As an outsider not paying too much attention, how do you beat the ledger problem? Crypto only works if there is a ledger. I don't want a ledger of every transaction I made. Seems like an insurmountable fundamental privacy issue.

Ethereum based research projects are addressing this. There is a currently active and usable project called Railgun which allows for hidden balances and transactions. Aztec network is launching soon which is a fully private L2 chain. It has taken a really long time but it seems the next few years will bring real privacy.

Monero solved it

Framing the ledger as the problem seems strange. It's more accurately the solution. The problem being how you transfer value through the internet in a trusted manner.

Re: privacy though, there's many solutions. Single tailored chains for privacy, mixers, encrypted tokens, permissioned chains, etc.

In my experience, privacy, while important, is not something users actually care about enough to demand a solution for. Most web3 users today just want to degen and gamble, and they're okay with KYC to do so.

There are plenty of solutions to this problem. See eg the Zerocash paper and the Zcash chain, both decade+ old now
