The Solvable Paradox — Part 2
A new consensus approach: True Proof of Work, reviewer-driven validation, and reputation scoring without buying power.
The Solvable Paradox — Part 1
Known blockchain issues: energy waste, creeping centralisation, and how incentives turned a peer-to-peer dream into a winner-takes-all race.
Gamification and Rewards in Decentralised Crowdsourcing
Transcript on using gamification, reviewers, and a reward-pool model to power a reputation system.
Is Blockchain a Database?
Both store data, but blockchains trade speed and flexibility for auditability, immutability, and shared control.
Proof-of-Work vs. Proof-of-Stake
How PoW and PoS secure blockchains, what they trade, and why “energy vs. capital” is only part of the story.
The Byzantine Generals Problem
Why distributed systems need to agree despite bad actors, and how PoW/PoS tackle it.
Cryptocurrency Mining
Why miners burn energy to secure proof-of-work networks, how rewards work, and where centralization risks creep in.
What is Consensus in the Blockchain?
How decentralized networks agree on one history, why forks happen, and what makes edits loud and expensive.
Digital Cash in the Pre-Bitcoin Period
From DigiCash to e-gold to b-money—why early attempts failed on trust and central points of failure.
What is a Wallet?
Keys, seed phrases, hot vs. cold storage, and why a wallet is really your control panel—not where coins live.
What are Altcoins?
Everything that isn’t Bitcoin: utility tokens, security tokens, and NFTs—and why “cheap” doesn’t mean small.
What is a 'Block' in Blockchain?
How blocks bundle transactions, link by hashes, and why the Genesis block anchors every chain.
Who is Satoshi Nakamoto?
A short history of the pseudonym behind Bitcoin, and why the mystery matters.
What is a Distributed Ledger?
Why ledgers went from clay to code, and how shared databases keep everyone on the same page.
Different Blockchains
Public vs. private, permissioned vs. permissionless—how access and validation shape trade-offs.
Trustless Transactions
How blockchains swap gatekeepers for math, signatures, and shared receipts.
Supply and Market Cap
Why tiny prices can hide huge valuations, and how supply shapes the story.
What is a Block Explorer?
A plain-English tour of blockchain explorers: what they show, why they matter, and how to use them.
The Double-Spend Problem
Why digital cash was fragile before Nakamoto consensus, and how proof-of-work makes edits expensive.
What is Bitcoin?
A plain-English primer on Bitcoin’s origin, supply cap, and why the chain is just a ledger with incentives.
