Most people who dip a toe into cryptocurrency only ever hear two or three names — Bitcoin, Ethereum, maybe Dogecoin. But because Bitcoin’s code was open for anyone to build on, a whole family of other blockchains launched in its wake. DigiByte is one of the oldest of them that’s still running today — it went live on January 10, 2014, which actually makes it older than Ethereum. That longevity makes it a genuinely useful example for understanding how a real, still-maintained blockchain works, without the noise of a brand-new coin.
So what is DigiByte? In plain English: it’s a public, decentralized blockchain and cryptocurrency (ticker: DGB), built in the Bitcoin tradition but tuned for speed, security, and decentralization. This guide explains what it is, where it came from, what genuinely makes it different — and, just as importantly, separates the verifiable facts from the enthusiastic marketing that surrounds it. (One note up front: this is education, not financial or investment advice — there’s no price talk here.)
The Basics: A Faster Cousin of Bitcoin
DigiByte sits squarely in the Bitcoin lineage. It’s a “proof-of-work, UTXO-based” blockchain — which sounds technical but just means it works much like Bitcoin under the hood, with some deliberate changes.
Two quick concepts make the rest make sense:
- Proof-of-work is the system where computers (“miners”) compete to solve hard math puzzles to add the next batch of transactions and secure the network — the same energy-based security Bitcoin uses.
- UTXO (“unspent transaction output”) is the accounting model. Instead of thinking of your balance as a single number in a bank account, picture a wallet full of individual bills and coins. When you pay someone, you hand over specific bills; if you don’t have exact change, you get change back as a new bill. Each “bill” is a UTXO. Bitcoin works this way, and DigiByte inherited the same model. (Ethereum, by contrast, uses simple account balances.)
DigiByte was originally built from existing Bitcoin-family code (widely reported as based on Litecoin, itself a Bitcoin fork) but launched as its own independent blockchain with its own first block — not a copy of Bitcoin’s ledger. Its code is still kept in sync with upstream Bitcoin, so it stays technically current.
The Origin Story: No ICO, No Company
Here’s what makes DigiByte an unusually clean case study for a beginner trying to tell a genuine open-source project from a marketing-driven token.
DigiByte was created by Jared Tate, who by his own account put in roughly $500,000 and over 10,000 hours. Crucially, it launched with no “initial coin offering” (ICO) — there was no sale of coins to the public to enrich the founders — and no company owning or controlling it. It was built, largely given away, and handed to a global community of volunteers. There is no CEO and no corporation steering the DigiByte blockchain. (We tell the fuller founder story in who created DigiByte.)
One honest correction, because you’ll see the claim “no premine” repeated everywhere: it’s not quite true. There was a tiny premine — about 0.5% (~105 million DGB) — but it was given away to early users and used to fund roughly the first 18 months of development, with none retained by the founder. So the accurate framing is “0% remaining premine,” not “no premine at all.” It’s a small distinction, but this whole guide is about getting the facts straight rather than repeating fan enthusiasm.
There’s a nice symbolic detail, too. Like Bitcoin’s first block (which quoted a newspaper headline about bank bailouts), DigiByte’s very first block has a headline permanently embedded in it: “USA Today: 10/Jan/2014, Target: Data stolen from up to 110M customers.” It references the 2013 Target retail data breach — signaling the project’s stated focus on cybersecurity from day one.
What Actually Makes DigiByte Different
Strip away the superlatives and a few genuine, verifiable design choices stand out:
Five mining algorithms instead of one. Bitcoin secures itself with a single algorithm (SHA-256). DigiByte uses five — SHA-256, Scrypt, Skein, Qubit, and Odocrypt — with blocks rotating between them. The idea is decentralization and security: to attack the chain, you’d have to dominate multiple independent mining systems at once, not just one. (Note: if you’ve read older guides listing “Groestl” as one of the five, that’s out of date — Odocrypt replaced Groestl in a 2019 upgrade. We cover this in DigiByte’s mining algorithms.) Odocrypt is especially clever: it rewrites itself every 10 days to stay resistant to the specialized mining hardware (ASICs) that tends to centralize other coins.
DigiShield — an innovation others copied. DigiByte pioneered DigiShield, a system that re-adjusts mining difficulty in real time (roughly every block) instead of every couple of weeks like Bitcoin. It protects smaller chains from being wrecked by miners piling on and then leaving. It worked well enough that other cryptocurrencies adopted it — including Dogecoin and Zcash.
