[Clarification Request] 1.2.2. Create a one-way Bitcoin ordinary transfer transaction

(1) What does this line mean:

amount [int] The amount of bitcoins to be paid, in units of "satoshi" and "satoshi" (0.00000001 bitcoins); for example, if you transfer 10 bitcoins, you will pass "1000000000", and if you transfer 0.01 bitcoins, you will pass "1000000"; the system does not Bitcoin units below 1 satoshi are supported.

(2) What private key to be used to transfer using API: main_prikey:

 http://rpcapi.hacash.org/create?action=value_transfer_tx&main_prikey=8D969EEF6ECAD3C29A3A629280E686CF0C3F5D5A86AFF3CA12020C923ADC6C92&fee=0.0001&

And

If Hacash then how can we transfer Bitcoin to the address without knowing its key | else if Bitcoin how does 'a bitcoin' transferred into the Hacash Chain? Since the BTC is on a different chain?

Summary of Data Races associated with [*DeprecatedApiService]

Summary of Data Races associated with [*DeprecatedApiService]

• Text file of instrumented Diamond Miner [DiamondMiner_log_Sep_21_2021.txt], available via Github Gist [https://gist.github.com/dwymi02/95140687b566efa22939dec3cd14dd6d]

• The instrumented binary was built from refreshed code, dated Sep-21-2021.
  The source code repository was wiped clean and "git clone ..." was used to create the updated code base.

• The instrumented code was built with "-race", e.g., "go build -race".

• The directory [hacash_mainnet_data/] was completely removed, to allow the Hacash blockchain to be built from scratch, also allowing for additional Data Races to be uncovered, if any.

• In searching for Data Races I tried to group them based on specific Hacash components.
  Grep was used to search for known Hacash components, following is a list of potential Data Races, based on Hacash components:

  • A search for [*P2P] returned 109 hits
  • A search for [*Block_v1] returned 4 hits
  • A search for [*ChainState] returned 3 hits
  • A search for [*DiamondMiner] returned 45 hits
  • A search for [*DeprecatedApiService] returned 33 hits
  • A search for [*Transaction_2_Simple] returned 14 hits
    While there are large numbers of potential hits, there Hacash components may or may not be proximate to the actual Data Race.

  For each Hacash component I will list the specific Data Race.
  When the current code does not match what was previously built, a [*** NOTE ***] will be included
  In the event the stack trace that is too lengthy, the results will be truncated.
  If it is necessary, the full log will be provided, as needed.

  For the specific Read and Write that are involved in the Data Race, the [<===] will be used to identify where the specific Read/Write occurred, based on current source available ...

  Once the Data Race has been documented, an issue will be opened on Github.
  I will leave it to your team to decide how the Data Race is to be handled.
  You can opt to fix the Data Race or simply close the issue. as you so choose.
  This decision I leave with you and your team ...

Help me!

Hello
I am going to use quoteFee api in HaCash.
How to set url?
I set url to https://wallet.hacash.org/api/quote_fee but not found.

address not displayed in top 100 HAC addresses

I have 2 addresses with enough coin to be in the top 100 list, however only 1 of the addresses is there. The other is not. I have not transacted for a very long time, so its not as if the blockchain just needs to catch up. Seems like a bug.
