VargaCoin. Technical overview.
How the VGC network works today, which rules are already implemented, and which Mainnet parameters remain subject to final consensus hardening.
This is technical project documentation for the VargaCoin DEV network. It is not a MiCA crypto-asset white paper, not an offer to purchase VGC, not a solicitation, and not an application for admission to trading.
An independent public ledger for VGC.
VargaCoin is an independent proof-of-work blockchain with VGC as its native asset. It is not a token on another chain and it is not pegged to Bitcoin, the euro, the forint or any national currency.
The current public DEV network exists to test consensus behavior, SHA-256D ASIC mining, wallets, transactions, explorer data, coinbase maturity and network operations before a separate Mainnet launch.
Full nodes validate one VargaCoin chain.
VargaCoin Core is derived from Bitcoin Core 31.1 and uses its UTXO transaction model, script validation, SegWit/Taproot-era primitives and peer-to-peer node architecture, with VargaCoin-specific chain parameters and branding.
Each full node independently validates block headers, proof of work, transactions and consensus rules. Explorer and pool data are convenience views; the chain accepted by validating nodes is authoritative.
Open SHA-256D mining.
Compatible SHA-256D ASICs search for block headers below the VargaCoin network target. The public Stratum service distributes jobs and lower-difficulty pool shares; only work that also satisfies the network target can become a VargaCoin block.
Pool share difficulty and network difficulty are different values. A share proves work to the pool; a block must satisfy the current VargaCoin consensus target.
The public DEV chain currently uses a 150-second spacing, a 24-hour retarget window (576 blocks) and DEV min-difficulty behavior. This is intentionally not declared final Mainnet consensus. The Mainnet difficulty algorithm will be selected, tested and frozen before the release candidate.
Ownership is represented by spendable outputs.
VGC transactions spend existing UTXOs and create new outputs. Nodes verify signatures, scripts, amounts and applicable consensus conditions before accepting transactions and blocks.
A VGC receiving address is public routing information, not a private key. The private key or WIF controls spending and must remain secret.
Newly mined coinbase outputs currently require 100 additional blocks before becoming spendable. Wallet and explorer interfaces distinguish immature mining rewards from spendable balance.
Predictable issuance, subject to final Mainnet freeze.
The intended Mainnet monetary schedule starts at 12.5 VGC per block and halves every 840,000 blocks. At a 150-second target interval this is approximately one halving every four years and implies an intended maximum issuance of about 21 million VGC, subject to final implementation and rounding verification before code freeze.
VGC has no guaranteed market price. If VGC is later traded, market value is determined by independent buyers and sellers and can fall to zero.
Mainnet starts from a new genesis. DEV history is not destroyed.
The current DEV chain and future Mainnet are separate ledgers. DEV blocks, DEV balances and mined DEV-VGC are not copied, swapped or automatically credited to Mainnet.
At Mainnet launch, every Mainnet balance starts from the new final genesis and public mining rules. A wallet may technically use the same key material if formats remain compatible, but its Mainnet balance begins at zero; generating a fresh Mainnet wallet is recommended to avoid network confusion.
The project plan is to preserve the DEV chain as a read-only historical test archive after Mainnet, so early ASIC blocks, transactions and test results remain verifiable even though DEV-VGC has no Mainnet balance.
Self-custody means the key controls the coins.
VargaCoin supports native bech32-style addresses beginning with vgc1. The VargaCoin Web Wallet generates or imports keys locally, encrypts browser-held private key material and signs transactions on the client before broadcast.
A WIF is an export representation of a private key. Anyone who obtains a valid private key can spend the outputs controlled by it. Users should maintain secure backups and never publish WIF/private-key material.
Pool accounting and on-chain evidence are different layers.
The public pool accepts Stratum shares from compatible SHA-256D miners. Share records measure contributed work, while a block reward exists only when a candidate block is accepted by the VargaCoin network.
Block hashes, heights, transactions and reward outputs should be verified in the Explorer or directly through a validating VargaCoin node. A pool dashboard alone is not consensus evidence.
Proof of work is only as strong as the work securing the chain.
A young SHA-256D network can be exposed to sudden hashrate changes, rented hashrate, deep reorganizations and timestamp/retarget edge cases. These are core reasons the current network is explicitly a public DEV phase.
Before Mainnet, the project intends to freeze and test an adaptive difficulty design, test reorg behavior, run multiple independent full nodes, publish reproducible releases and complete the Mainnet go/no-go checklist.
No technical document or software design can guarantee future market value, uninterrupted operation or immunity from software and network failures.
