Wavelet coherence plots as above highlight areas in the time-frequency space where the two series co-move. The warmer the colour, the higher the coherence (which can be interpreted as correlation) at that location in the time-frequency space; the colours used in this work range from dark blue (0, no coherence) to yellow (1, strong coherence). Statistically significant areas of coherence are surrounded by a thick black line.

Cryptocurrency transactions are recorded on a decentralized ledger. This ledger is called a blockchain. Every time crypto is bought or sold, the transaction is added to the blockchain — a public database of the transactions, which is available to other crypto holders. Anyone can join and participate in the blockchain, but data on individual transactions — and the people involved with them — are secured using cryptography (the basis for the term cryptocurrency). For each transaction added to the blockchain, there’s a digital validation process to verify it and prevent fraud.
