区块链技术比较

EOS(Graphene)

解决了哪些问题:

  1. 应用性能低 (石墨烯技术)
  2. 安全性差 (DPOS 共识算法)
  3. 开发难度高
  4. 手续费高

EOS(Graphene) vs Ethereum

Ethereum Design

Design philosophy

Ethereum has no common functions. It’s a common platform
EOS has build-in common functions like crypto, database save development time and effort

Consensus & Governance

Graphene

Graphene has been designed especially for transactions (token transfer) and high-throughput in order to compete with Visa and Mastercard.

However, the more we’ve drilled down the Graphene core source code, the more we’ve understood why Dan Larimer left the project and completely switched to EOS. Here are some main issues we’ve found:

Substrate & Polkadot

Governance
Scalability
Future-proofing
Developability
Interoperability
efficiency

Polkadot的主要目的是将现在各自独立的区块链连接起来,通过Polkadot,不同区块链之间可以进行通信和数据的传递,智能合约的调用。

解决扩展性:平行链宇宙
解决跨链:转接桥+中继链

Polkadot是如何解决扩展性的?

① 一个主链可以挂各种平行链,平行链通过转接桥可以接进来。不要求是以太系。btc,EOS通过桥也可以接进来。
②平行链的安全性可以集中到主链中,形成一个安全池。
③各个平行链之间可以通过中继链互相连通,包括智能合约的调用。

因此,Polkadot可以让dapp跑自己的平行链,并且具有主链的安全性,这可以解决 one platform for all 的问题,但是如果这个dapp本身对吞吐量要求就特别高的话,那还是得平行链自己来解决,比如EOS。
