韭菜百科 - 以太坊 | 以太坊(ETH)是当前市值仅次于比特币排名第二的区块链货币,也是首个具有相对完备智能合约的货币。以太坊的区块中可以储存合约代码,用户可以通过向合约地址发起请求调用执行合约代码。智能合约促生了一类名为分布式应用(DApp)的新型产品,支撑着在区块链技术上构建的智能经济与其他生态发展。IDCard社交网络本身也是一个DApp。
Newbie On Chain: A transaction is a message that is sent from one account to another account. It can include binary data and Ether. If the target account contains code, that code is executed and the payload is provided as input data. If not, the transaction creates a new contract. The output of this execution is permanently stored as the code of the contract. This means that in order to create a contract, you do not send the actual code of the contract, but in fact code that returns that code when executed.
Quick Fact of EVM: The Ethereum Virtual Machine is the runtime environment for smart contracts in Ethereum. It is not only sandboxed but actually completely isolated, which means that code running inside the EVM has no access to network, filesystem or other processes. Smart contracts even have limited access to other smart contracts. There are two kinds of accounts in Ethereum: External accounts and contract accounts, and the two types are treated equally by the EVM.
山寨币真的山寨吗?答案是否定的。人们习惯于把除比特币以外的区块链货币称为山寨币。优秀的“山寨币”们并不是真的山寨,而是借鉴比特币白皮书中的设计,基于区块链技术开发的具有更先进功能或解决实际痛点的2.0货币。例如加强了区块链匿名转帐能力的匿名币,在CDN需求上崭露头角的硬盘币等。可以说,这些2.0货币正是当今区块链生态的构建者。
The South Korean government reportedly plans to soften its crypto regulations in line with the policies set by the G20 nations in an effort to create “unified regulations.” The Korean regulators have also agreed to apply the standards set by the Financial Action Task Force to its crypto policies.
2018/5/18, The United Nations Development Program (UNDP) is launching a crypto-funded initiative to power a university in Moldova with solar energy. The project in partner with a energy exchenge market, will allow people to buy solar cells and then lease them to the Technical University in Chisinau. The purchases will be made using Solarcoin, a crypto launched by the blockchain startup Electricchain. SOLARCOIN# blockchain#
Newbie On Chain: A blockchain is a globally shared, transactional database. Any change in the database are accepted by all others simultaneously. On blockchain, everyone has a synchronized account book, which makes a centralized ‘bank’ no longer necessary. The transactions will be encrypted by hashing, bundled into a “block”, and distributed among all others. These immutable blocks form a linear sequence--the so-called “blockchain” and exist permanently.
韭菜百科 - ICO(Initial Coin Offerin) | 首次代币发行,是由IPO(首次公开募股)衍生而来的币圈原创词。通常是一个区块链货币团队在项目正式落地前通过分发代币获得投资和支持的融资方式。
虚拟货币?数字货币 or 区块链货币?很多韭菜(比如我也)在提到比特币时会用虚拟货币或数字货币指代。两者其实都不太准确。虚拟货币范围较广泛包括各种虚拟游戏币甚至Q币,而数字货币不局限于线上产品,可应用于真实的商品和服务交易。早期数字货币以黄金抵押创建为主。而BTC和Ripple等便是应用区块链技术的新型数字货币了。
Newbie On Chain: Ethereum is referred as a series of contracts defining decentralized apps. Smart contracts are used in ETH: they are collections of code (functions) and data (state) that resides at a specific address on the Ethereum blockchain. By building contracts on EVM, users can create cryptocurrency, process transaction, build new ‘ecosystem’, etc. Moreover, all traces will be permanently embedded on chain, which costs certain amount of price (GAS) in return to maintain the whole ETH system.

韭菜百科 - 比特币 | 比特币是一种开源的去中心化(基于P2P技术的)货币,被认为是区块链货币的鼻祖。自2009年1月3日由中本聪发布以来比特币知名度不断提高,很多线上商城或个人商家已逐渐开始接受比特币作为支付手段。比特币由矿工组织驱动发行和转帐,发行量为2100万颗,对标世界黄金总储量的2100万吨,所以也常被认为是虚拟货币的黄金。
