In 2013, a paper I contributed to offered a solution to the ever
   growing blockchain delema: a finite epoch. The solution is similar the
   one Chaum used on Digicash. It would fix, temporally,  the blockchain
   to include only transactions for the past 2 years, for example, thus
   creating a blockchain of tractable and predictable size for affordable
   full nodes.

   More recently, I've co-written a paper proposing a distributed service
   solution that could solve thin wallet privacy and security issues
   without needing to trust individual full nodes under the control of
   others.

             as you know grarpamp (or maybe you dont know?) the size of
     bitcoins ledger is ~200 gbytes at the moment.  So one wonders how
     big it would get if bitcoin was used for small payments by many
     people (let alone so called micropayments). Seems like very few
     people would be able to run a validating node then?
             oh and yes, 'satoshi' himself dismissed the problem saying
     something like "put a few servers in a (NSA) datacenter"  - but even
     though 'satoshi' said that it remains a bad solution no?
