Introduction to Digital AssetsLocked: included in All Access

How distributed ledgers and blockchains work (consensus, proof of work versus proof of stake, permissioned versus permissionless networks, smart contracts and tokenization), the main kinds of digital assets, how they differ from traditional financial assets, the direct and indirect ways to invest in them, and what drives their return, risk and diversification value.

1. 1. Distributed ledgers, blockchains and their financial usesA distributed ledger is one shared database that every participant holds a matching copy of; a consensus mechanism and cryptography keep it accurate, which can make record keeping, ownership transfer and post-trade processing faster and more transparent, at the cost of energy use and some security and privacy risk.Locked: included in All Access13 min
2. 2. Proof of work, proof of stake and network typesA consensus protocol decides how blocks join the chain: proof of work makes miners spend computing power to win the right, proof of stake makes validators pledge assets, both reward validation with new digital assets, and the network itself can be open to all (permissionless) or restricted (permissioned).Locked: included in All Access13 min
3. 3. Types of digital assets: cryptocurrencies and tokensDigital assets split into cryptocurrencies (Bitcoin, altcoins such as Ether, stablecoins and meme coins, plus central bank digital currencies) and tokens built on existing blockchains (NFTs, security tokens, utility tokens and governance tokens), each with a different purpose and risk.Locked: included in All Access15 min
4. 4. Digital assets versus traditional financial assetsDigital assets differ from traditional assets in four ways: they have no cash flows to anchor their value, they are recorded on decentralised ledgers rather than by central intermediaries, they are rarely accepted as money, and their legal and regulatory protection is weak and unsettled.Locked: included in All Access12 min
5. 5. Direct investment: wallets, exchanges and their risksBuying digital assets directly means holding them in a wallet and trading on centralised or decentralised exchanges, which are largely unregulated; direct holders face fraud (pump and dump, Ponzi schemes, scam ICOs, theft), lost-key risk and manipulation by large holders called whales.Locked: included in All Access13 min
6. 6. Indirect vehicles, asset-backed tokens and DeFiInvestors can gain exposure without a wallet through coin trusts, futures, ETFs, crypto-related stocks and hedge funds, each with its own costs and tracking quality; separately, asset-backed tokens put real assets on a blockchain, and DeFi builds financial services from smart-contract applications.Locked: included in All Access14 min
7. 7. Risk, return and diversification of digital assetsCryptocurrencies earn returns only through price appreciation driven by demand for a limited supply; history shows high returns, very high volatility, deep drawdowns and low correlations with traditional assets, so a small allocation may diversify a portfolio, although correlations have risen, especially in stressed markets.Locked: included in All Access14 min
