Bitcoin Testnet: A Beginner’s Guide to Using the Bitcoin ...

An Appeal for Clarity about Bitcoin.com's Commitment to Testnet Development

TL;DR - Testnet infrastructure is flaky and, as a developer, this makes development and user experimentation frustrating and more difficult than it should be; does bitcoin.com have an updated "official position" on their commitment to testnet?; I am willing to pay for a reasonable level of reliable infrastructure to whoever can provide it
I appreciate all testnet infrastructure that is in place (mostly provided by bitcoin.com, since that's what I've been using with Bitbox), so thank you very much to bitcoin.com and the community for providing all of that. I also realize and respect that Prod systems are #1 in terms of maintenance priority and that they are not obligated to provide ANY testnet infrastructure, so I appreciate what has been there in the past - please, do not forget that!
I only do part-time BCH development and admittedly am taking a hack-and-slash development/experiment approach to see what works/is cool, which is why I'd rather mitigate my financial risk with TBCH rather than try to come up with a "secure" development/sharing model. I'd also like to make it low risk to demonstrate on a webapp the cool things that OTHER people can do with cryptocurrency, especially over the internet! The testnet faucet could be a great resource for that and I'd really like to be able to keep using that.
However, there have been several periods of sub-optimal software development where the infrastructure is down for days or weeks without explanation or communication (now is one of those periods where tbitdb and TBCH block explorer is down). I've heard (informally, through some developers) that developing on testnet is not a good idea due to these infrastructure issues, but I've also heard from bitcoin.com/some of its folks that testnet infrastructure is something that they support.
I have been assuming I could develop and demonstrate apps on testnet, but this has been getting progressively more difficult. I am willing to develop against mainnet to get the benefits of app ecosystem reliability, but this goes against my better instincts as a software developer for testing purposes. If I want people to "try stuff out" with crypto, I'd also like to be able to give away/leave behind paper wallets with TBCH rather than real BCH (one scales much better than the other!).
I'm hoping I and others in similar situations can get clarity from bitcoin.com about what we should expect in the future with regards to testnet infrastructure support and uptime. Again, I am willing to rethink going to mainnet to do my testing and experimentation, but I feel that's the wrong way to attract new developers to the space. I'd even pay to have access to a reliable testnet environment (explorerest.bitcoin.com/BitDB server) - is this something else other developers would find worthwhile, too?

Testnet Faucet Back Up - Donations Needed!

Hey dev community: the Bitcoin.com testnet faucet is back up and running:
https://developer.bitcoin.com/faucets/bch/

Someone hacked the app over the last couple weeks with an automated script that spoofed IP addresses. I've added additional protection to prevent this from happening again. But the wallet was drained and has less than 100 tBCH in it. We really need testnet BCH donations. Please donate to the faucet address:
bchtest:qqmd9unmhkpx4pkmr6fkrr8rm6y77vckjvqe8aey35

Please pass this around. I know there area few testnet 'whales' that hold a lot of testnet BCH. We could really use their help.

Soo after almost 3 months of setting up I have my own LN full node running on RP3

