Project Overview
Lightning Network(LTG) is a Bitcoin Layer2 ecosystem that incentivizes users to participate in the Bitcoin mainnet asset protocol ecosystem through a DeFi-like liquidity mining or staking reward mechanism, such as running Lightning Network nodes, providing channel liquidity, or forwarding asset transactions.
Paystand Launches USDb, a Stablecoin Built on the Bitcoin Ecosystem
According to Businesswire, Paystand, a blockchain-based B2B payment network, has announced the launch of USDb, a stablecoin built on the Bitcoin ecosystem. USDb is backed 1:1 by U.S. dollar reserves and is natively deployed on the Bitcoin sidechain Rootstock, while also being compatible with the Liquid Network and the Bitcoin Lightning Network. Notably, USDb is primarily designed for traditional corporate finance use cases, including accounts receivable/payable, cross-border payroll, and treasury management.
Bitcoin Core Releases v31.0 Version with Improvements to Mempool Logic
Odaily News Bitcoin Core has released version v31.0. This update primarily improves the Mempool logic. Nodes can now more accurately assess the overall value of a set of related transactions to decide whether to retain, forward, or include them in a block. The impact on regular transfer users is minimal, but users employing RBF, CPFP, the Lightning Network, complex wallets, or server-side wallets may encounter changes in transaction acceptance/rejection behavior. The private transaction broadcast feature has been enhanced, supporting broadcasting sendrawtransaction via Tor/I2P, preventing recipients from obtaining the transaction initiator's IP address and geographical location.
Solv Protocol Integrates Utexo to Launch Native Bitcoin Yield Solutions Based on RGB and the Lightning Network
According to GlobeNewswire, Solv Protocol announced a strategic integration with Utexo to launch a native Bitcoin yield solution built on the RGB protocol and the Lightning Network. This solution enables atomic swaps between native BTC and USDT—without wrapping, cross-chain bridges, or custodians. It emphasizes self-custody, privacy protection, and final settlement, aligning with Tether’s prior announcement of natively issuing USDT on an RGB-compatible Lightning Network. Additionally, Solv participated as a strategic angel investor in Utexo’s $7.5 million seed funding round, led by Tether.
StarkWare Researcher Proposes Bitcoin Post-Quantum Transaction Scheme Without Soft Fork
According to The Block, Avihu Levy, a researcher at StarkWare, published a paper proposing the Quantum Safe Bitcoin (QSB) scheme, claiming it enables quantum-resistant transactions under Bitcoin’s existing script rules—without requiring a soft fork. This scheme replaces elliptic-curve cryptography with the RIPEMD-160 hash function via a “hash-to-signature” puzzle, thereby enhancing resilience against quantum attacks. The paper notes that QSB’s current per-transaction cost ranges from $75 to $150—significantly higher than today’s average transaction fee—and involves complex user experience; thus, it is recommended only as a “last resort.” The scheme remains constrained by script opcodes and size limits, and does not yet support all use cases—such as the Lightning Network. Compared to BIP-360—which requires protocol-level changes—QSB needs no modifications to the Bitcoin protocol, but remains experimental.
