Yes. You pick a peer and after some setup, create a bitcoin transaction to fund the lightning channel; it’ll then take another transaction to close it and release your funds. You and your peer always hold a bitcoin transaction to get your funds whenever you want: just broadcast to the blockchain like normal. In other words, you and your peer create a shared account, and then use Lightning to securely negotiate who gets how much from that shared account, without waiting for the bitcoin blockchain.
Yes, Lightning is open source. Anyone can review the code (in the same way as the bitcoin code)
Similar to the bitcoin network, no one will ever own or control the Lightning Network. The code is open source and free for anyone to download and review. Anyone can run a node and be part of the network.
No, your bitcoin will never leave the blockchain. Instead your bitcoin will be held in a multi-signature address as long as your channel stays open. When the channel is closed; the final transaction will be added to the blockchain. “Off-chain” is not a perfect term, but it is used due to the fact that the transfer of ownership is no longer reflected on the blockchain until the channel is closed.
Example: A and B have a channel. 1 BTC each. A sends B 0.5 BTC. B sends back 0.25 BTC. Balance should be A = 0.75, B = 1.25. If A gets disconnected, B can publish the first Tx where the balance was A = 0.5 and B = 1.5. If the node B does in fact attempt to cheat by publishing an old state (such as the A=0.5 and B=1.5 state), this cheat can then be detected on-chain and used to steal the cheaters funds, i.e., A can see the closing transaction, notice it's an old one and grab all funds in the channel (A=2, B=0). The time that A has in order to react to the cheating counterparty is given by the CheckLockTimeVerify (CLTV) in the cheating transaction, which is adjustable. So if A foresees that it'll be able to check in about once every 24 hours it'll require that the CLTV is at least that large, if it's once a week then that's fine too. You definitely do not need to be online and watching the chain 24/7, just make sure to check in once in a while before the CLTV expires. Alternatively you can outsource the watch duties, in order to keep the CLTV timeouts low. This can be achieved both with trusted third parties or untrusted ones (watchtowers). In the case of a unilateral close, e.g., you just go offline and never come back, the other endpoint will have to wait for that timeout to expire to get its funds back. So peers might not accept channels with extremely high CLTV timeouts. -- Source
Tiny payments are possible: since fees are proportional to the payment amount, you can pay a fraction of a cent; accounting is even done in thousandths of a satoshi. Payments are settled instantly: the money is sent in the time it takes to cross the network to your destination and back, typically a fraction of a second.
Yes, but not in theory. You could make a poorer lightning network without it, which has higher risks when establishing channels (you might have to wait a month if things go wrong!), has limited channel lifetime, longer minimum payment expiry times on each hop, is less efficient and has less robust outsourcing. The entire spec as written today assumes segregated witness, as it solves all these problems.
No, for now. For the first version of the protocol, if you wanted to send a normal bitcoin transaction using your channel, you have to close it, send the funds, then reopen the channel (3 transactions). In future versions, you and your peer would agree to spend out of your lightning channel funds just like a normal bitcoin payment, allowing you to use your lightning wallet like a normal bitcoin wallet.
Not really. Anyone can set up a node, and so it’s a race to the bottom on fees. In practice, we may see the network use a nominal fee and not change very much, which only provides an incremental incentive to route on a node you’re going to use yourself, and not enough to run one merely for fees. Having clients use criteria other than fees (e.g. randomness, diversity) in route selection will also help this.
Lightning is already being tested on the Mainnet Twitter Link but as for a specific date, Jameson Lopp says it best
Nope, because there is no custody ever involved. It's just like forwarding packets. -- Source
Furthermore, the Lightning Network scales not with the transaction throughput of the underlying blockchain, but with modern data processing and latency limits - payments can be made nearly as quickly as packets can be sent. -- Source
Each exchange will get to decide and need to implement the software into their system, but some ideas have been outlined here: Google Doc - Lightning Exchanges
Note that by virtue of the usual benefits of cost-less, instantaneous transactions, lightning will make arbitrage between exchanges much more efficient and thus lead to consistent pricing across exchange that adopt it. -- Source
According to Rusty's calculations we should be able to store 1 million nodes in about 100 MB, so that should work even for mobile phones. Beyond that we have some proposals ready to lighten the load on endpoints, but we'll cross that bridge when we get there. -- Source
No you'd remember the information from the last time you started the app and only sync the differences. This is not yet implemented, but it shouldn't be too hard to get a preliminary protocol working if that turns out to be a problem. -- Source
Lightning is based on participants in the network running lightning node software that enables them to interact with other nodes. This does not require being a full bitcoin node, but you will have to run "lnd", "eclair", or one of the other node softwares listed above.
All lightning wallets have node software integrated into them, because that is necessary to create payment channels and conduct payments on the network, but you can also intentionally run lnd or similar for public benefit - e.g. you can hold open payment channels or channels with higher volume, than you need for your own transactions. You would be compensated in modest fees by those who transact across your node with multi-hop payments. -- Source
Sure, you can help write up educational material. You can learn and read more about the tech at http://dev.lightning.community/resources. You can test the various desktop and mobile apps out there (Lightning Desktop, Zap, Eclair apps). -- Source
No -- Source
lit doesn't depend on having your own full node -- it automatically connects to full nodes on the network. -- Source
LND uses a light client mode, so it doesn't require a full node. The name of the light client it uses is called neutrino
Upon opening a channel, the two endpoints first agree on a reserve value, below which the channel balance may not drop. This is to make sure that both endpoints always have some skin in the game as rustyreddit puts it :-)
For a cheat to become worth it, the opponent has to be absolutely sure that you cannot retaliate against him during the timeout. So he has to make sure you never ever get network connectivity during that time. Having someone else also watching for channel closures and notifying you, or releasing a canned retaliation, makes this even harder for the attacker. This is because if he misjudged you being truly offline you can retaliate by grabbing all of its funds. Spotty connections, DDoS, and similar will not provide the attacker the necessary guarantees to make cheating worthwhile. Any form of uncertainty about your online status acts as a deterrent to the other endpoint. -- Source
You typically want to have more than one channel open at any given time for redundancy's sake. And we imagine open and close will probably be automated for the most part. In fact we already have a feature in LND called autopilot that can automatically open channels for a user.
Frequency will depend whether the funds are needed on-chain or more useful on LN. -- Source
You don't really set up a "node" in the sense that anyone with more than one channel can automatically be a node and route payments. Fees on LN can be set by the node, and can change dynamically on the network. -- Source
Yes but it has to be implemented in the Lightning software being used. -- Source
You won't have to do anything. With autopilot enabled, it'll automatically open and close channels based on the availability of the network. -- Source

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:submitted by pabou to Bitcoin [link] [comments]
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 mostWhooaa, 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://127.0.0.1:28333Here 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!).
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.
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...
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.
