. Such migrations are typically performed to upgrade the smart contract features, enhance security, or move the project to a different blockchain infrastructure. Users holding the legacy version are generally required to swap their tokens for the updated version to maintain utility within the ecosystem. The core mission of the Quantum Economics project is to democratize access to generational wealth. It aims to achieve this by tokenizing high-value physical assets that were historically difficult for individual investors to access. One of the primary examples includes tokenizing energy-related royalties, such as oil and gas interests, allowing for fractional ownership. This approach is intended to provide a bridge between traditional financial markets and the decentralized economy. From a technical perspective, the project emphasizes security against future computing threats. It features a suite of tools including the Qubit Wallet, which is described as an institutional-grade digital wallet designed with quantum-resistant security. The ecosystem also plans for the Quantum Grid, a post-quantum blockchain intended to handle fractional ownership, compliance, and interoperability between different networks. The project utilizes NIST-standardized cryptography to protect against both classical and quantum computer attacks. Quantum Economics is described as a community-driven initiative with no centralized owner. It operates under a philosophy where the community members contribute to the development and direction of the project. The vision for the ecosystem involves creating a self-sustaining loop where economic activity within the network fuels further development and the acquisition of more tokenized assets. The project positions itself as a leader in the transition to what it calls the Quantum Era of finance, focusing on transparency and accessibility through blockchain technology. Learn more

QuantumCoin [OLD] (QE) FAQ
The [OLD] label indicates that this asset is the legacy version of the project. QuantumCoin migrated from its initial state on existing networks to its own independent Layer-1 blockchain (Mainnet), which launched on December 31, 2023. This version represents the project's earlier stage before the mainnet transition.
To swap legacy QE tokens for the new mainnet coins, holders are typically required to use the project's official Desktop or CLI Wallet. The process involves a "burn" or "claim" mechanism where old holdings are swapped for the new Layer-1 assets. While the legacy ticker is QE, the new mainnet coin is referred to as QuantumCoin (Q).
QuantumCoin was formerly known as Doge Protocol (DogeP). The project rebranded to better reflect its technical focus on "Quantum Resistance." Legacy DogeP tokens are generally still valid for the migration process, allowing long-term holders to transition their assets to the current Layer-1 mainnet.
The project utilizes NIST-standardized post-quantum cryptography, including algorithms like Dilithium and Kyber, to protect the network against future quantum computer attacks. It employs a hybrid security approach, ensuring the blockchain remains secure against both classical and quantum computing threats.
The migration to the Layer-1 mainnet included a significant change in total supply. The legacy QE token had a maximum supply of 100 billion, while the new QuantumCoin (Q) mainnet coin has a total supply of 100 trillion. This adjustment was made to support the new independent blockchain ecosystem.
The [OLD] version is still found on various decentralized exchanges. To ensure you are trading the correct version, users should consult official project documentation or use supported platforms like LBank. The new mainnet coin requires the project's specific wallet or exchanges that have integrated the Layer-1 mainnet.
