+
+The log API of zink is derived by the trait `Event` which provides methods
+`log0`, `log1`, `log2`, `log3`, `log4`. We current only supports static
+bytes in this API.
+
+```wasm
+(module
+  (type (;0;) (func))
+  (type (;1;) (func (param i32 i32 i32 i32)))
+  (import "evm" "log1" (func (;1;) (type 1)))
+  (import "env" "memory" (memory (;0;) 17))
+  (func (;1;) (type 0)
+    i32.const 1048576
+    i32.const 4
+    i32.const 1048580
+    i32.const 4
+    call 0)
+  (export "log1" (func 1))
+  (data (;0;) (i32.const 1048576) "Pingpong"))
+```
+
+The static byte array will be compiled to the data section of wasm, `zinkc`
+gets it from the data section then process it to the logging interfaces.
