Portal Loop

Portal Loop is an always-up-to-date staging testnet that allows for using the latest version of Gno, Gno.land, and TM2. By utilizing the power of Docker & the tx-archive tool, the Portal Loop can run the latest code from the master branch on the Gno monorepo, while preserving most/all the previous the transaction data.

The Portal Loop allows for quick iteration on the latest version of Gno - without having to make a hard/soft fork.

Below is a diagram demonstrating how the Portal Loop works:

Using the Portal Loop​

The Portal Loop deployment can be found at gno.land, while the exposed RPC endpoints can be found on https://rpc.gno.land:443. The RPC endpoint list can be found in the reference section.

A warning note​

While allowing for quick iteration on the most up-to-date software, the Portal Loop has some drawbacks:

  • If a breaking change happens on master, transactions that used the previous version of Gno will fail to be replayed, meaning data will be lost.
  • Since transactions are archived and replayed during genesis, block height & timestamp cannot be relied upon.
