See https://github.com/bitcoin/bitcoin/blob/master/doc/build-unix.md for notes on dependencies that must be installed before beginning.
To run alphad:
1. Download/build bitcoind/alphad
bash git clone https://github.com/ElementsProject/elements cd elements git checkout bitcoin ./autogen.sh && ./configure && make mv src/bitcoin{d,-cli,-tx} ../ git checkout alpha ./autogen.sh && ./configure && make mv src/alpha{d,-cli,-tx} ../ cd ..
2. Run bitcoind/alphad
bash RPC_USER=user RPC_PASS=pass ./bitcoind -rpcuser=$RPC_USER -rpcpassword=$RPC_PASS -testnet -txindex -daemon ./alphad -rpcuser=$RPC_USER -rpcpassword=$RPC_PASS -testnet -rpcconnect=127.0.0.1 -rpcconnectport=18332 -tracksidechain=all -txindex -blindtrust=true -daemon
Note that once bitcoind finishes syncing, you can set -blindtrust=false to check that transfers to Elements Alpha are from confirmed bitcoin blocks.
To move money into Elements Alpha:
1. See 1 and 2 in "To run alphad"
2. Download secp256k1:
bash git clone https://github.com/bitcoin/secp256k1 cd secp256k1 ./autogen.sh && ./configure --with-bignum=no && make make DESTDIR=`pwd`/install install cd ..
3. Download contracthashtool
bash git clone https://github.com/blockstream/contracthashtool cd contracthashtool make CXXFLAGS="-I../secp256k1/install/usr/local/include -L../secp256k1/install/usr/local/lib -static" cd ..
4. Download python-bitcoinrpc
bash git clone https://github.com/jgarzik/python-bitcoinrpc
5. Use sidechain-manipulation.py:
```bash

To move money back out of Elements Alpha: 1. See 1-4 of above. 4. Use sidechain-manipulation.py: ```bash [matt@2ca87f82dd9a bitcoin]$ cd elements [matt@2ca87f82dd9a bitcoin]$ ./contrib/sidechain-manipulation.py generate-one-of-one-multisig mainchain-wallet One-of-one address: mm8UW9YsjeHoVhXbHG4hEFKJt52P5iB7Vi P2SH address: 2MzqiCCUwtKKEV9Kxiyvk8ZuNCFKbcbneva [matt@2ca87f82dd9a bitcoin]$ ./contrib/sidechain-manipulation.py send-to-mainchain 2MzqiCCUwtKKEV9Kxiyvk8ZuNCFKbcbneva 1
To run a fedpeg operator (for your own sidechain): 1. See 1 and 2 in "To run alphad" (Do not forget to append -blindtrust=false to the alphad command args once bitcoin syncs!) 2. See 2-4 of "To move money into Elements Alpha" Note that the bitcoind/sidechaind wallets must be EMPTY of keys/transactions except for those created automatically by fedpeg scripts 3. Install python ZeroMQ. 4. Ensure your clock is reasonably accurate (within a second should suffice) 5. Edit bitcoin/contrib/fedpeg/constants.py with the neccessary information 6. As a daemon/in screen/etc, run both bitcoin/contrib/fedpeg/withdrawwatch.py and bitcoin/contrib/fedpeg/blocksign.py
