Like Bitcoin, Cardano uses a UTXO ledger model, though it is an extended version (EUTXO) [23] [24] to facilitate smart contracts and scripting languages. [25] Cardano uses a proof-of-stake (PoS) protocol named Ouroboros; [26] this was in contrast to Bitcoin and Ethereum, which used proof-of-work protocols (though the latter switched over in ...
Ouroboros BFT was an interim version used in 2020 to enable the switch between the Classic and Praos versions of Cardano using a hard fork combinator [7] that preserved the blockchain history; [8] [non-primary source needed] [9] Ouroboros Praos (2017) [10] provided security against fully-adaptive corruption in the semi-synchronous model. At ...

The musical theory of chords is reviewed, to provide terminology for a discussion of guitar chords. Three kinds of chords, which are emphasized in introductions to guitar-playing, [10] [d] are discussed. These basic chords arise in chord-triples that are conventional in Western music, triples that are called three-chord progressions.
Diminished seventh chords may also be rooted on scale degrees other than the leading-tone, either as secondary function chords temporarily borrowed from other keys, or as appoggiatura chords: a chord rooted on the raised second scale degree (D ♯ –F ♯ –A–C in the key of C) acts as an appoggiatura to the tonic (C major) chord, and one ...
The term "chord chart" can also describe a plain ASCII text, digital representation of a lyric sheet where chord symbols are placed above the syllables of the lyrics where the performer should change chords. [6] Continuing with the Amazing Grace example, a "chords over lyrics" version of the chord chart could be represented as follows:
[12] In jazz, 7 ♯ 9 chords, along with 7 ♭ 9 chords, are often employed as the dominant chord in a minor ii–V–I turnaround. For example, a ii–V–I in C minor could be played as: Dm 7 ♭ 5 – G 7 ♯ 9 – Cm 7. The 7 ♯ 9 represents a major divergence from the world of tertian chord theory, where chords are stacks of major and ...
The destination of a chord progression is known as a cadence, or two chords that signify the end or prolongation of a musical phrase. The most conclusive and resolving cadences return to the tonic or I chord; following the circle of fifths , the most suitable chord to precede the I chord is a V chord.
