Two weeks ago, Steemit announced the launch of a "testnet" for community members, developers, and witnesses to test hardfork 20. The details are in this post.
For those who don't know what a testnet is, basically it is a parrallel version of the blockchain where everything is fake. Whatever you do there does not occur on the actual blockchain, so it is safe for people to test things without worrying about the consequences. (Just make sure you are connected to the testnet.)
Steemit is running an API node that people can connect to for tests:
https://testnet.steemitdev.com
They also have a condenser instance up and running for anyone who wants a GUI interface (similar to steemit.com):
https://condensertestnet.steemitdev.com/
Several of the witnesses are running seed nodes to help support the network infrastructure of the testnet blockchain:
p2p-seed-node = testnet.steemitdev.com:2001 # @steemit
p2p-seed-node = test.steem.house:2001 # @gandalf
p2p-seed-node = p2ptest20.followbtcnews.com:2001 # @followbtcnews
p2p-seed-node = testnet.steemviz.com:2001 # @ausbitbank
p2p-seed-node = velocity.steemtestnet.superawesome.roelandp.nl:2101 # @roelandp
p2p-seed-node = testnet.cervantes.one:2001 # @cervantes
Today I am announcing the addition of a new "Full" RPC testnet node:
testnet.timcliff.com
The node has the following plugins enabled:
chain webserver p2p json_rpc witness account_by_key tags follow market_history database_api account_by_key_api network_broadcast_api tags_api follow_api market_history_api witness_api condenser_api block_api account_history_rocksdb account_history_api
With the following account history whitelist ops:
transfer_operation transfer_to_vesting_operation withdraw_vesting_operation interest_operation transfer_to_savings_operation transfer_from_savings_operation cancel_transfer_from_savings_operation escrow_transfer_operation escrow_approve_operation escrow_dispute_operation escrow_release_operation fill_convert_request_operation fill_order_operation claim_reward_balance_operation author_reward_operation curation_reward_operation fill_vesting_withdraw_operation fill_transfer_from_savings_operation delegate_vesting_shares_operation return_vesting_delegation_operation comment_benefactor_reward_operation
The node supports both HTTP and HTTPS
http://testnet.timcliff.com
https://testnet.timcliff.com
It also has support for cli_wallet connections:
ws://testnet.timcliff.com
wss://testnet.timcliff.com
Here are a few examples of it in use:
curl:
curl https://testnet.timcliff.com --data '{"jsonrpc":"2.0","id":0,"method":"condenser_api.get_account_history","params":["poloniex", -1, 10]}'
cli_wallet:
cli_wallet -s wss://testnet.timcliff.com
unlock "secretpassword"
list_my_accounts
There may be brief periods of time when the node is down due to periodic maintenance and testnet outages. I plan to maintain the node until HF20 testing is complete and HF 20 is live/stable on the main-net.
