...gee, you like simple questions, Jutta :-)

For info of any of us who might be shy to say 'what's a blockchain again?'

Techopedia explains Blockchain

The block chain ledger helps to provide transparency for transactions.
Although many bitcoin transactions are in some ways anonymous, the block
chain ledger can link individuals and companies to bitcoin purchases and
ownership by allowing individual parties, called miners, to process
payments and verify transactions. Rather than a central company presiding
over the use of bitcoin, these block chain originators serve central roles
in the management and administration of this alternative currency system.
