Differences between Kheavyhash, Blake3 and BlockDAG

Hello.

Can anyone tell about the main differences between Kheavyhash, Blake3 and BlockDAG ?

I understand Kheavyhash is an algorithm designed to provide robust security for transactions and protect data within blockchain networks;

Blake3, an algorithm designed to be fast, secure, and versatile.

BlockDAG, an algorithm inspired by Bitcoin and Kaspa that delivers industry-leading speeds, high security, and high decentralization; built to power everyday applications to enterprise-grade DeFi protocols and with the power to mine from anywhere.

And that they are all three decentralized and ‘Proof of work’ consensus. Is that right?

Can these algorithms / blockchains be complementary / interconnected ?

How do these blockchains differ from what I stated above?

Thanks for your insights :)

Best regards.
