What does it mean?

1. The Message

{md5 => 4d1ad2d7111a3d204166cc9efd42394d, owner => BTC:1HZwkjkeaoZfTSaJxDw6aKkxp45agDiEzN, inputtx => FirstIssue, previousowner => BTC:1HZwkjkeaoZfTSaJxDw6aKkxp45agDiEzN, idop => DY1}

transfers the ownerhip of the asset with md5

4d1ad2d7111a3d204166cc9efd42394d

from the owner

BTC:1HZwkjkeaoZfTSaJxDw6aKkxp45agDiEzN

to the owner

BTC:1HZwkjkeaoZfTSaJxDw6aKkxp45agDiEzN

2. This Message is signed by the Previous Owner with the private key corresponding to

BTC:1HZwkjkeaoZfTSaJxDw6aKkxp45agDiEzN

because only the Previous Owner can transfer the asset to a New Owner
3. Everyone can check the Previous Owner Sign

HN+wXK3QTJ3nS3xR1NB2vp4gwUyqgZgEirrtGzTLQCPXu+B6nuCXQg5tJiOe9f4/T0849Xe6lLZhVQ4DEtObiWQ=

against the Message and the address

BTC:1HZwkjkeaoZfTSaJxDw6aKkxp45agDiEzN

4. Then the previous owner sign is appended to the message obtaining the new message

{{md5 => 4d1ad2d7111a3d204166cc9efd42394d, owner => BTC:1HZwkjkeaoZfTSaJxDw6aKkxp45agDiEzN, inputtx => FirstIssue, previousowner => BTC:1HZwkjkeaoZfTSaJxDw6aKkxp45agDiEzN, idop => DY1}, prevownersign => HN+wXK3QTJ3nS3xR1NB2vp4gwUyqgZgEirrtGzTLQCPXu+B6nuCXQg5tJiOe9f4/T0849Xe6lLZhVQ4DEtObiWQ=}

5.This new message is signed By Bytestamp with the private key corresponding to the DTC address D8GafEsbyssg4TQN71KTbd8QdRg846MxCQ , that is on ByteStamp Web Site and also saved in the Datacoin Blockchain in transaction 78c8b327930ec9ec4e280801e2ebba190add5bcbeca295dba9992d5e2cb455bb
6. Then the Bytestamp sign

IPLET9JLI0F4h9lF1nG8sILruoHndAZM5VVoOBelDl1kldrPGmBXlR9LWBoqshmR9Mc1xMtwbtYCHdBsoHDLpvU=

is appended to the message togheter with the Hash of the Previous Transaction containing a data Asset:

0055177b8655f1b6daca02f134f7d10b
7.So we have a new message

{{{{md5 => 4d1ad2d7111a3d204166cc9efd42394d, owner => BTC:1HZwkjkeaoZfTSaJxDw6aKkxp45agDiEzN, inputtx => FirstIssue, previousowner => BTC:1HZwkjkeaoZfTSaJxDw6aKkxp45agDiEzN, idop => DY1}, prevownersign => HN+wXK3QTJ3nS3xR1NB2vp4gwUyqgZgEirrtGzTLQCPXu+B6nuCXQg5tJiOe9f4/T0849Xe6lLZhVQ4DEtObiWQ=}, bytestampsign => IPLET9JLI0F4h9lF1nG8sILruoHndAZM5VVoOBelDl1kldrPGmBXlR9LWBoqshmR9Mc1xMtwbtYCHdBsoHDLpvU=}, prevhash => 0055177b8655f1b6daca02f134f7d10b}

on which is calculated an hash, just as a blockchain works (hashcash)
8. This hash

2e694f4c5be66a6fea312334d05ca1a3

is appended to the Message and we have the final Message

ASSET:{{{{{md5 => 4d1ad2d7111a3d204166cc9efd42394d, owner => BTC:1HZwkjkeaoZfTSaJxDw6aKkxp45agDiEzN, inputtx => FirstIssue, previousowner => BTC:1HZwkjkeaoZfTSaJxDw6aKkxp45agDiEzN, idop => DY1}, prevownersign => HN+wXK3QTJ3nS3xR1NB2vp4gwUyqgZgEirrtGzTLQCPXu+B6nuCXQg5tJiOe9f4/T0849Xe6lLZhVQ4DEtObiWQ=}, bytestampsign => IPLET9JLI0F4h9lF1nG8sILruoHndAZM5VVoOBelDl1kldrPGmBXlR9LWBoqshmR9Mc1xMtwbtYCHdBsoHDLpvU=}, prevhash => 0055177b8655f1b6daca02f134f7d10b}, hash => 2e694f4c5be66a6fea312334d05ca1a3}

with the initial tag

ASSET:

which identifies the data as an Asset transaction
9. This final Message is stored in the Datacoin BlockChain, so nobody can change an ownership transfer once it happened.
