A Post-Quantum Secure, High-Speed Decentralized Peer-to-Peer Electronic Cash Sys

[dragoncoin2009]

Abstract
Dragonchain is a decentralized peer-to-peer electronic cash system based on proof-of-work (PoW) consensus, built on Sugarchain's PoW and difficulty-adjustment parameters (5-second blocks, Yespower, SugarShield-N510), with the signature algorithm replaced by post-quantum secure Falcon-512 (drawing on Tidecoin's post-quantum security approach). Dragonchain achieves one of the fastest PoW transaction confirmations in the world with 5-second block times, employs the Falcon-512 post-quantum signature algorithm to resist future quantum computer attacks, and realizes "one-CPU-one-vote" decentralization through the Yespower CPU-friendly mining algorithm. Dragonchain has never conducted an ICO, premine, or private sale — it is a fully fair-launch, community-driven project.

1. Introduction
Bitcoin [1], as the first successful decentralized digital currency, demonstrated the feasibility of electronic payment systems based on cryptographic proofs. However, as blockchain technology has evolved, Bitcoin faces two fundamental challenges:

Slow Transaction Confirmation: Bitcoin's 10-minute block time cannot meet the demands of everyday payments
Quantum Computing Threat: Bitcoin's ECDSA signature algorithm offers no security against quantum computers [2]
Dragonchain addresses both challenges with a systematic solution: - 5-second block time, 120x faster than Bitcoin - Falcon-512 post-quantum signature algorithm, resistant to quantum computing attacks

Dragonchain strictly adheres to Satoshi Nakamoto's "one-CPU-one-vote" principle. Through the Yespower algorithm, mining power is distributed across a wide range of CPU devices, rather than concentrated in GPU farms or ASIC miners.

Put 2,827,423 coins (41.33%) into his own wallet and is looking for fools to support his network. Haha.

His White Paper has no pre-mine, so how does he have so much already? Did you verify this. It has a standard block reward of 0.20807311 DRAGON so it would take him forever to mine that much. Also it has a max supply of 21 million so it would be more like 10%. I'm not defending it, I'm trying to understand.


I checked the block explorer. The mining reward is actually 3.32988658 and the supply is 6.9 million my numbers were wrong but the chain is already at block 2 million something so he's been mining the heck out of this thing alone. This is very strange behavior and his whitepaper number don't align to the reward being mined. All of this is strange.

The mining reward actually aligns with the whitepaper figures because the coin is currently in the "Initial Period Reward" phase (the first ~6 months). After that, it drops to 0.20807311 DRAGON per block and halves every 4 years.

However, the issue is that the genesis block timestamp is May 4, 2026, which means he launched the coin and started solo mining long before announcing it anywhere—even before launching the official website or publishing the code on GitHub. Yet, he claims it was a fair launch with no pre-mining... Hmm.
