I read your preview, and very interested. Quite succinctly and clearly all described. Tell me whether you will have more open information on solidity++ and what will be the fundamental difference from smart contracts based on Eth.
We will open more info about solidity++, please stay tuned.
The most difference between eth and vite are:
- Communication between contract is asynchronous
- In solidity++, it's more like a asynchronous programming
For example:
In solidity:
Code:
pragma solidity ^0.4.0;
contract B {
function add(uint a, uint b) returns (uint ret) {
return a + b;
}
}
contract A {
uint total;
function invoker(address addr, uint a, uint b) {
// message call to A.add()
uint sum = B(addr).add(a, b);
// use the return value
if (sum > 10) {
total += sum;
}
}
}
contract B {
function add(uint a, uint b) returns (uint ret) {
return a + b;
}
}
contract A {
uint total;
function invoker(address addr, uint a, uint b) {
// message call to A.add()
uint sum = B(addr).add(a, b);
// use the return value
if (sum > 10) {
total += sum;
}
}
}
In solidity++:
Code:
pragma solidity++ ^0.1.0;
contract B {
message Add(uint a, uint b);
message Sum(uint sum);
Add.on {
// read message
uint a = msg.data.a;
uint b = msg.data.b;
address sender = msg.sender;
// do things
uint sum = a + b;
// send message to return result
send(sender, Sum(sum));
}
}
contract A {
uint total;
function invoker(address addr, uint a, uint b) {
// message call to B
send(addr, Add(a, b))
// you can do anything after sending
// a message other than using the
// return value
}
Sum.on {
// get return data from message
uint sum = msg.data.sum;
// use the return data
if (sum > 10) {
total += sum;
}
}
}
VITE, another dag project! there are too many cryptocurrency about this technology existed by now. in my survey, more than fifteen ones have died, and more than forty ones are still alive, so in this field, it's competitive extremely. For these ones, Iota,nano,fancom&Rchain maybe famous for public, especially iota. DAG as a creative consensus other than chain, have another future. many professional teams aim to it to make some great work ! maybe Vite,is just the one which has a strong technology team and a clear roadmap. in a short word, VITE is a decentralized application platform connecting the nano's block lattice DAG with ehtereum smart contact concept, is compatible with ehtereum Dapps, and better than fantom. Hope it to arrive it's great goal!
