Satoshi Nakamoto moves his 6.5 yr old bitcoins (opens in new tab)

Go to:

https://blockchain.info/en/address/12c6DSiU4Rq3P4ZxziKxzrL5L...

Scroll down to the bottom, where you will see:

https://blockchain.info/tx/0e3e2357e806b6cdb1f70b54c3a3a17b6...

That is the genesis block.

(Well, OK, that's the transaction contained in the genesis block. The Genesis block itself is https://blockchain.info/block-index/14850)

> Also how do you know it is Sataoshi's?

Because he was the only one mining when bitcoin launched.

If it's just 15k, it's not a biggie, apart from the news that he's alive (or at least, that somebody has control of some of his wallets).

Technically, we do not know that, we can only assume it.

There is no evidence that the person or persons known as Satoshi have ever mined coins on the mainnet.

Does this ledger ever get rolled up? I thought something like that was part of the system. Otherwise you'd have an ever growing transaction log and the system would fail eventually, wouldn't it?

I specifically addressed this misunderstanding in this talk: https://www.youtube.com/watch?v=Twynh6xIKUcat 38:48 while explaining this work: https://people.xiph.org/~greg/confidential_values.txt

You can think of it this way: When you sign a message you prove knoweldge of a private key (discrete log of a particular public key). Everyone can verify the signature, and yet they do not learn anything about the private key they didn't know before seeing the signature.

There is no conflict between verifyability and privacy.

It seems plausible that fully homomorphic encryption will eventually enable a practical and fully anonymous cryptocurrency, but nobody has figured out how yet. Also, even without FHE, maybe someone will figure out how to make a Bitcoin-style public-ledger system that somehow uses Chaumian blinded keys instead of ditching anonymity entirely.

(I know, I just wish I didn't)
