以太坊

Ether's.

以太坊（Ethereum）是一个开源的有智能合约功能的公共区块链平台，通过其专用加密货币以太币（Ether）提供去中心化的以太虚拟机（Ethereum Virtual Machine）来处理点对点合约。

Etheeum is an open-source public block chain platform with smart contracts that are processed through a decentralised Etherium Virtual Machine, which is provided with a dedicated encrypted currency in Ether.

以太坊虚拟机（EVM）

Etheria Virtual Machine (EVM)

以太坊虚拟机（EVM）是以太坊中智能合约的运行环境。它不仅被沙箱封装起来，事实上它被完全隔离，也就是说运行在EVM内部的代码不能接触到网络、文件系统或者其它进程。甚至智能合约之间也只有有限的调用。

The Etheraya Virtual Machine (EVM) is the operating environment of the Taiyo Smart Contract. Not only is it packed in sandboxes, but it is in fact completely isolated, that is, the code running inside the EVM cannot reach the network, file system, or other processes.

账户（Accounts)

Accounts (Accounts)

以太坊中有两类账户，它们共用同一个地址空间。外部账户，该类账户被公钥-私钥对控制。合约账户，该类账户被存储在账户中的代码控制。外部账户的地址是由公钥决定的，合约账户的地址是在创建合约时确定的（这个地址由合约创建者的地址和该地址发出过的交易数量计算得到，地址发出过的交易数量也被称作“nonce”）

There are two types of accounts in the courthouse, which share the same address space. External accounts, which are controlled by the public-private key pair. Contract accounts, which are stored in the account, are controlled by the code. The address of the external account is determined by the public key. The address of the contract account is determined at the time of the creation of the contract (this address is calculated by the address of the creator of the contract and the number of transactions sent by that address, and the number of transactions sent is also referred to as “nonce”).

交易（Transactions）

Tradings

一笔交易是一条消息，从一个账户发送到另一个账户。交易可以包含二进制数据（payload）和以太币。

A transaction is a message sent from one account to another. A transaction can contain binary data (payload) and an Ether currency.

Gas

以太坊上的每笔交易都会被收取一定数量的gas，gas的目的是限制执行交易所需的工作量，同时为执行支付费用。当EVM执行交易时，gas将按照特定规则被逐渐消耗。

When EVM executes the transaction, it will be consumed in accordance with specific rules.

超级链（Xuper Chain）

Super Chain (Xuper Chain)

百度超级链是百度自研的具备强大的网络吞吐能力、高并发的有效性验证能力和可扩展的存储能力的区块链3.0解决方案。

The 100-degree superchain is the 100-degree self-researched solution of 3.0 per cent of the block chain with a strong network absconding capacity, high-commitability validation capacity and scalable storage capacity.

超级节点/监督节点

Supernode/supervised node

超级节点是超级链中的特殊节点，采用分布式计算技术，保证每个节点的存储和计算是可以扩展的，从而为区块链网络提供源源不断的存储和计算支持。在非 POW 的共识机制下，超级节点会计算链上提交的交易，并执行合约。超级节点采用多核并行计算与分布式计算相结合的方式提升计算效率。而监督节点主要用于交易的验证。

Supernodes are special nodes in the super-chain, using distributed computing techniques to ensure that each node is stored and calculated in an expansionable manner, thus providing a continuous stream of storage and computational support for the block chain network. Under the non-POW consensus mechanism, supernodes calculate transactions submitted on the chain and execute contracts. Supernodes improve computing efficiency by combining multiple-nucle parallel calculations with distributed calculations. Supernodes are mainly used to verify transactions.

智能合约

Smart Contract

由于 UTXO (Unspent Transaction Output) 模型相较于 Account 余额模型有更好的并发性，超级链底层基于 UTXO 模型，扩展了对智能合约的支持，并且可以加载不同的合约虚拟机。

Because the UTXO (Unspent Transport Output) model is better and more dynamic than the Account balance model, the superchain bottom is based on the UTXO model, extending support for smart contracts and allowing for the loading of different contractual virtual machines.

立体网络

StereoNet

超级链采用链内并行技术、可回归侧链技术、平行链技术在区块链上实现了立体网络。

Super-chains use parallel technologies within chains, recalibrable side-chain technologies, and parallel-chain technologies achieve stereo networks on block chains.

链内并行：超级链将事务挖掘形成 DAG 图，并由 DAG 图来控制事务的并发执行。 可回归侧链：超级链通过把复杂的智能合约放在侧链执行，实现利用其它并行资源而不消耗主链资源，当满足侧链回归条件时，主动引发侧链合并。 平行链：超级链可以通过 Root 链来创建一个独立的、真实的区块链体系。

The chain is parallel: the super-chains dig the matter into a DAG figure, and the DAG maps control it. The side-chains can be returned: the super-chains are implemented by placing complex smart contracts in the side chain, using other parallel resources without consuming the main-chain resources, and when the side-chain returns conditions are met, the side-chain merges are initiated.

轻量级节点

Lightweight Node

轻节点仅同步少量数据就可以完成数据的访问和校验，适用于普通 PC、手机和嵌入式设备上，不需要强大的算理和存储就能有效访问区块链网络数据。

A light node can complete access to and validation of data only by synchronizing a small amount of data, applying to ordinary PCs, mobile phones and embedded devices, without the need for strong algorithms and storage to effectively access block chain network data.

# Supernode accounts: nodes with billing rights and block rights, account information is generated randomly
