实施可信赖的生产者Light验证
In the EOSIO V1.2.0 release, we introduced Replay and Resync (#5130) to address the issue that as the blockchain grows, the time needed to set up a new node and replay the chain will also continue to rise. Building on that, in V1.3.0, we have included more performance enhancements called Trusted Producer Light Validation (#5631).
在EOSIO V1.2.0版本中，我们引入了重放和重新同步（＃5130）来解决随着区块链的增长，设置新节点和重放链所需的时间也将继续增加的问题。在此基础上，在V1.3.0中，我们提供了更多性能增强功能，称为Trusted Producer Light Validation（＃5631）。
In conversations with the community, we have been discussing the concept of a “trusted producer.” This would allow for blocks from specific Producer(s) to be considered “trusted” and only need light-verification. For example, Producers would have the ability to trust their own blocks and designate them as “light” drastically reducing propagation delays across their own internal networks of API and P2P nodes for blocks they produce in order to increase the overall performance of the network.
在与社区的对话中，我们一直在讨论“可信赖的生产者”的概念。这将允许来自特定生产者的块被视为“可信任”并且仅需要Light验证。例如，生产者将能够信任他们自己的块并将它们指定为“Light”，从而大大减少其自身内部网络API和P2P节点的传播延迟，以便为其生成的块提高网络的整体性能。
Overall, we expect to see a significant performance increase from this for Producers as they continue to optimize their own infrastructure to run the EOSIO blockchain. Note that light validation is intended to be used on the interior of a single block producer’s network of nodes, it is not intended to be used on P2P nodes connecting to other block producers since blocks traversing the P2P net between producers must continue to be fully validated in order to maintain integrity of the blockchain.
总体而言，我们预计生产者将继续优化自己的基础设施以运行EOSIO区块链，从而显着提高性能。请注意，Light验证旨在用于单个块生成器的节点网络的内部，它不打算用于连接到其他块生成器的P2P节点，因为在生成器之间遍历P2P网络的块必须继续完全验证为了保持区块链的完整性。
Meet wabt, the new WASM backend (#5416)
We have replaced the existing binaryen interpreter with wabt (pronounced “wabbit”), a suite of tools for WebAssembly that is considerably faster than the current default binaryen interpreter. This means that every microsecond spent processing transactions on an EOSIO-based blockchain can be more productive. Additionally, we expect that the replay time for existing chains can be cut in half. For more information on wabt you can review the project directly on github here.
我们已经用wabt（发音为“wabbit”）替换了现有的binaryen解释器，这是一套WebAssembly工具，它比当前默认的binaryen解释器快得多。 这意味着在基于EOSIO的区块链上每微秒花费的处理事务可以提高工作效率。 此外，我们预计现有链条的重播时间可减少一半。 有关wabt的更多信息，您可以在此处直接在github上查看项目。 The best part is, as this is all backend mechanics powering the EOSIO platform, no additional development complexity is needed to see these benefits. New developers will be able to more easily set up a node, lowering the barrier to entry to start using the EOSIO blockchain.
最好的部分是，因为这是为EOSIO平台提供动力的所有后端机制，所以不需要额外的开发复杂性来实现这些优势。 新开发人员将能够更轻松地设置节点，降低进入门槛以开始使用EOSIO区块链。
EOSIO Contract Development Toolkit (EOSIO.CDT)
A core part of writing applications for EOSIO is writing C++ smart contracts compiled to WASM. Previously, we recommended using the eosiocpp utility, which was included as a part of the EOSIO build. You may have seen that there is a deprecation notice posted to the issue here and is displayed to developers when using eosiocpp. Please note that eosiocpp will be gradually deprecated across future releases. It will not be removed immediately, but it is strongly recommended to begin transitioning.
为EOSIO编写应用程序的核心部分是编写编译为WASM的C ++智能合约。 以前，我们建议使用eosiocpp实用程序，该实用程序作为EOSIO构建的一部分包含在内。 您可能已经看到此处发布了一个弃用通知，并在使用eosiocpp时向开发人员显示。 请注意，eosiocpp将在以后的版本中逐渐弃用。 它不会立即删除，但强烈建议您开始转换。
That said, with the release of EOSIO V1.3.0, we are excited to announce a new toolkit we will start recommending for compiling smart contracts and generating ABI files — the EOSIO Contract Development Toolkit (EOSIO.CDT). EOSIO.CDT provides support for Gnu & C++ 11 style creating a more reliant way of declaring your smart contract structure and associated data structures.
T也就是说，随着EOSIO V1.3.0的发布，我们很高兴地宣布一个新工具包，我们将开始推荐编译智能合约和生成ABI文件--EOSIO合同开发工具包（EOSIO.CDT）。 EOSIO.CDT为Gnu和C ++ 11风格提供支持，创建了一种更加依赖于声明智能合约结构和相关数据结构的方式。
This has been available on github in experimentation mode for some time, but has reached enough stability where it will start having its own release cycle independent of EOSIO core. At the moment, to start using EOSIO.CDT it must be compiled from the source found here, but stay tuned for coming releases where we plan to include the precompiled binaries.
这已经在github上以实验模式提供了一段时间，但已达到足够的稳定性，它将开始拥有独立于EOSIO核心的自己的发布周期。 目前，要开始使用EOSIO.CDT，必须从此处找到的源代码编译，但请继续关注我们计划包含预编译二进制文件的即将发布的版本。
