London Blockchain Conference, BSV’s next era

This week’s episode of the CoinGeek Weekly Livestream was an Ask Me Anything (AMA) with Kurt Wuckert Jr. It covered OP_CAT and Core V30 on BTC, BSV on-chain activity after Teranode, and the upcoming London Blockchain Conference.

The latest tech development on BTC

Two viewer questions ask about tech upgrades on BTC. The first is about OP_CAT going live, and the second is about BTC v30.

Answering the first one, Wuckert says this enables some smart contract functionality on BTC, but its fundamental limitations won’t allow this to amount to much. Costs and limits to script and block sizes are baked in at this point, so this isn’t a threat to BSV.

As for Core v30, it’s cool, but again, it doesn’t change the limits of this blockchain. This enables basic functionality, but there are still hardcore small blockers who oppose anything like this. It’s a baby step in the right direction, but it’s nowhere near where BSV is after seven years of development.

CoinGeek and the wider BSV ecosystem

One viewer asks how Wuckert’s various media appearances have been arranged. He says CoinGeek arranged some of the Fox News appearances, but many of the others, such as the Patrick Bet-David and Hotep Jesus podcast appearances, were coordinated by the BSV community.

Another viewer asks about the upcoming London Blockchain Conference and whether Wuckert has any teasers about announcements. He doesn’t, explaining that it’s a fully separate organization. CoinGeek is going as a media partner, but doesn’t have much insight into what will be announced. In fact, CoinGeek doesn’t even have access to speakers until the conference itself. Wuckert is excited to attend and looking forward to seeing old friends and meeting new people interested in the sector.

The Teranode era and what it means for BSV

Does Wuckert expect lots of on-chain activity from businesses waiting on the sidelines for Teranode to go live?

He doesn’t know the details yet, but he does know many app developers, stablecoin companies, and others who have been briefed over the years. When Teranode goes live, they’ll have every opportunity to move across to BSV. He says these things tend to happen slowly, then suddenly, and he expects that to happen.

As for which applications are right for the moment we’re in, Wuckert points to stablecoins. Some of the tokenization stuff is still pretty far out, but the regulations and development are just right for stables. Businesses understand the benefits of using them, but they haven’t yet figured out the costs and limitations of using them on Ethereum, and when they do, BSV will be ready.

As for what might come next, it’s anyone’s guess. The tooling and SDKs on BSV are much better than before, and Bitcoin Script, while complex, enables anyone to create virtually anything. When Teranode takes over fully, there won’t be any limits to what can be built on public, scalable blockchains.

GorillaPool and Wuckert’s grand vision

A viewer asks how GorillaPool stays afloat, given how unprofitable mining is. Wuckert explains that, while they’re right that mining itself is unprofitable, relationships with energy providers and other means to profit, including software development, mean the company is sustainable. He praises GorillaPool’s developers as some of the most competent and visionary he has ever encountered.

As for the grand vision for the company, Wuckert sees it as an ISP like Verizon or Xfinity. It’s an infrastructure layer that enables connectivity on the Internet of Value (Metanet). People will be able to exchange value peer-to-peer because GorillaPool mines blocks on BSV, he says

Preliminary analysis of the Balancer V2 attack, which resulted in a loss of $120 million.

On November 3, the Balancer V2 protocol and its fork projects were attacked on multiple chains, resulting in a serious loss of more than $120 million. BlockSec issued an early warning at the first opportunity [1] and gave a preliminary analysis conclusion [2]. This was a highly complex attack. Our preliminary analysis showed that the root cause was that the attacker manipulated the invariant, thereby distorting the calculation of the price of BPT (Balancer Pool Token) -- that is, the LP token of Balancer Pool -- so that it could profit in a stable pool through a batchSwap operation. Background Information 1. Scaling and Rounding To standardize the decimal places of different tokens, the Balancer contract will: upscale: Upscales the balance and amount to a uniform internal precision before performing the calculation; downscale: Reduces the result to its original precision and performs directional rounding (e.g., inputs are usually rounded up to ensure the pool is not under-filled; output paths are often truncated downwards). Conclusion: Within the same transaction, the asymmetrical rounding direction used in different stages can lead to a systematic slight deviation when executed repeatedly in very small steps. 2. Prices of D and BPT The Balancer V2 protocol’s Composable Stable Pool[3] and the fork protocol were affected by this attack. Stable Pool is used for assets that are expected to maintain a close 1:1 exchange ratio (or be exchanged at a known exchange rate), allowing large exchanges without causing significant price shocks, thereby greatly improving the efficiency of capital utilization between similar or related assets. The pool uses the Stable Math (a Curve-based StableSwap model), where the invariant D represents the pool's "virtual total value". The approximate price of BPT (Pool's LP Token) is: The formula above shows that if D is made smaller on paper (even if no funds are actually withdrawn), the price of BPT will be cheaper. BTP represents the pool share and is used to calculate how many pool reserves can be obtained when withdrawing liquidity. Therefore, if an attacker can obtain more BPT, they can profit when withdrawing liquidity. Attack Analysis Taking an attack transaction on Arbitrum as an example, the batchSwap operation can be divided into three stages: Phase 1: The attacker redeems BPT for the underlying asset to precisely adjust the balance of one of the tokens (cbETH) to a critical point (amount = 9) for rounding. This step sets the stage for the precision loss in the next phase. Phase Two: The attacker uses a carefully crafted quantity (= 8) to swap between another underlying asset (wstETH) and cbETH. Due to rounding down when scaling the token quantity, the calculated Δx is slightly smaller (from 8.918 to 8), causing Δy to be underestimated and the invariant D (derived from Curve's StableSwap model) to be smaller. Since BPT price = D / totalSupply, the BPT price is artificially suppressed. Phase 3: The attackers reverse-swap the underlying assets back to BPT, restoring the balance within the pool while profiting from the depressed price of BPT—acquiring more BPT tokens. Finally, the attacker used another profitable transaction to withdraw liquidity, thereby using the extra BPT to acquire other underlying assets (cbETH and wstETH) in the Pool and thus profit.
