I need to use BitcoinJ to create and host wallet on my own website. However, it keeps downloading blocks and the sync seems taking forever. I need to be able to create a wallet within a few seconds.
Could anyone please advice what should i do to optimize the sync time?
ECKey key = new ECKey();
Address addressFromKey = key.toAddress(params);
Wallet wallet = new Wallet(params);
wallet.importKey(key);
File blockFile = new File(“/tmp/bitcoinblocks”);
BlockStore blockStore = new MemoryBlockStore(params);
BlockChain chain = new BlockChain(params,blockStore);
PeerGroup peerGroup = new PeerGroup(params, chain);
peerGroup.addPeerDiscovery(new DnsDiscovery(params));
peerGroup.addWallet(wallet);
peerGroup.start();
peerGroup.downloadedBlockChain();
