Who is allowed to write the ledger

A public chain needs a rule for who may add the next . Bitcoin uses proof of work: machines spend energy to win the right. Ethereum now uses proof of stake: coin that is locked can earn the right. Both are ways to make lying expensive.

We’ll open this slide when you come back. This device remembers it.

Swipe the deck. Hold Previous for slide one. A vertical swipe still scrolls the page.

A public chain needs a rule for who may add the next . Bitcoin uses proof of work: machines spend energy to win the right. Ethereum now uses proof of stake: coin that is locked can earn the right. Both are ways to make lying expensive.

You do not need to run a to learn. You do need to know that “the chain said so” is only as strong as those rules and the people who follow them. Forks happen. Tickers can split. History can be messy.

A classroom is not a . Six coins of waiting on a live network is not a thing we simulate. Live deposits can still reverse if an exchange credits you early.

LOOK DON'T BUY

Real World Markets is a classroom. We only teach — stocks, crypto, and how markets work. You can look at delayed last. You cannot buy here. We do not take orders or hold money. Not a broker. Not a CASP. Lessons are free.

Delayed public last when the feed is up — a number to look at, never a ticket. Paper results are hypothetical and have no cash value. Not a broker-dealer. Not a CASP or money transmitter. You cannot buy here.

Passing a quiz is not a qualification or a license. The Professor will not tell you what to buy. Company names and tickers belong to their owners. We draw letter marks, not official logos. Not affiliated with Apple, Nasdaq, S&P, Yahoo, CoinGecko, or CoinMarketCap.

This classroom does not give financial advice. We do not tell you what to buy, sell, or hold. A lesson, delayed last, a paper fill, a quiz, Professor Moon, and a quote on the tree are teaching — not a recommendation, not a personalized plan, and not a reason to place a live order. We only teach. Educational classroom only. Not a seller. Not a market we operate. Not investment advice, not legal advice, not an offer to buy or sell, not a broker-dealer, investment adviser, CTA, or CIRO/CSA registrant. Not a CASP, VASP, MSB, money transmitter, or gambling operator. We do not custody, exchange, or transmit crypto-assets. We do not file a license for you. Not registered with the U.S. SEC, FINRA, CFTC, NFA, FinCEN, Canada’s CSA/CIRO, or Mexico’s CNBV. Last may be a delayed public print when the feed is up, or a teaching path if it is not — never a reason to trade. Options premiums and NFT floors are teaching numbers. Paper results are hypothetical and have no cash value. World Circuit is a paper board game, not gambling and not a live market. Past or simulated performance is not indicative of future results. CFTC Rule 4.41. Third-party names stay with their owners. Letter marks, not official logos.
