Solving real-world problems with distributed ledger technology
summary
Explains concrete DLT properties: a shared ledger with decentralized copies, deterministic smart contracts, and transparency; cites limits like 15 TPS on Ethereum and finality delays (about 60 minutes finality on Bitcoin, ~6 minutes on Ethereum, ~720 minutes on some delegated‑PoS chains). Mentions tooling and platforms (Ethereum, IOTA, Hashgraph, Aura), oracles for external data, a seven‑GPU Zcash mining rig anecdote, $150–175k salaries for blockchain engineers, and real deployments such as Guts ticketing that constrain resale and appears to work.
