このAIとのディスカッションはめちゃくちゃ面白い。仮想通貨におきかえて考えてみたい。

Vitalik：创新应转向 Layer2，4年内完成向抗量子加密的过渡 Vitalik Buterin 在 Devconnect 大会上表示，希望以太坊逐步“固化”（ossify）其底层协议，减少核心更改，优先保障稳定性和安全性。他强调，创新应转向 Layer2、钱包、隐私工具等外围生态，而非频繁修改主链。尽管承认这种转变会削弱早期探索精神，但他认为这对整个生态更“健康”。 此外，他警告称椭圆曲线加密可能在2028年前被量子计算攻破，以太坊必须在四年内完成向抗量子加密的过渡。

メモ。AIと仮想通貨が、可処分電力で競合関係にある。 ブロックチェーンの提供する社会機能の9割ぐらいは、ブロックチェーン無しにも成立するので、電力足らなくなると、どうなるんか。

Well boys, think I figured out (part of) the scam, and it is a doozy. Strap in. TLDR: Stream (xUSD) and Elixir (deUSD), and likely more, are recursively minting each other tokens in order to inflate there own TVL and create a ponzu the likes of which we haven't seen for awhile in crypto. NOTE: In the name of readability and due to X restrictions all txn hashes and addresses will be posted in a follow up tweet for those that wish to follow along themselves. We start our journey on mainnet, watching the flow of USDC funds that have just landed in the Stream xUSD wallet last night. 0x15 - First step is to transfer the USDC out to another Stream controlled address 0x33, in this case to the tune of $4.4m. - 0x33 places a cow swap order to buy USDT, which is paid out to 0x25. - 0x25 takes that USDT and uses it to mint the equivalent amount of deUSD from their on chain minter 0x69 - 0x25 then transfers the deUSD back to 0x33 which in turn transfers it back to the main Stream wallet 0x15. - Stream then takes that deUSD and bridges to AVAX, World chain or any other L2 that has lending markets listing sdeUSD, uses it as collateral to borrow other stables such as USDT or AUSD, swaps to USDC and bridge back to mainnet. This is repeated one or two more times with varying amounts and lending markets, but the end state is Stream mints deUSD, uses that as collateral to borrow stables and mints more. Yesterday they did 3 rounds to mint about 10m deUSD. While degenerate yes, not inherently scammy. Enter Part 2 Usually when leverage looping, the last txn is just to supply the last amount as collateral. But Stream has a special power, which is their wallet receive's all USDC used to mint their "stable" coin xUSD and boy do they use it. So with the final USDC they borrowed they recursively mint their own xUSD coin. Yesterday using the same $1.9m USDC they minted about 14.5m xUSD as shown in the tweet below. This means xUSD is not only not actually backed 1:1 but the protocol itself is the largest holder of the token. It currently controls over 60% of the xUSD in circulation, meaning if we assume all is recursively minted like this then each xUSD is backed by at most $0.40. But for what purpose? Well this is where it gets fun. The main thing to do with xUSD other than hold, is leverage loop it where listed on Euler, Morpho etc. But who would lend millions of stables against a token the protocol just minted out of thin air you ask? 🤔 Well none other than our friends at Elixir who happen to find themselves with an extra $10m newly acquired USDT. 🤯 - Step one is to transfer the $10m USDT to what their "Transparency Dashboard" labels "Elixir's sUSDS Multisig" (lol) 0x73 - Next 0x73 creates a Cow swap order to swap the USDT back to USDC and have it land in 0x1b - 0x1b bridges the $10m USDC to Plume network and then transfers it to a Safe at 0xaF8 - The Elixir Safe then supplies the USDC directly to a Morpho market that lends against, you guessed it xUSD. -This market is hidden from all available morpho UI's and Elixir is the only depositor. There is currently over $70m USDC supplied and >$65m borrowed. - Shortly after each deposit Stream will then come along with its brand new xUSD it minted to itself, borrow the USDC, bridge back to mainnet and we find ourselves back at the start of the story. Funny enough as I was writing this they seem to be kicking off another round starting with another minting of deUSD. While I did not dive fully in yet I would assume most markets that Stream uses to borrow against deUSD are also funded in similar manners, potentially by other partner "stable coins" engaging in the same tactics. It is hard to know for sure how much actual collateral is backing this full system but seems likely to be sub $0.10 per $1. Though what's a bit of leverage when you can each advertise 10-15% TVL growth overnight, just look at this beautiful chart from the Elixir dashboard showing their TVL growing about $60m in just a few weeks. (that amount sounds familiar) The exposure runs rampant through DeFi, not only just holding xUSD or deUSD but depositing into any market or curated vault that lends against them or the other Yield coins that also are at least in part backed by these. Make sure you know where your yield is coming from. Happy Farming.
