More on Making a Dwelling Off of Bitcoin

For this reason, Bitcoin Core limits1 the maximum number and size of related transactions. The higher the Bitcoin value rises, the smaller the decimal transaction size will become. Digital gold: Another potential outcome for bitcoin is its use as a form of digital gold or a digital store of value. Rusty Russell is organizing meetings to help speed up the specification process and has started a thread asking for feedback about what medium to use for the meeting (Google Hangout, IRC meeting, something else) and how formal to make the meeting. If at all possible, it is preferable to build software and services in a way that doesn’t require the types of fast and arbitrary searches that block explorers make convenient. These messages were implemented to make it easier for developers of lightweight clients to get feedback on connection and transaction relay problems. If they average $1 million each, it means $250 million in transaction value is performed per minute. If such an attack was performed across the whole network, it might be able to prevent certain transactions from reaching miners, possibly breaking the security of protocols that rely on timely confirmation (e.g. LN payment channels). 2439 adds the default policy for the watchtower, such as allowing the tower to handle a maximum of 1,024 updates from a client in a single session, allowing the watchtower to receive a reward of 1% of the channel capacity if the tower ends up defending the channel, and setting the default onchain feerate for justice transactions (breach remedy transactions).

It takes an average of 10 minutes for the mining network to validate a block and create the reward. It is misleading to think that there is an analogy between gold mining and bitcoin mining. And even if it one day becomes possible to run all bitcoin mining on renewable energy, its e-waste problem remains. This can be a major problem for protocols like LN that rely on timelocks-if a transaction isn’t confirmed before the timelock expires, the counterparty can take back some or all of the funds they previously paid. This mitigates a perceived problem with some advanced scripts where it might be possible for a counterparty or third party to add extra data to a transaction, lowering its feerate and likely making it take longer to confirm. If you want to get into trading, put aside some extra money when you have it, find a coin you'd be into trading, and buy some to play with. ● Close open RPC ports on nodes: about 13% of Bitcoin nodes appear to have their RPC ports open on unencrypted public connections, putting users of those nodes at risk. ● Review proposed BIP322 for generic message signing: this recently-proposed BIP will allow users to create signed messages for all currently-used types of Bitcoin addresses, including P2PKH, P2SH, P2SH-wrapped segwit, P2WPKH, and P2WSH.

Currently, discussion appears to be most active on the BIP proposal’s pull request. Osuntokun’s pull request for LND is still marked as a work in progress as of this writing, so we don’t know yet when the feature will become generally available to LND users or whether other LN implementations will also provide the same feature in a compatible way. ● PR opened for spontaneous LN payments: LN protocol developer Olaoluwa Osuntokun opened a pull request to allow an LN node to send a payment to another node without first receiving an invoice. Or you just publish your node’s information and users can send you donations without having to get an invoice first. Even if they don’t see general adoption, their privacy advantage means they could end up well deployed among niche users.

Since May 2020, we’ve been in the fourth cycle, and we’ll see what happens over the next year. It has the potential to become an industry standard that will be implemented by nearly all wallets and may be used by many services (such as peer-to-peer marketplaces) as well as for customer support, so Optech encourages allocating some engineering time to ensure the proposal is compatible with your organization’s needs.

736 adds support for both connecting to Tor hidden services (.onion) and operating as a hidden service. 2127 adds a new --plugin-dir configuration option that will load plugins in the indicated directory. 2007 adds a new MaxBackoff configuration option that allows changing the longest amount of time the node will wait before giving up attempting to reconnect one of its persistent peers. 15226 adds a blank parameter to the createwallet RPC that allows creating a wallet without an HD seed or any private keys. 8, Bustapay provides improved privacy for both spenders and receivers-and also allows receivers to accept payments without increasing the number of their spendable outputs, a form of automatic UTXO consolidation. The number of bitcoins in circulation is limited by and managed by the original computer code and traded through one of several digital, decentralized exchanges. RPC communication is not encrypted, so any eavesdropper observing even a single request to your server can steal your authentication credentials and use them to run commands that empty your wallet (if you have one), trick your node into using a fork of the block chain with almost no proof-of-work security, overwrite arbitrary files on your filesystem, or do other damage.
