感謝你的付出，近一年開始看你的YouTube片，著作和博客舊文，獲益良多，此外亦有坊間其他YouTube Channels,有感Channels內大多和幣價上落/應用操作（如Defi/NFT) 有關，比較少關於實際上如何寫code，甚至創立區塊鏈項目的資訊，所以想問一下如果門外漢想更深入參與區塊鏈行業，應如何開始，哪裏有相關內容
Cosmos 是好的鏈，我們volitium 也考慮在Cosmos 寫我們的Dapp, 主要是我們能夠自己控制transaction fees, 這對我們的應用很重要。
看來很多developer都因gas fee太貴而離開Ethereum, Ethereum 的前景不太好嗎？
我並不擔心呢，現時以太坊上有超過3000個Dapp, 在以太坊上的total value lock 在Defi 收息的總額達1000億美元，看下圖：
微軟創辦人Bill Gates預計2023年以太坊將成為去中心化app store, 就如蘋果的app store一樣
其實，developer 可以在不同鏈同時建立Dapp, 只是暫時選擇其中一個平台launch 咗先而巳！
Ethereum white paper predicted DeFi but missed NFTs: Vitalik Buterin
Buterin still believes that “the internet of money should not cost more than 5 cents per transaction” and highlighted Ethereum’s continued efforts to improve the blockchain’s scalability capabilities.
Rounding up the last decade, Ethereum co-founder Vitalik Buterin revisited his predictions made over the years, showcasing a knack for being right about abstract ideas than on-production software development issues.
Buterin started the Twitter thread by addressing his article dated Jul. 23, 2013 in which he highlighted Bitcoin's (BTC) key benefits — internationality and censorship resistance. Buterin foresaw Bitcoin’s potential in protecting the citizens’ buying power in Iran, Argentina, China and Africa.
However, Buterin also noticed a rise in stablecoin adoption as he saw Argentinian businesses operating in Tether (USDT). He backed up his decade-old ideas around the negative impacts of Bitcoin regulation.
The entrepreneur still believes that “the internet of money should not cost more than 5 cents per transaction” and highlighted the [development of Ethereum’](https://www.blockchainx.tech/erc20-token-development)s continued efforts to improve the blockchain’s scalability capabilities.
“I liked altcoins before altcoins were cool,” added Buterin citing an article where he based this claim via three arguments: different chains optimize for different goals, costs of having many chains are low and need of an alternative in case the core development team is wrong.
On the flipside, Buterin backtracked on his support for Bitcoin Cash (BCH), stating that communities formed around a rebellion, even if they have a good cause, often have a hard time long term, adding that “they value bravery over competence and are united around resistance rather than a coherent way forward.”
“A lot correct (basically predicted "DeFi"), though incentivized file storage + compute hasn't taken off that much (yet?), and of course I completely missed NFTs.”
Concluding the findings, Buterin supported the instincts that helped him correct mistakes early on, stating: “On tech, I was more often right on abstract ideas than on production software dev issues. Had to learn to understand the latter over time.”
In early December, Buterin shared his vision for a “plausible roadmap” for ETH 2.0, suggesting “a second tier of staking, with low resource requirements” for distributed block validation.
Additionally, he proposed the introduction of fraud-proof or ZK-SNARKS that can serve as a cheaper alternative for users to check block validity. According to Buterin:
“\[With these updates\] We get a chain where block production is still centralized, but block validation is trustless and highly decentralized, and specialized anti-censorship magic prevents the block producers from censoring.”
