懷念旅遊的日子，四年前去過瑞士旅遊時，亦專程揸車進入有加密貨幣谷（Crypto Valkey)之稱的City of Zug朝聖，那兒是以太坊的總部的所在地，根據地址尋找，最後發現原來只是一間看似住宅的樓上細小律師事務所，看來只是掛單註冊地址，看完之後有所頓悟：市值三千幾億美元的以太坊，是去中心化的平台，Dapp是由世界各地的人創建，儲存區塊鏈的節點是由世界各地的人經營，為何需要寫字樓？這跟有些香港銀行必須要有寫字樓的租約文件才可以考慮（只是考慮）開商業戶口，這種想法已經跟時代格格不入！
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.

“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.”
