This is all you have to do? There is no way anyone will have a problem with this method. /s

The instructions do not give you all the files you need. One way is to clone the repository. I have a sample maybe by for Monday so you can do this in the web wallet instead.

Much needed, thanks!!

...backup your original key file as it contains all your keys.

This is from Step 1: https://www.dropbox.com/s/jw0r603u1klm7s5/bloom.dat
The sha1 sum will print when you run step two... It should print:

Code: [Select]

bloom.dat (1048576 bytes) sha1 3cee441d8d28ab3b26aea149630fa2a96a91845c

Thanks to awesome work by theoretical and jcalfee we now have two simple command line tools that will remove keys that are not in the Bitshares 2 genesis file from your keys json file generated by the wallet_export_keys command. I've just tested it on a wallet with 95k keys (16MB) and it was reduced to 375 keys (64kB). This might get embedded in the Bitshares 2 wallet and in a future 0.9.4 release of legacy Bitshares, but I wanted to share it with those of you who are struggling with importing your keys.

DISCLAIMER: try at your own risk, I'm not responsible for any loss of keys or balances, etc. Instructions are for *nix/OSX
DISCAIMER 2: Please backup and keep safe your original keys file first

The tools were written using Python and Nodejs so you'll need those installed.

Step 1: Generate a bloom filter file from Bitshares 2 genesis file

• Create a new folder somewhere to keep all the files you will download
• Download the genesis file from github: https://raw.githubusercontent.com/bitshares/bitshares-2/bitshares/genesis.json
• Download the bloom filter script: https://raw.githubusercontent.com/bitshares/bitshares-2/bitshares/programs/genesis_util/create_bloom_filter.py
• Run the script using the following command

Code: [Select]

python create_bloom_filter.py -i ./genesis.json --o bloom.dat
Step 2: Filter your old wallet.json using the bloom filter

• Clone the graphene-ui repo: "git clone https://github.com/cryptonomex/graphene-ui.git"
• In a terminal, go inside the cloned repo: "cd graphene-ui/dl/" and install dependencies "npm install"
• Copy the bloom.dat file you generated as well as your wallet.json file to "graphene-ui/dl/programs"
• From inside the folder "graphene-ui/dl/programs", apply the filter to your wallet.json using:

Code: [Select]

cat OLD_WALLET_NAME.json | node ./bloom_filter_wallet.js > NEW_WALLET_NAME.json
The script will run, telling you as it goes how many keys it's removed and has processed.

Step 3: Profit
Once that's done, you should have a MUCH smaller json file containing the keys you need to import in the Bitshares 2.0 wallet of your choice, light wallet, OpenLedger, localhost, etc.
