I assume Steem will largly be based on graphene...
Has a sharedrop (on bts) been discussed before?
The following parts of Steem reuse code from BitShares which was released under public domain shortly after Graphene was announced.
libraries/net - P2P network code is 100% the same
libraries/db - general purpose, blockchain agnostic, in-memory database
The following parts of Steem have been completely written from scratch:
libraries/chain
- all operations used by the blockchain (transfer, etc)
- all objects kept in memory
libraries/wallet
programs/cli_wallet
The following parts of Steem have been heavily adapted from BTS:
- limit order operation and matching
The question of a share drop has been discussed internally and so far has been avoided for regulatory, support, and complexity reasons.
The current license of Steem prohibits unauthorized chains derived from the same code.
Ned will respond with a more detailed response and policy. I just wanted to provide some 'facts' and not state any position one way or another on the decision to share drop or not.
