IN 2023, THE BOTS PAY YOU! ⚡️🤖
today we're releasing a new L402 specification, along side @LangChainAI powered tools that enable AI Agents to traverse L402 APIs (HTTP 402 pay-per call APIs over Lightning), and also directly hold+manage Bitcoin via @OpenAI function calls
in response to the rise of data hungry LLM models, and the ease of web scraping enabled by structured use of the models, we're seeing the Web revert to a closed structure where sites closely guard resources in an attempt to stave off bots and also monetize their AI training fuel

glanced at Ark, seems like a mash up of TumbleBit+Statechains w/ CTV to make things less interactive
like TumbleBit, it has a set coordinator, and epoch rounds where notes are exchanged for UTXOs or other notes
like Statechains, sender can collude w/ operator to double spend
advertises that inbound liquidity constraints don't apply, but the coordinator needs enough capital to fully back all the UTXOs exchanged in each round
worst case everything needs to unroll, so amts sent still need to be economical relative to chain fees

excited to announce tapd (Taproot Assets P{rotocol Daemon) v0.2-alpha! 🥕
w/ this release, tapd can now be used w/ lnd v0.16.x, and also now comes bundled with litd v0.10
🎶TAP, TAP, TAP IN! 🎶
this release contains some flag ship features, let's break em down right quick 👇
Universe servers are an on-chain index into the Bitcoin blockchain that allows applications to: verify the existence of assets, and also query the Taproot Assets overlay layer
if you're running an lnd routing node, here're some tips to keep your node afloat during the current mempool storm ⛓️🌊⚡️:
1. You can use the BumpFee (`lncli wallet bumpfee`) command to use CPFP to increase fee rate of a txn (close, open, sweep, etc): lightning.engineering/api-docs/api/l…
the first fee bump will use CPFP (you can watch the current sweeps using `lncli wallet listsweeps), subsequent calls will use RBF to increase the fee rate of the package
it doesn't do effective ancestor fee rate calculation rn tho, we have a SoB intern working on that 😎
Taro uses the Taproot script tree to commit to extra structure metadata which enables the representation and transfer of assets on Bitcoin
Taro uses a new data structure I call a Merkle Sum Sparse Merkle tree which combines the properties of a merkle sum tree along with a Sparse Merkle Tree to construct commits that enable 3rd party supply/balance verification and also efficient proofs of non-inclusion
