Before you start

What this is

Litecoin is its own network. It is not leftover Bitcoin.

Litecoin is an open payment network launched in 2011. It borrowed ideas from Bitcoin and then ran its own ledger, miners, and rules.

This book is for a beginner who wants the birthday, the premine fact, the 84-million design, and the optional privacy feature—without slogans.

MWEB is opt-in. It is not Monero. Not every wallet supports it.

Educational information only. Not financial, investment, legal, tax, or trading advice. Dates, supply figures, and court records in this book are taken from the sources listed at the back. If a fact is not sourced, it is not printed as a fact. Unverified items stay open.

How this book is built

Day the coin was born

13 October 2011 UTC (public launch)

October 7 and October 13 2011 are different events. Do not pick one and call it “the birthday” without saying which. A 2014 edit of the first post says “Oct 12 03:00 GMT.” 13 October 2011 was Thursday; 12 October was Wednesday. Treat “Oct 12” as an edit error.

Name the event you are dating. “Launched” without a layer is how slogans start.
Event	Date	What that date is
Genesis header nTime	7 October 2011, 09:31:05 UTC	Unix 1317972665 in chainparams CreateGenesisBlock. A field, not the public launch.
Forum ANN opens	9 October 2011	coblee, Bitcointalk topic 47417.
Public launch (genesis hash released)	Thursday 13 October 2011, ~03:00 GMT	coblee edit 14 Oct 2011: “Litecoin was launched on Thursday Oct 13, 03:00 GMT.”

Charlie Lee (coblee) created Litecoin from Bitcoin-family open-source code. The Bitcointalk announcement thread is the primary public launch record.

The genesis coinbase is Litecoin’s answer to Bitcoin’s Times headline: “NY Times 05/Oct/2011 Steve Jobs, Apple’s Visionary, Dies at 56.” The apostrophe is a Unicode right single quotation mark, not ASCII.

Do not call the launch “zero premine.” The announcement has a heading called “Premines”: “Litecoin will come with 150 premined coins.” Genesis plus the first two blocks, 50 LTC each. The “no premine” myth starts in that same thread, reply #12, the same morning.

People and projects

Who is behind it

The launch ANN is signed coblee, forum tagline “Creator of Litecoin.” LIP-0003 author line: Charlie Lee. An “ex-Google” employer biography is unverified in the research pack. This book does not print it.

No protocol CEO. litecoin.org is the official project starting point. Miners, node operators, and wallet makers are independent.

“Silver to Bitcoin's gold” is the launch announcement’s own marketing phrase. Quote it as a 2011 quote, not as an analysis.

Place and lineage

Where it came from

Litecoin came from Bitcoin-family open source, announced on Bitcointalk, using Scrypt from the Tenebrix line of experiments.

coblee wrote that using Scrypt “allows one to mine Litecoin while also mining Bitcoin.” That is hardware non-contention in 2011 — different algorithms, so one machine can do both without fighting for the same GPU path. It is not AuxPoW and not merge-mining Litecoin.

Dogecoin later added AuxPoW so Dogecoin can accept Litecoin work. Litecoin itself is Scrypt-only.

Keep these separate

What it is and is not

It is

A separate proof-of-work payment network using Scrypt.
A chain with a designed maximum of about 84 million LTC — four times Bitcoin’s unit count, with blocks targeted about four times as often. Charlie wrote “about 84 million.” The subsidy function sums to 83,999,999.9076 LTC (derived). “Exactly 84 million” is false.
A network that later added optional MimbleWimble Extension Blocks (MWEB).

It is not

Bitcoin on another sticker.
A chain whose circulating supply is exactly 84 million today. That number is a rounded design target, not the live spendable count and not 84,000,000.00000000.
Monero. MWEB is opt-in and wallet support varies. MWEB also has a consensus freeze list.
A zero-premine launch. One hundred fifty coins were created before open mainnet mining, under a heading called “Premines.”
Merge-mined or dual-algorithm. Litecoin is Scrypt-only. Dogecoin merge-mines Litecoin via AuxPoW on the Dogecoin chain.

The machine

How it works

Agreement method: Scrypt proof of work. Target block interval about 2.5 minutes.
Units: LTC, divisible like bitcoin-family coins.
Issuance: About 84 million LTC under the current subsidy function, not an exact 84,000,000.00000000. Derived sum of integer subsidies × 840,000 blocks: 83,999,999.9076 LTC, short by 0.0924 LTC. The leftover Bitcoin comment in GetBlockSubsidy still says “every 210,000 blocks”; the parameter is 840,000. Fees go to miners.

Litecoin uses a UTXO model like Bitcoin. Payments spend previous outputs.

Faster blocks do not mean instant finality. Confirmations still matter for large payments.

Litecoin is Scrypt-only (GetPoWHash → scrypt_1024_1_1_256). Dual-algorithm is not AuxPoW. Dogecoin Core 1.8 introduced AuxPoW so Dogecoin miners can submit Litecoin work as work on the Dogecoin chain. That does not make LTC and DOGE the same asset, and it does not make Litecoin merge-mined.

A payment, in order

A wallet signs an LTC payment.
Nodes check the inputs and relay valid transactions.
Scrypt miners compete for the next block.
Nodes accept the most-work valid chain under Litecoin’s rules.

Keys, not cookbooks

How you send and hold it

The coins are recorded on the network. The wallet holds the secret that can move them. If someone else has that secret, they can usually move the coins.

