Explanation of Solution

Blockchain fork:

  • It generally occurs when a block is being added to the block other than the most recent one in the chain is called as blockchain fork.
  • The blockchain is forked in order to change the aspect of protocol or its data structure.
  • Forking will occur when a malicious activity occurs.

Explanation of Solution

Two types of block chain fork:

There are two types of block chain fork and they are:

  • Soft fork
  • Hard fork

Difference between them:

Soft fork occurs at the rare case and will cause major controversy but does not invalidate prior block but whereas the hard fork will do it that is in a hard fork an older version of the block chain software will remain in use and it will lead to separate block chains that holds different contents in them.

Just wanted to know, if you had a scene graph, how do you get multiple components from a specific scene node within a scene graph? Like if I wanted to get a component from wheel from the scene graph, does that require traversing still?   Like if a physics component requires a transform component and these two component are part of the same scene node. How does the physics component knows how to get the scene object's transform it is attached to, this being in a scene graph?
How to develop a C program that receives the message sent by the provided program and displays the name and email included in the message on the screen?Here is the code of the program that sends the message for reference: typedef struct {    long tipo;    struct {        char nome[50];        char email[40];    } dados;} MsgStruct; int main() {    int msg_id, status;    msg_id = msgget(1000, 0600 | IPC_CREAT);    exit_on_error(msg_id, "Creation/Connection");    MsgStruct msg;    msg.tipo = 5;    strcpy(msg.dados.nome, "Pedro Silva");    strcpy(msg.dados.email, "pedro@sapo.pt");    status = msgsnd(msg_id, &msg, sizeof(msg.dados), 0);    exit_on_error(status, "Send");    printf("Message sent!\n");}
