From the last link:

     1. Write spam script using an HD wallet (easy with Electrum daemon). Mimic natural txs with random values and fees within chosen constraints.
     2. Make a deal with 1 or more miners to refund fees on spam txs. Give miner the wallet xpub and a script to sum tx fees in their own blocks.
     3. ...
     4. Push political agenda while LOL.

I'd say, this week turned into something really interesting!

## Ethereum

While Bitcoin struggles with "the load" (where ever it comes from), our friends
at Ethereum had a successful hard fork this week but today ran into unintended
forks due to implementation differences:

### Update - Thu Nov 24 17:41:10 CET 2016

Ethereum probably needs to **rollback**:

## Steem

[Major changes upcoming here aswell, though intended and heavily discussed
changes with the option for shareholders to deny the hard fork.](https://steemit.com/steem/@steemitblog/final-review-of-steem-economic-changes)

## BitShares

Nothing really going on, except for the first blockchain to reach 10MM blocks (11MM by now) :)
