Skip to content Yesterday I wanted to see how some of my Bitcoins were doing.I use Multibit HD 0.4.1.Suddenly MultibitHD showed the whole wallet being unconfirmed.That means that I couldn’t send any Bitcoins or that Multibit HD has lost its bookkeeping.I find this unacceptable.Who can work with a wallet that can’t do the bookkeeping correctly?So first start to fix the issue and then look for a better wallet.I tried to repair the wallet several times but only a part would become confirmed.So, I still couldn’t get at my money.Even restoring from the seed didn’t help.When you look at the issue tracker on Github, you see that a lot more people have issues.Especially the closed issue tracker, leaves people in the dust without their money.These issues have been popping up since October 2016 and I haven’t seen a warning since.A wallet project should do a good disclosure on any bugs it finds and issue a recommendation to stop using the wallet until the issue is found and dealt with.

/keepkey/multibit-hd/issues I was able to extract my bitcoins by downgrading to Multibit 0.1.1 and do a repair of my wallet.I became skeptical after the Multibit people sold the software to KeepKey.Also I needed to repair my wallet last year, which also scared the bejeezus out of me.Any project that produces a wallet that has a big button called “repair” shoudl do a better job.Those worries are now confirmed.Now getting the heck out of here towards a more sane client like electrum.Photo: used and modified under Creative Commons license thanks to BTCKeychain_ Here's how it works: Anybody can ask a question Anybody can answer The best answers are voted up and rise to the top up vote down vote favorite 3 -rescan is a command line argument that is passed to the bitcoin client after restoring wallet.dat from backup.Which files get recalculated?Which files does the rescan command read?Why is it a good practice to first download all the blocks, then rescan, and not the other way around?

(as a comment on this answer suggests) bitcoin-core rescan up vote down vote The bitcoin client stores, in the wallet, the transactions that affect coins it manages.If it sees a new transaction, it checks to see if that transaction affects any accounts stored in the wallet.If so, the wallet is updated.Similarly, if the chain is reorganized, the wallet is updated.However, the client doesn't check to make sure the wallet is synchronized to the current block chain.To fix this, the rescan command can be used.This causes the client, on startup, to go through every single block it has downloaded, search for transactions affecting accounts in the wallet, and update the wallet's transaction store and balances to reflect that transaction.There are a few cases when you definitely need to rescan.For example: If you restore a backed up wallet, it will be missing any transactions in blocks you downloaded after you backed up the wallet.Since the client won't receive those blocks (since it already has them) the normal wallet update logic won't fix this.

Instructions To Install the plugin and connect it to a Bitcoin full node using the built-in Bitcoin adapter: Make sure that you have the latest WordPress version installed, and that you are running on at least PHP 5.6.Even though the plugin has been tested on WordPress 4.0 and PHP 5.3, for security reasons you are strongly recommended to use the latest version of WordPress and a supported version of PHP.Check to see here if your PHP version is currently supported for security issues.As of 2017, anything below 5.6 has reached its end-of-life and is no longer supported.Install and activate the Wallets plugin.For general information on installing WordPress plugins, you can consult the relevant WordPress documentation.Install a Bitcoin full node on your server.Detailed instructions are available here.Read and follow the instructions carefully.Take note of the memory, disk, and bandwidth requirements and check against the resources available on your server.

If you find that running a full node is too heavy on your server’s resources, please see the FAQ section below for alternative options.Configure the bitcoin adapter on your WordPress installation.Navigate to Wallets → Bitcoin (BTC) in your WordPress admin area.At a minimum you need to enable the adapter and enter the location and credentials to your Bitcoin daemon RPC API.You will need to set the following: IP, Port, User, Password, Path.Configure the bitcoin daemon on your server.You will need to edit your ~/.bitcoin/bitcoin.conf file and make the configuration match what you entered above.The plugin will give you the exact configuration arguments that you need to start the daemon with.For more information on the bitcoin daemon configuration, consult the relevant wiki page.Check that the adapter works.Navigate to the Wallets menu in the admin area.If the Bitcoin Adapter Status reads Responding, then you’re good to go.Note that for a new bitcoind installation, you might have to wait until the entire blockchain downloads first.

Further reading /Managing_Plugins#Installing_Plugins /en/full-node https://en.bitcoin.it/wiki/Running_Bitcoin Is it secure?The Bitcoin and Altcoin Wallets plugin is only as secure as your WordPress installation.Regardless of whether you choose to install this plugin, you should have already taken steps to secure your WordPress installation.At a minimum you should do the following: Install a security plugin such as Wordfence.Read the Codex resources on Hardening WordPress.If you are connecting to an RPC API on a different machine than that of your WordPress server over an untrusted network, make sure to tunnel your connection via ssh or stunnel.Do I really need to run a full node?bitcoind is too resource-hungry for my server.Running a full node requires the full blockchain to be downloaded and is best for people who are able to administer a server.Remember that a copy of the blockchain can take tens of GigaBytes on your server, so check your available disk and network resources first.

You currently have the following alternative options: 1.Use the block.io Cloud Wallet Adapter extension 2.Use the CoinPayments Adapter extension 3.Install and configure the bittiraha-walletd wallet.Point your RPC API settings to that wallet.This is a wallet based on bitcoinj and does not store the blockchain locally.How can I integrate the Bitcoin and Altcoin Wallets plugin with my site’s frontend?A number of UI elements are made available for the front-end.Just use the provided widgets in your theme, or insert the following shortcodes in a post or page: deposit funds: wallets_deposit, withdraw funds: wallets_withdraw, transfer funds to other users: wallets_move, view their balance: wallets_balance, view past transactions: wallets_transactions.These shortcodes render knockout.js-enabled forms.The forms only show to users who have the necessary capabilities assigned.I don’t like the built-in forms.Can I provide my own?First of all, the forms can be styled with CSS.

They have convenient HTML classes that you can use.If you wish to create forms with completely different markup, you can provide your own views for these shortcodes.Use the wallets_views_dir filter to override the directory where the views are stored (the default is wallets/includes/views).Most people will not need to do this.I want to do transactions from JavaScript.I don’t want to use the provided shortcodes and their associated forms.The provided built-in forms talk to a JSON API that is available to logged in users.If you choose to build your own front-end UI, you can point your AJAX calls directly to the JSON API.I want to do transactions from the PHP code of my theme or plugin.You can use the PHP API directly.Refer to the documentation for details.How are fees calculated?As a site administrator you set two types of fees for each coin adapter that you enable: transfer fees — These are the fees a user pays when they send funds to other users.These types of transactions do not go on the blockchain, so any fees you set here are subtracted from the sender’s account in addition to the sent amount.

withdrawal fees — This is the amount that is subtracted from a user’s account in addition to the amount that they send to another address on the blockchain.This is NOT the network fee, and you are advised to set the withdrawal fee to an amount that will cover the network fee of a typical transaction, possibly with some slack that will generate a modest profit on your site.To control network fees when running a Bitcoin full node, use the wallet settings in bitcoin.conf: paytxfee, mintxfee, maxtxfee, etc. Refer to the documentation for details.How can I get support or submit feedback? for all issues and inquiries regarding the plugin.For all other communication, please contact info@dashed-slug.net.Work with many Altcoins Very cool plugin.The best are the coin adapters that you can use different coins.Nice good job Read all 3 reviews “Bitcoin and Altcoin Wallets” is open source software.The following people have contributed to this plugin.dashed-slug Translate “Bitcoin and Altcoin Wallets” into your language.Interested in development?Browse the code or subscribe to the development log by RSS.
