Ethereum: What is the alt stack?

Understanding Ethereum’s Alt Stack: Explaining op_toalstack and op_fromalstack

In the world of cryptocurrency, understanding Recently, we’ve been digging into the Bitcoin wiki script page ( where we were discovered two opcodes that piqued our curiosity: op_toalstack and op_fromalstack. In this article,

op_toalstack

The first opcode, op_toalstack, is often referred to as the “alt-stack” op Data from the main bitcoin network). When a script on an alt-chain tries to call a function with an argument that is not present in its local memory, it needs to use the op_toalstack opcode.

Here’s a Simplified Example:

`C

0x40 // Define and New Script (Bitcoin)

0x28

| 0x20

/ 0x8

/ 0x90

/ 0x88

“Myfunction” on the Bitcoin script. Since we’ve declared a variable myaltchain with value 123 earlier in the script, we can use it as an argument when calling the function.

op_fromalstack

The second opcode, op_fromalstack, is used when a script needs to access data This opcode is commonly used for interactive with scripts on different chains using smart contracts or other mechanisms.

Here’s Another Example:

`C

0x40 // Define and New Script (Bitcoin)

0x28

| 0x20

/ 0x8

/ 0x90

/ 0x88

In The Op_Fromalstack opcode is used to access the data stored.

Conclusion

The opcodes op_toalstack and op_fromalstack are an essential part of Ethereum’s Alt Stack, allowing scripts on different chains to interact with each other using smart contracts and other mechanisms. Understanding these opcodes can help develop

The usage of op_toalstack and op_fromalstack, users can unlock new possibilities for creating decentralized applications (DApps) that seamlessly interact with scripts on different alt-chair networks.
