API update for mining pools

Node daemon (Talleod) version 0.4.6 introduced new field in response to “getblocktemplate” API call. Field “num_transactions” now contain number of transactions included in the block template excluding the coinbase transaction. This can be directly used by mining pool to decide when the current block template might need to be refreshed…

Mining pool can either refresh the block template when the field value changes from 0 to non-zero, or when it changes from one non-zero to any other non-zero value while block height stays the same.

Daemon crashing on sync…

We have noticed Talleod crashing on Linux when it tries to sync with other nodes and one of the received transactions has very high anonymity level. This did cause buffer overflow in transaction validation. As a fix, we are limiting mixin count to maximum of 50.

Mining pools getting lots of rejected blocks

Due to block validation rule change at block height 10000, back-end software for mining pools need a patch. Every time a block submission is attempted, cached block template must be discarded, disregarding result of the block submission. This is because the cached block template might not have required amount of transactions and daemon has rejected it for that specific reason.

Missing msvcr120.dll when running Windows applications

Some of our users have reported that xmr-stak linked from our official website fails to run with error message saying msvcr120.dll can’t be found. This file is part of Microsoft Visual C++ 2013 run-time. As our builds are compiled using Visual C++ 2017 (15.9), we have not bundled installer of the older run-time libraries.

There is known issue with some of the builds of Visual Studio C++ 2013 run-time installers that cause the files getting deleted if both 32-bit and 64-bit versions are installed. For more information, please read the official Knowledge Base article (KB3138367).

Network stall on December 7th, 2019

Network stalled on block height 10008 due to logic flaw in pool software on official pool. It was not requesting new block from daemon after daemon rejected previous block submission.

We rewrote the code that refreshes miner jobs to not blindly compare block height of the current job with block height of the network and instead refresh the block after every block submission attempt.

The original code was polling for new block template every 1 second, but didn’t refresh the miner jobs until block height changed. This was obviously incorrect. We restricted the loop to only initial startup of the pool.

Main net launched

Main net was online 41 seconds after midnight (UTC) on December 1st, 2019, as first block was successfully mined. After the network was stabilized and premine wallet was synced, all pool balances of at least 1.00 TLO were paid from premine to same wallet addresses as used on two listed pools on testnet.

Switch to mainnet

Talleo seed nodes, block explorer, and mining pools operated by team members, will have scheduled maintenance starting on November 30th to prepare switch to mainnet.

All paid and pending balances on mining pools will be backed up before the pool databases are erased and pool wallets are reset.

After successful switch to mainnet, backed up balances are paid to original addresses used when logging in on mining pools.

Swap from Bittorium to Talleo will start after premine has unlocked, which will take exactly 10 blocks from start of the mainnet.

Swap from Bittorium

From December 1st, 2019 to December 31st, 2019 users of Bittorium can swap their coins at rate of 10 BTOR to 1 TLO by sending their BTOR coins to wallet address bTXPouErxAPNQ9Ajwtn7NE589BiU7vb8y9rRow3vZYerBVA9AL2RGb498XgkXwYpUMLagvWSYfHEmW3X2LqCxd7214jA6JuyA and e-mailing the transaction hash and Talleo wallet address to dev@talleo.org.

If the amount is larger than 1 million BTOR, screenshot of the wallet application showing the swap transaction must be sent when requested.
