Solana,可能正在迎来下一轮活跃期。但这一次的变化,可能不只是靠 Meme 带热度。 最近 Solana 生态出现了几个比较明显的信号:RWA、代币化股票、Meme 市场同时回暖,再加上治理机制升级,整个生态正在重新恢复活力。 先看 RWA 根据 数据,截至7月3日,Solana 链上 RWA 持有钱包数量已经超过29.3万个,占全网约31%,排名第一。 同时,Solana 链上的 RWA 资产数量达到2119个,也是所有公链中最高。 不过,单看资产规模,Solana 还没有追上 Ethereum。目前 Solana 链上 RWA 总价值约35.5亿美元,和以太坊相比仍有差距。 但资金流向已经释放出信号。过去30天,Solana 链上 RWA 净流入超过10亿美元,明显领先多个主流公链。这说明市场资金正在关注 Solana 的资产上链机会。 其中,最明显的推动力来自代币化股票。以前大家提 RWA,更多想到的是债券、房地产等传统资产。但现在,一个新的方向正在出现:把美股股票搬到链上。 目前,代币化资产已经占 Solana 现货周交易量约10%,而年初这个比例只有1%。Solana 上代币化股票周交易量更是突破14亿美元,占整个代币化股票市场约96%。 背后的重要推动者,就是近期进入市场的代币化股票平台。例如 Backpack 推出的代币化股票产品,其中 SPCX、MU 等资产贡献了 Solana 链上大量交易量。 这意味着,Solana 正在从单纯的 Meme 交易链,逐渐变成一个承载更多金融资产的交易网络。当然,Solana 最熟悉的 Meme 市场,也正在恢复热度。 近期 ANSEM Meme 币的爆发,再次点燃了链上交易情绪。虽然 Meme 的周期性很强,但它带来的资金活跃度是非常直接的。 等平台的数据也显示,近期新币发行和交易量明显回升。Axiom、Phantom、GMGN 等 Solana 生态工具的收入,也出现今年以来的新高。 市场重新开始交易,开发者重新开始发币,用户重新开始参与。 除了市场层面,Solana 自身也在推进治理升级。 7月2日,Solana 基金会上线了新的链上治理机制 SGP。 过去 Solana 的协议升级,主要依赖开发者提交 SIMD

Interactive linear algebra tutor where you solve matrix problems with real-time AI hints.
u/CarefulArmadillo3496 · Reddit
SparkGap - an agentic linear algebra experience Hey everyone, I'm building sparkgap.ai , an interactive tutor for linear algebra. You fill in the matrices/vectors, the LLM gives you hints until you get it correct. The hope is that it will get smarter over time from the context of which questions were missed/answered correctly. As you master concepts, the progress ring next to each concept will slowly fill in. Hopefully it should be very difficult to get to full mastery. Feedback and qu

Solve math problems and collaborate with peers using AI assistance.
lemma1729 · HN
Hi HN, This is ProofTree, and in TLDR: it is a platform where you can chat with an AI to do math, the way you already do, with context-awareness and knows how you personally do math, connected to the fora of other live human mathematicians. So, when you are talking to an AI about a proof at 3 am, and you need a human expert looking at it, or a discussion around it, like you do on StackExchange, this is it! You need an approved email account to use it, so please write here if you would live to try it out.

Connect any two topics by finding paths through real Wikidata relationships.
u/hyperschlauer · Reddit
I built a free knowledge-graph game where every move follows a real Wikidata relationship I’m building Webwoven for OpenAI Build Week, and the beta is now live: https://www.webwoven.org It’s inspired by Wikipedia hopping: you start with one topic and try to reach a target in as few moves as possible. Every move follows a real relationship from a reviewed Wikidata graph. The game therefore shows why two topics are connected instead of treating ordinary page links as paths. Webwoven curr