Soo after almost 3 months of setting up I have my own LN full node running on RP3
I have been eager to try LN mainnet since the very beginning of it. I've found out about lnd, eclair, zap and other wallets but every scenario I tried to use it failed because of critical issues:
  • eclair does not really constitute a wallet, it's more like a credit card - you can send money but not receive it
  • lnd is okay, but requires a server and tons of resources for maintaining a full node, can't be used securely, efficiently and mobily at the same time
  • zap offers some cloud wallet (in testnet!) by default, this is a serious misunderstanding of my cryptoanarchy needs
  • web wallets - ah, forget it
So I've decided to use my Raspberry Pi with a very old laptop HDD attached (200GB so the pruning function has to be used) to create a backend wallet service and zap desktop (temporarily!) as my frontend control panel.
https://preview.redd.it/0vcq147887q11.png?width=1024&format=png&auto=webp&s=7bb6eccdd4110a857e5af0400acc2d7e1ee7ee85
Setting up Pi is easy, lots of tutorials over the internet, not gonna discuss it here. Then I had to obtain bitcoind (current rel: bitcoin-0.17.0-arm-linux-gnueabihf.tar.gz) and lnd (lnd-linux-armv7-v0.5-beta.tar.gz), create a bitcoin technical user, deploy the tools, configure and install new systemd services and go through the configs. This is a tricky part, so let's share:
# Generated by https://jlopp.github.io/bitcoin-core-config-generato # This config should be placed in following path: # ~/.bitcoin/bitcoin.conf # [core] # Set database cache size in megabytes; machines sync faster with a larger cache. Recommend setting as high as possible based upon machine's available RAM. dbcache=100 # Keep at most  unconnectable transactions in memory. maxorphantx=10 # Keep the transaction memory pool below  megabytes. maxmempool=50 # Reduce storage requirements by only storing most recent N MiB of block. This mode is incompatible with -txindex and -rescan. WARNING: Reverting this setting requires re-downloading the entire blockchain. (default: 0 = disable pruning blocks, 1 = allow manual pruning via RPC, greater than 550 = automatically prune blocks to stay under target size in MiB). prune=153600 # [network] # Maintain at most N connections to peers. maxconnections=40 # Use UPnP to map the listening port. upnp=1 # Tries to keep outbound traffic under the given target (in MiB per 24h), 0 = no limit. maxuploadtarget=5000 # [debug] # Log IP Addresses in debug output. logips=1 # [rpc] # Accept public REST requests. rest=1 # [wallet] # Do not load the wallet and disable wallet RPC calls. disablewallet=1 # [zeromq] # Enable publishing of raw block hex to 
. zmqpubrawblock=tcp://127.0.0.1:28332 # Enable publishing of raw transaction hex to
. zmqpubrawtx=tcp://127.0.0.1:28333 # [rpc] # Accept command line and JSON-RPC commands. server=1 # Username and hashed password for JSON-RPC connections. The field comes in the format: :$. RPC clients connect using rpcuser=/rpcpassword= arguments. You can generate this value with the ./share/rpcauth/rpcauth.py script in the Bitcoin Core repository. This option can be specified multiple times. rpcauth=xxx:yyy$zzz
Whooaa, this online config generator is really helpful, but I still had to manually correct a few things. The last line is obviously generated by rpcauth.py, I disabled the wallet functionality as lnd is going to take care of my funds. ZMQ is not available to the network so only my LND can use it, RPC usage I still have to think through a little, in general I would like to have my own block explorer some day but also be safe from any hacking attempts (thus I would need at least 2 RPC ports/user accounts - one for lnd, one for block explorer frontend). No ports open on firewall at this time, only UPnP is active and gently opens 8333 for block/tx transfers.
Now, synchronizing the blockchain took me time from mid-July to early September... The hard drive is really slow, also my external HDD drive has some trouble with its A/C adapter so Pi was getting undervoltage alerts all the time. Luckily, it is just downclocking when it happens and slowly but steadily synchronized the whole history. After all, I'm not paying even $5 monthly for a VPS, it is by design the cheapest hardware I could use to set up my LN wallet.
When bitcoind was ready (I've heard some stories about btcd but I don't trust this software yet, sorry), it's time to configure lnd.conf:
[Application Options] debuglevel=trace rpclisten=0.0.0.0:10009 externalip=X.X.X.X:9735 listen=0.0.0.0:9735 alias=X color=#XXXXXX [Bitcoin] bitcoin.active=1 bitcoin.mainnet=1 bitcoin.node=bitcoind [Bitcoind] bitcoind.rpchost=127.0.0.1 bitcoind.rpcuser=X bitcoind.rpcpass=X bitcoind.zmqpubrawblock=tcp://127.0.0.1:28332 bitcoind.zmqpubrawtx=tcp://127.0.0.1:28333 
Here I've had to XXX a little more fields, as not only the bitcoind RPC credentials are stored here, but also my node's public information (it should be illegal to run nodes without specifically selected color and alias!). It is public (and I had to open port 9735 on my firewall), but not necessarily connected to my reddit account for most of the adversaries, so let's keep it this way. In fact, I also see a security vulnerability here: my whole node's stability depends on the IP being static. I could swap it for a .tk domain but who can tell if the bad guys won't actively fight DNS system in order to prevent global economic revolution? As such, I would rather see node identification in LN based on a public key only with possible *hints* of last-known-ip-address but the whole discovery should be performed by the nodes themself in a p2p manner, obviously preventing malicious actors from poisoning the network in some way. For now, I consider the IP stability a weak link and will probably have to pay extra Bitcoin TX fees when something happens to it (not much of a cost luckily!).

