#include "eoslib/print.hpp"  
#include "BigIntegerLibrary.hpp"  

 BigInteger a = 65536;  
 print("a * a * a * a * a * a * a * a: ", ( a * a * a * a * a * a * a * a ) );

then, eosd prints 340282366920938463463374607431768211456.

配置自己的节点与EOS主网数据同步

2018-06-15　 Surou　阅读　 EOS-新手教程　 0 评论

本篇文章将讲解如何将自己机器部署的节点链接到EOS主网，并同步区块数据。

1.源码编译

源码编译部分请参考（EOS 在Ubuntu 16.04 编译及安装）

2.修改config.ini

修改producer-name为自己的节点名，例如producer-name = eos.dos
修改private-key为自己的公钥私钥（在线生成）
添加p2p-peer-address 一些已知稳定访问的公网节点
三种方式获取可用的p2p-peer-address:

p2p-peer-address = node1.eosnewyork.io:6987
p2p-peer-address = p2p.eos42.io:9876
p2p-peer-address = peering.mainnet.eoscanada.com:9876
p2p-peer-address = node1.starteos.io:9876

按自己需要添加一些插件支持

plugin = eosio::chain_api_plugin
plugin = eosio::history_api_plugin
plugin = eosio::chain_plugin
plugin = eosio::history_plugin
plugin = eosio::net_plugin
plugin = eosio::net_api_plugin

在~/.local/share/eosio/nodeos/config目录下执行（目录可随意）

wget https://github.com/EOS-Mainnet/eos/raw/mainnet-1.0.5/mainnet-genesis.json

在上面目录下执行nodeos --genesis-json mainnet-genesis.json
出现错误Genesis state can only be set on a fresh blockchain
修改执行命令为

nodeos --genesis-json mainnet-genesis.json --delete-all-blocks

执行cleos get info查看chain_id

已经为EOS主网络。