Speed. DigiByte targets a 15-second block time — blocks arrive about 40 times more often than Bitcoin’s ~10 minutes. (That’s block speed; you’ll also see big “transactions per second” figures quoted, but treat those as theoretical maximums, not sustained real-world throughput.) DigiByte was also the first major coin to activate SegWit (an efficiency upgrade) back in 2017.
More than a coin — three layers. DigiByte describes itself as three stacked layers: the low-level network and protocol at the bottom, the public transaction ledger in the middle, and an applications layer on top. That top layer includes DigiAssets (a way to issue your own tokens and digital assets on the DigiByte chain) and DigiID (a way to log into websites using your wallet instead of a password).
The Numbers: 21 Billion, Not 21 Million
DigiByte’s supply is a deliberate contrast with Bitcoin. Where Bitcoin caps at 21 million coins, DigiByte caps at 21 billion DGB — a 1,000-to-1 ratio, chosen partly so the per-coin price stays low and the units feel usable for everyday amounts. That full supply is scheduled to finish being mined around 2035, released on a smooth schedule that shrinks the mining reward by about 1% each month. As of 2026, roughly 88% (about 18.4 billion DGB) has already been mined. (We break the economics down in DigiByte’s tokenomics — again, as protocol facts, not investment guidance.)
The Honest Picture (Reading Past the Hype)
Here’s the part most DigiByte write-ups skip. The community enthusiastically markets it as “the world’s most secure, fastest, and most decentralized UTXO blockchain.” Those are claims, not verified facts — and notably, DigiByte’s own website hedges to “one of the fastest and most decentralized,” which is the fairer framing. Bitcoin, for instance, has a far larger security budget in absolute terms.
A clear-eyed summary: DigiByte is a genuinely old (2014), still-actively-developed, no-ICO, volunteer-run blockchain with some real technical firsts to its name (DigiShield, multi-algorithm mining, early SegWit). It is also a small-cap coin with modest real-world adoption compared to the giants. Both things are true at once. And one specific myth worth retiring: DigiByte is sometimes called “quantum-proof,” but it uses the same kind of cryptographic signatures as Bitcoin — it is not post-quantum, and that label is an overstatement (more in is DigiByte quantum-resistant?).
Hold both the strengths and the limits in view and you’ll understand DigiByte better than most of what’s written about it — which is exactly the point of learning the facts instead of the folklore.
❓ Frequently Asked Questions
What is DigiByte (DGB)? DigiByte is a public, decentralized, proof-of-work blockchain and cryptocurrency launched on January 10, 2014. It’s built in the Bitcoin lineage (a UTXO-based chain) but tuned for faster blocks (15 seconds), stronger decentralization (five mining algorithms), and extra features like issuing digital assets and password-less logins. Its coin’s ticker is DGB.
Is DigiByte the same as Bitcoin? No, though they’re related. DigiByte started from Bitcoin-family code and works similarly, but it’s an independent blockchain with its own history. Key differences: 15-second blocks (vs. ~10 minutes), five mining algorithms (vs. one), and a 21-billion coin supply (vs. 21 million). Both are UTXO payment-focused chains rather than smart-contract platforms like Ethereum.
Who created DigiByte, and does a company own it? It was created by Jared Tate in 2014. No company owns or controls it — there was no ICO and no corporation; it’s run by a global community of volunteers with no CEO. There was a small (~0.5%) premine that was given away and used to fund early development, so “0% remaining premine” is the accurate description.
What makes DigiByte’s security different? It uses five mining algorithms (SHA-256, Scrypt, Skein, Qubit, and the self-changing Odocrypt) instead of one, so an attacker would have to dominate several independent mining systems at once. It also pioneered DigiShield, a real-time mining-difficulty adjustment later adopted by other coins. These are real advantages, but “most secure” and “quantum-proof” are marketing claims, not verified facts.
Is DigiByte still active in 2026? Yes. Its open-source software is still actively maintained (kept in sync with upstream Bitcoin Core), with ongoing development and releases, and the community continues to work on new features. Note that “actively developed” is a signal of project health, not of price or value — this guide makes no investment claims.