https://preview.redd.it/hjd1nooo77q11.png?width=741&format=png&auto=webp&s=14214fc36e3edf139faade930f4069fc31a3e883
Okay then, lnd is up and running, had to create a wallet and give it a night for getting up to speed. I don't know really what took it so long, I'm not using Windows nor 'localhost' in the config so the issues like #1027 are not the case. But there are others like #1545 still open so I'm not going to ponder much on this. I haven't really got any idea how to automatically unlock the wallet after Pi restart (could happen any time!), especially since I only tried to unlock it locally with lncli (why would I enter the password anywhere outside that host?), but let's say that my wallet will only be as stable as my cheap hardware. That's okay for the beta phase.
Finally, zap-desktop required me to copy tls.cert and admin.macaroon files to my desktop. If my understanding of macaroon (it's like an authentication cookie, that can later be revoked) is correct then it's not an issue, however it would be nice to have a "$50 daily limit" macaroon file in the future too, just to avoid any big issues when my client machine gets stolen. Thanks to this, I can ignore the silly cloud-based modes and have fully-secure environment of my home network being the only link from me to my money.
https://preview.redd.it/11bw3dgw47q11.png?width=836&format=png&auto=webp&s=b7fa7c88d14f22441cbbfc0db036cddfd7ea8424
Aaand there it is. The IP took some time to advertise, I use 1ml.com to see if my node is there. The zap interface (ZapDesktop-linux-amd64-v0.2.2-beta.deb) lacks lots of useful information so I keep learning lncli syntax to get more data about my new peers or the routes offered. The transactions indeed run fast and are ridiculously cheap. I would really love to run Eclair with the same settings but it doesn't seem to support custom lnd (why?). In fact, since all I need is really a lncli wrapper, maybe it will be easy to write my own (seen some web gui which weighs 700MB after downloading all dependencies with npm - SICK!). Zap for iOS alpha test registration is DOWN so I couldn't try it (and I'm not sure if it allows custom lnd selection), Zap for Android doesn't even exist yet... I made a few demo transactions and now I will explore all those fancy t-shirt stores as long as the prices are still in "early investor" mode - I remember times when one could get 0.001 BTC from a faucet...
https://preview.redd.it/42sdyoce57q11.png?width=836&format=png&auto=webp&s=7ec8917eaf8f3329d51ce3e30e455254027de0ee
If you find any of the facts presented by me false, I am happy to find out more in the discussion. However what I did I did mostly for fun, without paying much attention to the source code, documentation and endless issue lists on github. By no means I claim this tutorial will work for you but I do think I shared the key points and effort estimations to help others decide if they want a full-node LN client too. I'm also interested in some ideas on what to do with it next (rather unlikely that I will share my lnd admin.macaroon with anyone!) especially if it gives me free money. For example, I can open 1000 channels and start earning money from fees, although I no longer have more Bitcoins than the LN capacity yields... I will probably keep updating the software on my Pi until it leaves beta phases and only then will pour more money inside. I'm also keen on improving the general security of my rig and those comments I will answer more seriously.
