Contrato SFC

El contrato SFC es un punto de entrada para convertirse en validador o delegado.

El contrato SFC es responsable de:

• Creación de nuevos validadores y delegadores

• Retirada de validadores y delegadores

• Distribución de recompensas

El contrato SFC es un punto de entrada para convertirse en validador o delegado.

Inicializar el SFC

Para utilizar el contrato SFC en la consola hay que inicializar el contexto del contrato.

abi = JSON.parse('SFC_ABI_OUTPUT')
// Note: defina la variable sfcc (en lugar de sfc) para evitar conflictos con el espacio de nombres sfc introducido en go-lachesis v0.7.0-rc1.
sfcc = web3.ftm.contract(abi).at("0xfc00face00000000000000000000000000000000")

La versión actual de sfc es 3.0.4-rc.2.
