A live, proof-of-work blockchain built around native quantum-resistant ownership.
⚠ v2.0.3 — VCIP-3 MANDATORY HARD FORK — ACTIVATES BLOCK 32,000 ⚠
🔷 WHAT IS VOIDCOIN?VoidCoin is a SHA256d proof-of-work cryptocurrency with native quantum-resistant address support. While most cryptocurrencies remain vulnerable to future quantum computing attacks against their underlying signature schemes, VoidCoin introduces
P2QR (Pay-to-Quantum-Resistant) addresses natively at the protocol level — giving holders quantum-safe custody from block one, not as something bolted on after the fact.
"When quantum computers arrive, VoidCoin holders are safe. Are you?"

🔷 NEW IN v2.0.3 — VCIP-3This is a coordinated, mandatory hard fork. Everything below activates atomically at
block 32,000:
- Hard supply cap enforcement — cumulative issuance is now deterministically clamped to the full 231M VOID max supply at the consensus level.
- P2QR Time-Lock outputs go live — vqt1... addresses become spendable on-chain. Lock funds to an absolute block height or an absolute median-time-past (BIP-113 style), enforced entirely by consensus — no trusted third party, no custodian.
- Up to 58% faster transaction validation — the signature-hash routine previously recomputed transaction-wide data for every input, scaling quadratically. v2.0.3 computes it once per transaction and reuses it (the standard BIP-143 pattern), cutting full validation time on large multi-input transactions by roughly 58%. Byte-for-byte identical output — verified against live chain history.
- P2QR multisig vault — M-of-N post-quantum multisig, up to 1024-of-1024 signers, with a full create → approve → broadcast workflow.
- ML-DSA verification budget — blocks are capped at 8,000 ML-DSA-87 verifications, bounding worst-case block validation cost as multisig usage grows.
- Post-quantum wallet encryption — P2QR seed material is now encrypted under your wallet's master key on the same footing as any other key. Existing wallets migrate automatically on next unlock.
🔷 THE VOID COLLAPSE BOUNTY BLOCKEvery single block has roughly a 1-in-500 chance of paying out 200 VOID instead of the normal 50 VOID reward — 4x the subsidy — determined entirely by the resulting block hash, and unknowable to the miner until the exact instant the block is solved.
We call it the
Void Collapse Bounty Block — named for quantum wave function collapse. Until the moment you solve a block, it exists in superposition as simultaneously a bounty block and not a bounty block. The instant your hash lands, the wave function collapses and you find out which one you got. Schrödinger's Block, live on a real blockchain.
The mechanism is fully transparent and verifiable by any node: the first 3 bytes of the block hash are checked against a fixed threshold. No trusted party, no off-chain randomness, no lottery contract — it's baked directly into consensus. And it's supply-aware: the bounty automatically and permanently disables once fewer than 200 VOID remain to be mined before the hard cap, and stays disabled through the post-halving 0.1 VOID/block tail emission that keeps the network secured forever.

🔷 ADDRESS TYPESThe VoidCoin Core wallet exposes address formats backed by post-quantum key material:
- vqr1... — Native quantum-resistant P2QR address ⚛️
- vqt1... — P2QR Time-Lock address (new in v2.0.3) — funds locked to an absolute height or time, enforced by consensus
- 3... — Wrapped P2SH address, for mining pool / legacy software compatibility
All address types are backed by ML-DSA-87 — there is no legacy elliptic-curve address type on this chain to opt out of.

🔷 NO DEV FUND — FULL TRANSPARENCYVoidCoin Core was forked from Kvanta5-Core. During initial mainnet bootstrap, the following consensus-affecting change was made
prior to any blocks being mined:
The inherited codebase reserved block 1 as a special "dev fund" block, requiring its coinbase transaction to contain exactly 21 hardcoded outputs totaling 21,000,000 VOID, with normal mining beginning only at block 2.
This allocation was completely removed before mainnet launch. As a result:
- Block 1 is a normal proof-of-work block, mined like every other block.
- The standard 50 VOID block subsidy applies starting from block 1, with the usual halving schedule.
- There is no dev fund, no team allocation, and no pre-mined balance anywhere in VoidCoin's supply. All 231,000,000 VOID will be distributed exclusively through mining.
Anyone auditing the chain from genesis will see block 1 as an ordinary 50 VOID coinbase with no special-cased outputs — fully verifiable on-chain and in the source history.
🔷 SECURITY — AUDITED AS WE GODuring pre-fork review ahead of v2.0.3, we found and closed — before it was ever exploited — a gap where a change removing the old, never-launched dev-fund mechanism had also accidentally removed the standard coinbase-maturity enforcement (the rule requiring 100 confirmations before a mined block reward can be spent). We ran a full scan of every block from the point the gap was introduced to the chain tip: zero violations found. It's closed as of v2.0.3. We're disclosing this because a project that hides its own bug reports isn't one you should trust with your coins.
🔷 THE TOOLSVoidCoin isn't just a chain — it's a growing set of tools putting post-quantum cryptography to work for things people actually want to do, all live at void-coin.net:
⏱ Quantum Threat ClockA live, visible reminder of the quantum threat every non-post-quantum chain is racing against — and why "deal with it later" was never VoidCoin's strategy.
📜 Proof of ExistenceHash any document or text, sign it with your wallet — your key never leaves your browser — and stamp that hash permanently into a VoidCoin transaction's OP_RETURN field. Immutable, timestamped proof your content existed at a specific point in time, verifiable by anyone forever.
⏳ Void Inheritance ProtocolPlan exactly how your VOID gets distributed to heirs — source address, heir addresses, split percentages, unlock date — generated entirely client-side, with zero private keys ever stored anywhere.
🎁 VOID Gift Card GeneratorGenerate a fresh, post-quantum paper wallet formatted as a printable gift card. Fund it from your own wallet, print it, hand it to anyone — no app, no seed-phrase onboarding required from the recipient. Every key is generated entirely in-browser via audited open-source cryptography — nothing ever touches a server.
💼 Web WalletFull-featured browser wallet — send, receive, and generate P2QR-TIMELOCK addresses without installing anything.
🔷 MININGVoidCoin uses SHA256d — compatible with any standard SHA256d miner including CGMiner, BFGMiner, and CPUMiner-Multi.
stratum+tcp://<pool-address>:<port>
Username: your VOID address
Password: x
Both P2SH (
3...) and quantum-resistant (
vqr1...) addresses can be used as the mining username, depending on pool support.