A recovery phrase is a list of ordinary words that can rebuild the keys. Nobody who is helping you should need it. A support chat, a giveaway, or a “wallet check” that asks for it is trying to take the coins.

Custodial accounts (an exchange or app that holds the keys for you) can freeze, limit, or lose access. Self-custody gives you control and the full job of backup. Neither choice is magic.

This chapter is not a crime cookbook. It does not teach mixing, tumbling, fake identities, or how to hide funds from a lawful process. It teaches you not to donate your keys to a stranger.

Confirm the service wants native Litecoin, not a wrapped token on another chain. Litecoin bech32 addresses start with ltc1. Bitcoin bech32 addresses start with bc1. They are not interchangeable.

If you use MWEB, both sides must support that route. An unsupported MWEB deposit can strand funds.

Safer habits

Download wallet software only from a site or store listing you found yourself, not from a message.
Write the recovery phrase on paper or another offline backup. Do not photograph it, email it, or type it into a website.
Send a tiny test first. Confirm the network, the asset, and the destination.
For a company account, turn on a second factor that is not only a text message if you can.
Stop if anyone asks for the phrase, a remote-control app, or a “verification deposit.”

This book does not tell you how to hide funds, evade a law, or defeat an investigation. A wallet lesson is about not losing your own keys—not about becoming invisible.

Read this twice

What can go wrong

Wrong asset

Wrapped LTC on another network is not mainnet Litecoin.

MWEB mismatch

Not every exchange or wallet understands MWEB addresses.

Keys and scams

The same seed-phrase thefts that hit Bitcoin users hit Litecoin users.

Speed stories

A 2.5-minute target is not a guarantee against reorganization or fraud.

United States readers only

Law and tax notes

These notes are for United States readers only. Other countries have different rules.

The Internal Revenue Service treats convertible virtual currency as property for federal tax purposes. That is the starting point in IRS Notice 2014-21. Later IRS pages, including the virtual-currency frequently asked questions, expand on reporting. They do not turn this book into tax advice.

Selling crypto, trading one crypto for another, or using crypto to pay for goods or services can be a taxable event. Receiving crypto as wages, as a trade or business payment, or in some airdrop or hard-fork situations can also create income. See Notice 2014-21 and Revenue Ruling 2019-24 for the IRS’s own words on forks and airdrops.

Keep records: date, amount in U.S. dollars, what you received or spent, and which service or wallet you used. A lost key is not automatically a deductible story you can invent later.

A listing, an exchange product, or a court remark about someone else is not your tax result.

This is not legal or tax advice. Rules change. Read the linked primary pages and talk to a licensed professional about your own facts.

This coin’s extra pages

MWEB (opt-in, not Monero)

LIP-0003: “This LIP introduces opt-in MimbleWimble (MW) as a new transaction format through extension blocks (EB).” Public and private transactions can exist simultaneously. Users peg coins in and out through an integrating transaction (HogEx).

Activation block 2,265,984 was mined 20 May 2022 05:04:16 UTC. The commonly printed “19 May 2022” traces to the author’s pre-announcement estimate “~May 19th,” not the UTC block time. Software: Litecoin Core v0.21.2.

MWEB is not Monero. Monero’s privacy is mandatory on every standard transaction. Three further reasons the equation fails: (1) MWEB coins can be frozen at the consensus layer; (2) MWEB had a supply bug that was exploited; (3) MWEB is a peg, so the transparent chain still sees the peg-in and peg-out.

In March 2026 a validation bug allowed a block producer to make a small MWEB input appear to support a much larger pegout. At height 3,073,882 an attacker pegged out 85,034.47285734 LTC. Litecoin Core v0.21.5.4 (26 April 2026) added a consensus freeze list and a grandfather clause for that exploit block. Current Core carries frozen_mweb_output_ids and mweb_input_metadata_grandfather_blockhash. The freeze is enforced as bad-txns-frozen-mweb-output.

A later, separate soft fork in v0.21.5.6 (2 August 2026) rejects an MWEB block with a kernel that signals a pegout while carrying an empty pegout list, at height 3,154,440. Do not merge that change with the exploit fix; they are different rules.

Wallet and exchange support is uneven. Check both ends before you peg in.

Words used in this book

GLOSSARY

Read these before the check-the-terms pages. A word is only useful if you can say it back in your own words.

Scrypt: The proof-of-work function Litecoin miners use. It is not SHA-256.
Premine: Coins created before or at launch before open public mining. Litecoin’s documented early coins are 150, not zero.
84 million: The designed maximum unit count—not the number that already sits in wallets.
MWEB: Optional MimbleWimble Extension Blocks. Not Monero. Has a consensus freeze list after the March 2026 inflation exploit.
Halving: A scheduled cut in the block subsidy, every 840,000 Litecoin blocks. The leftover comment in GetBlockSubsidy still says 210,000.
ltc1: Litecoin’s bech32 address prefix. Bitcoin’s is bc1. Do not mix them.
AuxPoW: Dogecoin’s mechanism to accept another coin’s proof of work. Not a Litecoin consensus feature.
Frozen MWEB output: An MWEB output ID that current Litecoin Core will not spend. Added April 2026 after 85,034.47285734 LTC was pegged out through a malicious input.
UTXO: An unspent output a later payment can spend.
Node: Software that checks Litecoin’s rules.
Wrapped LTC: A representation on another chain. Different asset, different risks.
