Cryptocurrencies
Blockchain, bitcoin issuance, halving, stablecoins and custody.
A blockchain is a distributed ledger of transactions kept by many independent participants in the network.
Bitcoin issuance is capped at 21 million coins. Roughly every four years (every 210,000 blocks) the reward to miners is halved — this is the halving.
Stablecoins are pegged to another asset, most often the dollar. Their reliability depends on real backing. Access to crypto assets is given by private keys.
