So it’s Zapturday and with so many zaps flying around I’ve decided to move some sats around LN too. But let’s make it educational:

The first three people to arrange these discoveries in correct chronological order will get zapped 2100 sats:

• Bit gold by Nic Szabo

• Ecash by David Chaum

• RPOW by Hal Finney

• Hashcash by Adam Back

You’ve got 30 minutes.

I’ll come back with the results at 07:30 UTC
